To debug a function, what I currently know is to put 'browser()'

it. But I'm wondering if there is a way like 'step in' that is
available in debuggers of other languages (e.g. gdb).
Learn to search:
library(sos)
???"debug step"
I download the document from cran. But I prefer to consult the
document from R session. What command should I use to get the
document
for the package of sos?
The same way you would install any other package.
What command should I use to get the list of
functions that are in sos?
Most packages have an index. Some will display a list with:
help(package= <pkg-name> )
(Do you read r-help? Did you read any basic material? Seems as
though this
much should have crossed your eyes and brain before. )
I used some other method to look for functions that are available from
other packages. But it didn't work for sos. And I was aware of the
package argument to help().
If it is still not clear, then do it the old fashioned way. Either
<RTFM> i.e. http://cran.r-project.org/manuals.html ... or
RSiteSearch("install packages")
