About R
Waqar, Just extract the source file downloaded from CRAN and examine the contents of the "R" directory. Best, Thiago.

I solved my problem. Now i want to look at the source codes of different function used in the verification package of R for example, the code of the function verify, attribute etc. Can any one help in this regard?

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. Best, Philipp On 10.02.2011 01:07, waqar younas wrote:
Thank you very much for your kind response. I looked at the document and found the
alternative of size in R which
dim(). But the reshape function in the
document for MATLAB is not
completely specified. In MATLAB when we do
reshape, we simply use this
command, if my file name "data" has this dimension
(12,396*10) and i want to
change it into three dimension then i will
use in MATLAB as
reshape(data,120,396,10). In the document you sent to me, the reshape
function for MATLAB is
only given for 2 dimension and i think the
script of the function is
not correct. That is why its alternative in R
is also limited to 2
dimension. Can you help me in this regard? On Wed, Feb 9, 2011 at 4:20 PM, Philipp
