R help - May 2005 - General Question on learning R...

In the process of learning R, with a specific interest on financial
time series.  While I continue to get through the documents I am more
a fan of learning by example and then looking up how each function is
used.  Any websites which post sample code for R?

Thanks in advance.

The largest source of example code is R itself.  If you have a command 
in which you are interested, you can often just type the command and 
the code will be shown to you.  Try typing:

ls()

Then:

ls

It will show you the code used to produce the result.  Also, each 
command has its own example(s) in the help.

For an installed package (rather than source), the R-ex/ directory contains
the code in the Example section of help pages; e.g., if you run
example(somefun), the code in somefun-ex.R is source()'ed.

Stuff in the demo/ directory are executed by the demo() function, and it's
optional:  Most packages do not have demo code.
