Dear John,
I did just try to do that, and it is still returning the same error when I
try to attach the csv file..
vc1<-read.table("P:\\R\\Everything-I.csv",header=T, sep=" ", dec=".",
na.strings=NA, strip.white=T)
attach(vc1)
Error in attach(vc1) : variable names are limited to 256 bytes
Each variable name is only 5 to 6 characters long, but I'm sure you're
right about R reading the entire header line as one variable.
I cannot figure out though, how to stop it from doing so.
sep=" ", or sep="," do not seem to work either, though I don't know if it
is the right thing to be trying.

Well the first suspicious thing seems to be the 256 byte variable names.
Do you really have a 256 byte variable name? If so, why? It sounds like
R is reading the entire header line as one variable.
Why not try exporting the Exce file as a csv file and loading that?

Dear R users,
I am trying to read in a file with 105 columns, and when
trying to attach it, get an error as follows:
> vc1<-read.table("P:\\R\\Everything-I.txt",
header=T, sep=" ", dec=".",
na.strings=NA, strip.white=T)
> attach(vc1)
Error in attach(vc1) : variable names are limited to 256
bytes
Is there a way to get around this, and make R accept the
given variable names? Or will I have to shorten them?
Also, when I try to read in a much larger file with 430
columns, I get the error:
Error in scan(file, what, nmax, sep, dec, quote, skip,
nlines, na.strings, :
line 397 did not have 431 elements
Is it that R isn't dealing too well with
Excel-converted-to-text files? Is it a function of file
size?
I have double-checked the 430 column file and all data
seems to be in place.
Thanks for your help!
Aditi
