Hi,
Searching for functions that would order strings that mix characters and
numbers in a "natural" way (ie, "a1 a2 a10" instead of "a1 a10 a2"), I found
the mixedsort and mixedorder from the gtools package.
Problems:
1- mixedorder does not work in a "do.call(mixedorder, mydataframe)" call lik

Hi Neha,
This might help:
R<-read.table(text="C1 C2 C3 C4
R1 0 1 0 1
R2 1 0 1 1
R3 1 0 0 0",
header=TRUE)
U<-read.table(text="C1 C2 C3 C4
U1 1 1 0 1
U2 1 1 1 1",
header=TRUE)
# these are matrices - I think this will work for dataframes as well
for(ui in 1:dim(U)[1]) {
for(ri in 1:dim(R)[1]) {

cwhmisc package provides essentially the algorithm outlined by Dan.
If you want answers outside your original data (extrapolation) then the
following code at least won't give broken answers, though it is not
necessarily any more "correct" for extrapolation than the approx solution
is.

Hi Christofer,
You may be looking for ecdf (stats) for a start, then working out a
way to translate the cumulative density values into probability
values.

You need to re-read ?density and perhaps think again -- or do some study --
about how a (kernel) density estimate works. The points at which the
estimate is calculated are *not* the values given, nor should they be!

Let say I have below vector of data-points :

-0.184418145956608, -0.
Thank you José María:
You are very kind.
I will study and use your advice.
The first step, takes more information,
but not what I want. (I want the whole data set of "TRM").
I'm going to try with Selenium (RSelenium).
Thank you very much for your help.
