Hi,

Is there a way I can view the functions source code of  a
package I installed in my PC.

For example I downloaded the great "mixtools" package.
I want to see the source code of one of its function "normalmixEM"

Is there a way to do it? Presumably from R command prompt?

I tried to take a look at the zip file, but somehow I can't seem
to find the file on which I can find the source code. Please advice.

Hi,

You can see the R-source code of a function if you give the command without the brackets. For example:

> sort
function (x, decreasing = FALSE, ...)
{
   if (!is.logical(decreasing) || length(decreasing) != 1)
stop("'decreasing' must be a length-1 logical vector.\nDid you intend to set 'partial'?")
   UseMethod("sort")
}
<environment: namespace:base>

Another option is to download the .tar.gz source package from CRAN, unpack it and the R source code is available in the "R" subdirectory.

cheers,
Paul
