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?
It's my guess that you have an unmatched quote in your header
somewhere. The error is reported when the length of a SINGLE variable
name is over the 256 character limit, and not when the total number of
characters in all of the variable names is over 256. Shirley, you
cannot have a variable name that want to be that long.
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?
R is not the problem. It is capable of "filling".
I have double-checked the 430 column file and all data seems to be
in place.
Again, probably a misplaced quote character.
