If your working directory contains a file you want to read then the following should work: dat - read.table(filename.txt) If you want to use absolute paths, you have to be careful with the '\' because that is an escape character... so try: dat - read.table(c:/some/path/notice/forward/slashes/data.txt) # or dat - read.table(c:\\double\\back\\should\\work\\data.txt) On Thu, Jan 29, 2004 at 09:19:23AM -0700, [EMAIL PROTECTED] wrote: hello there, I'm a new user to R and I am having difficulty reading a file into the program.

I must have done something wrong. I'm surprised that it didn't work with the full path. I assume the error message indicated that it could not find the file, as opposed to some other sort of error. Relative paths work too. You don't say what operating system you are using, and it probably matters. But on Linux/Unix I usually start R from the directory where the data files are, and I have several of these for different projects. (Actually I use ESS, so I start R from within (X)emacs. When I say alt-x, R, I'm asked for a directory, and, if I'm not already in that directory, I enter it using a relative path name.) In sum, at least in Unix/Linux, you can put your data anywhere, and either you start R from where the data are or you use a relative or full path name. 2) is it possible to create a data file in R instead of put data in a txt file and then save the file under R? Yes, but this isn't the best way to do things unless the data file is pretty small. You can use c(). It is sometimes helpful to use matrix() with the argument horiz=T as in Example 2 in Advanced analysis of variance examples in http://www.psych.upenn.edu/~baron/rpsych/rpsych.html See also scan() - that is, look at the help for it. And you can also use edit(). For example: m1 - matrix(0,5,5) m2 - edit(m1) To save the object you've created, use write(), write.table(), write.matrix(), dput(), or save(). These differ in formatting and in how you read it back in.
