Have a look at ?array
its use in comparison to MATLAB's reshape is in fact described in the Hiebeler-matlabR.pdf that Arien mentioned yesterday. If you want to stick to MATLAB-like syntax, the matlab package has a function reshape that should do exactly what you want: http://cran.r-project.org/web/packages/matlab/ There is a wealth of information out there on porting code between R and Matlab as well as basic R functionalities. http://www.rseek.org and the R-help mailing list have been mentioned before.
