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,
When you want to look at the code of a particular function, pass the
command without the brackets, e.g. for lm:
> lm
Alternatively, you can download the source package and go to the
subdirectory R/. All the R code is located there.
cheers,
Paul

For a code .R file, I add a function in it.
But I saw it was not modified in command window, while it was changed in
"/usr/local/lib/R/site-library/brainwaver/R" by openning it by
editor.
So I doubt the two are different, but I just find one version this .R file,
which was just in the above directory.

Thank you Jim!
The problem is solved now.

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.

You have a couple of options: 1) typing the name of the function will list the source within your R console. For example:> lswill list the source code for the ls() function. So once you load your package, you can simply enter the name of the function whose source you wish to see and you will see. 2) The above will not work if the function has not been exported via the NAMESPACE file. In this case you have to download the .tar.gz file from CRAN to view the source. After you unzip and untar the downloaded file, you can look in the R/ or src/ directories for the function you are interested in. As the names suggest, R/ contains R code, while src/ contains C or Fortran code used in the package.
