How to see any R package code?

    Dear All,
    I have modified a .R code (/usr/local/lib/R/site-library/brainwaver/R), but
    when I run it, why does it run the original code? Whatever I modified it,
    the results did not change.
    what happened?

   

Hi Zhijiang,
If you modify a source code file in an external editor, you must save 
the result, then use:

source("usr/local/lib/R/site-library/brainwaver/R/mycode.R")

where "mycode.R" is the name of the file that you have modified. The 
code that you "source" will replace the previous code. It looks like you 
are modifying the code of one or more functions in the brainwaver 
package, so when you have the function working as you wish, you will 
probably want to rebuild the package, perhaps renaming it to something 
like brainwaver2. See "Writing R extensions" (R-exts.html) for 
information on how to do this. You would then be able to use:

library(brainwaver2)

instead of the original library.
