Reading .mat file in R

Question

I am unable to parse a list of values read from a.mat file.

library('rmatio')
eyes_open <- read.mat('Documents/TE/Implementation/DP23EyesOpen.mat')
print(str(eyes_open))

Running the script above produces:

$ mat1: num [1:30, 1:2000] -0.567 -0.54 -0.356 -0.43 -0.274 ...
NULL

I need a 30x2000 matrix, but I'm not sure how to get it from this list.
