MATLAB: How to convert ,mat data file to R

MATLAB

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 ...
