I haven't used R in a couple of years, and now am trying something as simple as importing a csv file and am running into problems right away. * mydata <- read.csv (Wordata1.csv, sep="") Error in read.table(file = file, header = header, sep = sep, quote = quote, : object 'Wordata1.csv' not found *I've tried in both as as read.csv and read.table and still get the same message. I've double-checked that I'm in the right directory using "getwd()" and indeed I am. Any ideas on what might be causing this error message? Can it be something in the format of the file? (I've looked through the archives and didn't see anything that might explain it) thank you!!! Alina [[alternative HTML version deleted]]
You probably left off the quotes for the file name
mydata <- read.csv ("Wordata1.csv", sep="")
it is looking for an R variable named Wordata1.csv which contains the name
of the file.
Since you are giving it the name of the file, it must be in a
character-valued constant.

R is looking for an R object named Wordata1.csv that contains your file name.
Instead you want:
mydata <- read.csv ("Wordata1.csv", sep="")

Try quoting the file name (assuming such a named file is in your working directory.) It also doesn't make much sense and may even be an error to supply a sep="" argument to read.csv().> (I've looked through the archives and didn't see anything that might > explain > it)Well, there are surely examples where questioners have been told they needed to quote the 'file' argument, but there might be many other errors that created an invalid argument. -- David Winsemius, MD West Hartford, CT
