Help w/an old R program I've rediscovered and want to make work

I found an old R program I wrote som eyears back and I'd like to make work in
2.11.1 (or a more recent version), but am having two problems:

1. I can't seem to access the datafile it requires. I'm not sure where the
default place that R looks to for files references within it is, or what
exactly the format is for pulling in the data, by my own #comments from a
few years ago aren't helpful.

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...

2. Whether or not it's related to the problem locating the data file, the
error message I get is:

"object of type 'closure' is not subsettable"

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...
