I am sorry for such a simple question but I just could not find a command to list functions (objects) in a certain library. I had to refer to library documents (often not readily available ) to find them. Many thanks in advance. -- Bo Peng

If you really want to know about the functions (and not all objects) in a package try lsf.str("package:ts") which gives the call sequences too.> > On Mon, 31 Mar 2003, Bo Peng wrote: > > > Date: Mon, 31 Mar 2003 21:34:50 -0600 > > From: Bo Peng <bpeng at stat.rice.edu> > > To: r-help at stat.math.ethz.ch > > Subject: [R] How to list functions in a library? > > > > I am sorry for such a simple question but I just could not find a > > command to list functions (objects) in a certain library.

Hi, Which library is it? If it is a proper R library and has been properly installed, I think you should be able to do something like: library(help = ts) # Get the list of functions in ts package In fact that will also show some information about the library itself.

nm - list symbols from object files (.o .a .so etc.) - maybe that is what you want? nm something.so Bo Peng wrote:> I am sorry for such a simple question but I just could not find a > command to list functions (objects) in a certain library.

Thank you all for your apply. Both commands works. For example,
library(help=MASS)
will list function names with description and
ls(package:MASS)
will list all object names.
