[R] Requesting for help on the problem of "subscript out of bounds"
Hello,
Instead of nrow try all uppercase:
N <- NROW (ts)
Hope this helps,
Rui Barradas?

Requesting for help on the problem of "subscript out of bounds"
Hello Sir,
I tried by defining mat, but still facing the same problem.
Hence, mat represents the time series. This time, I defined it as ts and
tried, but still having the same problem.
In particular, the problem is coming in the following line
*for (i in 1:N){*
*+???? r[i]<-approx_entropy(ts[i,], edim = 2, r = 0.2*sd(ts[i,]), elag 1) *
where i is unable to synchronize with the no. of rows i.e. rows and thus I
am getting the error of
*Error in `[<-`(`*tmp*`, i, , value = ts[i:(N - m + i)]) :?? subscript out
of bounds*
For your reference, I am providing my full code with an explanation as
follows.
The function
approx_entropy(ts, edim = 2, r = 0.2*sd(ts), elag = 1)
from the package,pracma I am calculating the approximate entropy of time
series.ts
I have a matrix of time series (one series per row i.e. 51 rows and 1
column)? and I would estimate the approximate entropy for each of the rows,
storing the results in a vector. So, I have written a code
library(pracma)
N<-nrow(ts)
r<-matrix(0, nrow = N, ncol = 1)for (i in 1:N){
???? r[i]<-approx_entropy(ts[i,], edim = 2, r = 0.2*sd(ts[i,]), elag = 1)}
* After calculating for 1 series, I need to calculate the same things for
the multiple series by changing the dimension of the ncol.*
Please help me in this regard.
Thanks in advance.

[R] Requesting for help on the problem of "subscript out of bounds"
I am extremely sorry to say that both the suggestions did not work. I did not understand the suggestion of Prof. Lemon. So, Sir, Can you please clarify me your suggestion? I tried the suggestion of Ruipbarradas. It does not work. Please help me out for which I shall be always grateful to you. Thanks in advance.

[R] Requesting for help on the problem of "subscript out of bounds"
The idea of using:
cat("i =",i,"\n")
is to display the value of i each time the loop executes. Displaying i
_before_ the error occurs tells us what value of i is causing the
problem. Because the error is occurring when you try to index ts,
perhaps adding:
cat(dim(ts),"\n")
for(i in 1:N) {
...
_before_ the loop starts will tell you what the dimensions of ts are.
It way well be a list that you have to use a different syntax for
indexing. An even more complete description of ts can be had like
this:
str(ts)
Unfortunately I am about to log out and get some sleep so I will not
be able to continue answering until some time tomorrow.

[R] Requesting for help on the problem of "subscript out of bounds"
Hello, I suggested NROW (all uppercase) because it works even if its argument, in your case ts, has only one dimension, nrow needs 2-dim objects. I have now noticed that you are indexing ts as if it has two dimensions, and that r is created with function matrix() but then you index it with just one dimension. r[i] <- approx_entropy(ts[i,], edim = 2, r = 0.2*sd(ts[i,]), elag = 1) Shouldn't it be ts[i] or r[i, ] ?
