R help - Jul 2004 - (no subject)

Hello,
            I'm new to R, and I'm having trouble importing a text file
(I'm
on Windows XP)
 
>  m <- read.table("/Desktop/work/128_L")
Error in file(file, "r") : unable to open connection
In addition: Warning message: 
cannot open file `/Desktop/work/128_L'
 
 
do you know why this isn't working?  All I have is a bunch of text files,
each with a single column of about 30,000 rows.
 
thanks

Hello!

It just is not able to find the file as the error message says.
You can check if you are specified the right directory path using dir.

?dir

dir("/Desktop/work/")

I gues you are not.

If you are specifying the full path, precede it with the drive name c:/

Dear David,

You got several useful suggestions for what you may have done wrong. I often
find that it's easier to use read.table(file.choose()) and to navigate to
the file in the resulting dialog than to type the path to the file.

I hope that this helps,
 John
