Nancy,
You really should read the help page for read.csv.
Try this
test <- read.csv2("testset.txt")
Note the '2'.

Hi all,
Thanks for the explanation
I got other datasets that are already used with others but I got the same
errors:
“undefined columns selected”
I attach the datasets with this email and this is the command I’m trying:
train = read.csv("trainingset.txt",check.names=FALSE)
test = read.csv("testset.txt",check.names=FALSE)
many thanks,
Nancy
