I found a bug in "Execute R" operator
I am using R-3.6.0
Briefly, "Execute R" cannot compute mean function of R
data[1,1] <- mean(data[3:5,4])
but it didn't work and why it didn't is written in the log file I attached
I believe it will not be able to compute var function either.
I attached the process and log files.
Please fix this problem for me
Thank you and have a nice day.
