Hi
I am using Ubuntu 8.04 64 bit, R as below, Matlab 7.6.0. I would like to transfer mat files back and forward between R and Matlab. Whilst I have used Matlab for years its been a long time since I have used R (hence question may be a bit simple)
Running code
A <- c(1:10)
dim(A) <- c(2,5)
library(R.matlab)
writeMat('A.mat', A=A)
Does not appear to generate any mat file either in local directory or in /tmp/R*
I tried both current version of R.matlab and older version because of bug
https://stat.ethz.ch/pipermail/r-help/2008-September/173432.html
A <- matrix(1:27, ncol=3)
B <- as.matrix(1:10)
fn <- paste(tempfile(), ".mat", sep="")
writeMat(fn, A=A, B=B)
data <- readMat(fn)
print(data)
unlink(fn)
onWrite <- function(x)
writeBin(x$length, con=x$con, size=4, endian="big");
writeMat(fn, A=A, B=B, onWrite=onWrite)
Does generate a file in /tmp/Rtmpjhfjxw
-rw-r--r-- 1 dst dst 396 2008-09-27 12:46 file643c9869.mat
When I try to read it into Matlab I get
??? Error using ==> load
Unable to read MAT-file /tmp/Rtmpjhfjxw/file643c9869.mat
File may be corrupt.
(This is same error message as above link and occurs with old and current version of R.matlab)
Any advice would be very helpful
Regards
Douglas
