Hi,
I am using the scan function to read from a file. In
general the syntax I am using is as follows:
scan("myfile", list(a = "", b="", c="",
d=""), sep=",")
The file I am trying to read contains a #< in the 'd'
field. When the file is read into an object, the d
field comes as "" for that particular string.
I guess the problem is because the # is used for
commenting.
My question is that if I want to read the #< anyways
from the file, how do I do that?
Thanks in advance.
-Saket.

Hello, it looks you using R1.4.X in this case you have to add comment.char = "" to your scan command, because '#' is used to mark comments. In R1.5.0 "" is the default (that means: no comments allowed), which is the better option beacause there are many different comment chars in tht different file types. gruess joerg joshi at engr.orst.edu wrote:> > Hi, > > I am using the scan function to read from a file.
