R help - Nov 2003 - cumulative distribution functions

hi y'all,

I am wondering if there is any special command, function, 
package, etc to help me doing a cumulative distribution function, 
with y-scale - probability scale.

I tried the help in R and i got the following answers:
cumsum(base)            Cumulative Sums, Products, and Extremes
ecdf(stepfun)           Empirical Cumulative Distribution Function
cpgram(ts)              Plot Cumulative Periodogram

But i could not find either (stepfun) nor (ts) packages to read the 
specific help. Are they discarded? The "cumsum" seems not to do 
what i really was after.

Any help as usual very much appreciated ;-)

Monica

Try  help("INSTALL")  (case-sensitive).

Hi,

the packages i mentioned are not in the list of packages from 
CRAN even if they appear in the help i just mention an email later 
about cumulative distribution functions. they are "stepfun" and
"ts".
Maybe that helps to clarify my question - in the sense that i know 
how to look after packages on CRAN and how to install them.

Thanks,

Monica

OK,

I see what i did .... i though stepfun and ts are two packages on 
CRAN - i didn't realized they are libraries already "installed"
under
R .... now i found them .... mea culpa!

Thanks a lot,

Monica

You need to execute "library(stepfun)" before help for ecdf will work.

In general, the notation is

topic(package)	Description

and you need library(package) to see ?topic.
