Before you can use a package you have downloaded you need to "activate" it.
There are different ways of doing this. Simplest is to type library(ade4).
##
library(ade4)
?discrimin.coa
Follow Bastiaan and read in your file as follows (single forward slashes
also work):
## See ?read.csv as you may need to change some switches
MyFile <- read.csv("C:\\Documents and Settings\\USER\\My
Documents\\MyFile.csv")
str(MyFile)
Without data it is difficult to help you further, but your general call to
discrimin.coa is
## This may or may not work; depends what's in MyFile
T.discrimin <- discrimin.coa(MyFile, fac = someFacInMyFile, scann=F, nf=4)
T.discrimin
plot(T.discrimin)
Regards, Mark.
