The OP wrote me privately to say that the errant documantation was at:
http://lib.stat.cmu.edu/S/Harrell/help/Hmisc/html/ecdf.html
That is a rather old bit of information. It dates back to a time when
Frank's address was at the the University of Virginia. In 2003 he
moved to Vanderbilt so that page dates from some year prior to 2003.
(And it may not currently be under the control of anyone given its
quasi-archival status.)

Hi Thierry,
That worked perfectly. Thanks for the suggestion.
For reference, in the documentation, it

R is case sensitive. ecdf() is in the stats package, Ecdf() is in
Hmisc.
So you want Ecdf(x,what='1-F')

Hello,
I'd like to plot an empirical cumulative distribution
function, except instead of the fraction of values < x, I'd
like the fraction of values > x.
I think this can be done using the ecdf function in {Hmisc}.
I installed the package and loaded it. However, when
following the example given in the documentation, I get an error:
x <- rnorm(100)
ecdf(x,what='1-F')
Error in ecdf(x, what = "1-F") : unused argument(s) (what = "1-F")
I believe that this is because R is attempting to access the
ecdf function in base R, which does not have the what option.
Am I correct, and if so, how can I change that?
Note: I also tried to "do it myself" without the {Hmisc} ecdf
function, and couldn't figure out a way.
x2 <- 1-ecdf(x)
doesn't work, and neither does
x2 <- rep(0,times=100)
for(i in 1:100){
x2[i] <- 1-ecdf(x)[i]
}
Both result in errors.
Thanks in advance for any suggestions you can offer.
-Mitch
