R Error: incorrect number of dimensions (2 Examples)
This tutorial explains how to avoid the error “incorrect number of dimensions” in the R programming language .
The table of content is structured as follows:
Creation of Example Data Example 1: Reproduce the Error – incorrect number of dimensions Example 2: Fix the Error – incorrect number of dimensions Video, Further Resources & SummaryYou’re here for the answer, so let’s get straight to the examples:
Creation of Example Data
We’ll use the data below as basement for this R tutorial:
x <- letters[1:5] # Create example vector x # Print example vector # [1] "a" "b" "c" "d" "e"
Have a look at the previous output of the RStudio console. It shows that our example data is a character vector containing five vector elements.
Example 1: Reproduce the Error – incorrect number of dimensions
In this example, I’ll show how to replicate the error message “incorrect number of dimensions” in R.
Let’s assume that we want to extract a subset of our vector using square brackets. Then, we might try to use a code like this:
x[1:3, 1:3] # Try to access two dimensions of one-dimensional vector # Error in x[1:3, 1:3] : incorrect number of dimensions
Unfortunately, the previous R code leads to the error message “incorrect number of dimensions”.
The reason for this is that we have tried to extract two dimensions from a one-dimensional data object (i.e. a vector). Remember that the comma (i.e. “,”) within square brackets tells R that we want to specify another dimension.
So how can we debug this error message and solve this problem?
Example 2: Fix the Error – incorrect number of dimensions
In Example 2, I’ll explain how to deal with the error message “incorrect number of dimensions”.
To avoid this message, we simply have to specify the correct number of dimensions.
In this example, we are using a one-dimensional vector as basement. For that reason, we should only specify one dimension within the square brackets:
x[1:3] # Properly access values of vector # [1] "a" "b" "c"
The previous R code works fine!

Hi there, i am having trouble getting this warning message “Error in “ozone.txt”[, c(1, 2)] : incorrect number of dimensions” when trying to unstack my ozone.txt data.
data is read in as gardens=read.table(“ozone.txt”, header=TRUE)
and R has correctly read in the data as two columns, $0zone, $Garden.
For this problem, there are two gardens ‘A’ and ‘B’ with different values of ozone concentration, but I am trying to perform a t-test so would like the ozone concentrations organised under Garden type rather than two two just being 2 lists (sorry I know this is basic but I’m new to R!)
when I use the command
gardens1=unstack(“ozone.txt”[,c(1,2)])
i get the warning message.
I have used this before to unstack the data according to the 2nd column. I’m sure its simple but any guidance on the basics of unstacking is greatly appreciated.
Thanks

Hi Bea,
Could you check the classes of your variables Ozone and Garden? You can do that by running the following line of code:
sapply(your_data, class)
What is the output of this line of code?

Hi Joachim,
sorry for delay,
the type data of grid, is a list,
no_lake <- grid[lengths(st_within(grid, lakes)) == 0, ]
Error in `[.default`(grid, lengths(st_within(grid, lakes)) == 0, ) :
incorrect number of dimensions
Look forward of your support, I

Hey Richard,
No problem! What’s the output when you run the following line of code?
lengths(st_within(grid, lakes)) == 0
It should be a vector of logical values (i.e. TRUE and FALSE).
Regards
Joachim
Reply Joachim October 6, 2021 6:40 amOh, and another thing I have just noticed: Does it work when you remove the comma at the end of your code?
no_lake <- grid[lengths(st_within(grid, lakes)) == 0]

Hello Joachim,
I am trying to run a Dun`s correction test for the non-parametric Scheirer-ray-Hare`s test. However, I
I have an error message about incorrect dimensions. Below is the code and what the error message says.
DT = dunnTest( aw ~ Chunk.type , data=data, method=”bh”)
Error in Psort[1, i] : incorrect number of dimensions
In addition: Warning message:
Chunk.type was coerced to a factor.
Please how can I correct this?
Kind regards,
Marisa

Hey Marisa,
Unfortunately, I have never applied the dunnTest function myself. Based on the error message it seems like the data in Psort is not formatted properly.
However, I have recently created a Facebook discussion group where people can ask questions about R programming and statistics. Could you post your question there? This way, others can contribute/read as well, and maybe you get better help there: https://www.facebook.com/groups/statisticsglobe

Hi Joachim, I have results for concentration and purity values of RNA samples that were extracted using two different methods i.e. CTAB and KIT. I’m trying to do the mean difference of, for instance concentration per protocol/method but I can’t get the exact codes for that. Previously when I run stat compare means, the output result showed that there was no significant difference in RNA concentration between the two methods although there was a very being observed difference. I know this question is basic, but because I’m new in R I’m unable to solve it. kindly, help. Thank you

Hi Joachim,
I am having the following problem, and was wondering if you might know what to do:
I am selecting rows from a 1000×10 matrix M in a loop.
When I index the matrix, say with M[,i] outside of the loop, R can easily find the column or row I have indexed.
When I index inside the loop, however, R cannot find it; if I ask it to
“print(M,[,i])” inside the loop, it states
“Error in M[, i] : incorrect number of dimensions”
Please let me know why you think this is.

Just to be clear, the indices are well within the length of the matrix. That I have checked.

This is the question,
From the variable polity2, create a new variable called regime. The new variable regime is supposed
to have three values: if polity2 is -6 or lower, then regime is a “full autocracy”; if polity2 is 6 or
high, then the regime is a “full democracy”; finally, if polity2 is in between -5 and 5, regime is an
“anocracy”. Once you created the variable regime, create a barplot showing the distribution of this
variable.
So far I have this,
regime <- ("data.democracy$polity2")
regime$aut <- ifelse(data.democracy$polity2 <= -6, "full autocracy", -5)
regime$dem = 6, “full democracy”, 5)
regime$ano <- ifelse(data.democracy$polity2 -5<5, "anocracy", -6<6)
##a vector of proportions to plot
ISAF.ptable <- prop.table(table(ISAF = data.democracy$polity2.exp.ISAF, exclude = NULL))
ISAF.ptable
##ISAF
##0 1 2
##-6 6 -5
barplot(ISAF.ptable,
names.arg = c("regime$aut", "regime$dem", "regime$ano"), main = "Democracies",
xlab = "Democracies",
ylab = "Levels", ylim = c(0,40), xlim = c(-10,10))
data.democracy.ptable <- table(data.democracy$polity2.exp.taliban,
exclude = NULL) / nrow(data)
barplot(data.democracy$polity2,
names.arg = c( "Full autocracy", "Full democracy", "Anocracy"),
main = "Regime distribution",
xlab = "Regime classifications",
ylab = "polity score", ylim = c(0,40), xlim = c(-10,10))

It seems like the error message is caused by this line of code:
names.arg = c( "Full autocracy", "Full democracy", "Anocracy"),
Does it work when you create your barplot without this line (see below)? How many bars are shown in this plot?
barplot(data.democracy$polity2, main = "Regime distribution", xlab = "Regime classifications", ylab = "polity score", ylim = c(0,40), xlim = c(-10,10))

Hey Joachim, I don’t know if you still help with code problems, but I’ll try. So it’s a linear trend and I get this error: Error in resid[, i] : incorrect number of dimensions. And my code looks like this:
biblioteki_i_filie <- read_excel("Dane – liczba bibliotek i filii.xlsx",sheet = "DANE", range = "D1:E22")
View(biblioteki_i_filie)
biblioteki_i_filie_ts <- ts(biblioteki_i_filie, start=c(2001,1),frequency = 1)
print(biblioteki_i_filie_ts,calendar=TRUE)
biblioteki_i_filie_learn <-window(biblioteki_i_filie_ts,end=c(2016,1))
print (biblioteki_i_filie_learn, calendar=TRUE)
biblioteki_i_filie_test <- window (biblioteki_i_filie_ts,start=c(2017,1))
print(biblioteki_i_filie_test,calendar=TRUE)
t <- 1:16
t_2 <- t^2
t_3 <- t^3
t_4 <- t^4
t_5 <- t^5
t_ln <- log(t)
biblioteki_i_filie_1st <- tslm(biblioteki_i_filie_learn ~ trend)
summary(biblioteki_i_filie_1st)
plot(biblioteki_i_filie_learn,main="Trend liniowy")
lines(fitted(biblioteki_i_filie_1st),col="green")
And here, I always get this error. I don't understand what is wrong with my code. Can you help me?

Hello Weronika,
To be honest, I am not so familiar with the tslm() function. However, what I understand from your code is that it is something to do with the dimensions of your residuals. Maybe you print the residuals first and see if it is multidimensional and if the plot() function is the best choice to plot them. I understood that you got the error after running the line: plot(biblioteki_i_filie_learn,main=”Trend liniowy”), is it right?

Hello
I want to use PSTR package , when creating new PSTR with
pstr = NewPSTR(dd, dep=’GDP’, indep=4:30, indep_k=c(‘FDI’,’HDI’,’ctrl_corr’,’gov_effec’),
tvars=c(‘ctrl_corr’), im=1, iT=18)
it gives me this message:
Error in `vY[tmp, ]`:
! Can’t subset rows with `tmp`.
x Logical subscript `tmp` must be size 1 or 3268, not 3258.
Run `rlang::last_trace()` to see where the error occurred.
I don’t understand what I will do
please Help

Hello,
Do you have a variable called tmp like an id variable but not shown in your shared code? I understand that its length does not match your data size. Have you tried to use `rlang::last_trace() to see where the error occurred as suggested?

it is requested i have got the results of BEKK-GARCH model, but now i need code for conditional covariance . when i calculate sigma.t it give me 748 4 , means , four columns of 748 rows but i want 2 2 784 instead of 4 784,,,,, would be thankful.
