Hi,
I have a matrix of size 19x512x20 in R.
No, you don't. Matrices are only 2 dimensional in R. You may have an
"array", however.
I want to export this file into
another format which can be imported into MATLAB.
write.xls or write.table exports only one dimension.
please send a code if possible. I am very new to R and have been
struggling
with this.
install.packages(pkgs="R.matlab", dependencies=TRUE)
library(R.matlab)
?writeMat
filename <- "~/test.mat"
writeMat(filename, arr=arr)
> readMat(filename)
$arr
