Hi,
I recently got a task to convert a .mat data file into an R datafile.
I don't know how about R at all. So I am asking any leads on how to convert matlab .mat file into R based data file?
Thanks!

As far as I know R can read MATLAB data using read.mat. So taking the example from here.
>> x = rand(3,4,2)
x(:,:,1) =
0.75127 0.69908 0.54722 0.25751
0.2551 0.8909 0.13862 0.84072
0.50596 0.95929 0.14929 0.25428
x(:,:,2) =
0.81428 0.34998 0.61604 0.83083
0.24352 0.1966 0.47329 0.58526
0.92926 0.25108 0.35166 0.54972
>> save file.mat x
R> library(R.matlab)
R> data <- readMat('file.mat')
R> str(data)
List of 1
$ x: num [1:3, 1:4, 1:2] 0.751 0.255 0.506 0.699 0.891 ...
- attr(*, "header")=List of 3
..$ description: chr "MATLAB 5.0 MAT-file, Platform: PCWIN, Created on: ..."
..$ version : chr "5"
..$ endian : chr "little"
R> data$x
