 R will only look in the current working directory if you don't
specify a full path to read.table. That's the directory you start R
from, or any directory set with setwd("some/path") in an R session.
Suggest you get hunting for your data set...

 You get that if you mistakenly try subsetting a function. I suspect
this is because you try to call your data 'data' and that gets
confused with the data function because the read.table fails. If you
start a fresh R session and do:

 data$something

 you'll get that message.

 R is smart enough though, that if you do create a data frame with the
name 'data' it will go for that if you do data$something...
