Hi Sir/Madam,
I'm a researcher in university of Guelph, Canada and now considering
using R to do some data analysis. I'm wondering whether there is a
library available in R that includes algorithms for archetypal
analysis? This is a method quite similar to principal components

Hi
isnt it a homework?
FYI see
?list
?vector
?data.frame
?sample
?lapply
and some basic stuff like Introduction manual provided with your R
instalation to see how some simple data manipulations can be done.

Hello,
Is there a way to convert a character to a number with out getting a warning?
I have a vector that has both numbers and letters in it and I need to convert
it to only numbers. At the moment I'm using as.numeric but it is generating a
warning when it converts a letter. Is there another
suppressWarnings(a - as.numeric(c(1, 2, pi, a, 9, z)))

Please, don't reinvent the wheel: putting functions in a dedicated
environment is one of the things done by R packages (together with a
good documentation of the function, and making them easily installable
on any R implementation).

a lot.
Happy new year every one!

I created environment mytoolbox by : mytoolbox - new.env(parent=baseenv())
Is there anyway I put it in the search path ?

Could somebody please tell me what does the r-help-bounce address do?
When I try to respond to an r-help post, my mailer (Lotus Notes) generates
the r-help bounce return address automatically in addition to the original
sender address and the r-help address. I responded to an r-help message
