Dear Sirs,
I am just starting with R and I think it is a great system. Now, I
want to
import Stata datasets (.dta) with read.dta, but receive errormessages
like:
Error in grep("^(http|ftp|https)://", file) : object "Rklein" not found
Error in read.dta("Rklein") :
unable to open file: 'No such file or directory'
this happens when I use ""
What is the problem and how can I solve it?
Hi Rob,
Looks like you're on Windows, and you have probably fallen victim to the
Microsoft (and Apple) "hide-everything-you-can-from-them" file manager
defaults. Your file "Rklein" probably has an extension on it (maybe
.dta?) and if you can find that by turning off extension hiding, you
will probably see the solution immediately.

Also, notice the function choose.file() which lets browse your way to
The function name is actually file.choose(), which exists on all (?)
platforms. There's also a function choose.files(), only on Windows, and
mainly used for choosing multiple files (but it has a few other
Windows-only differences from file.choose()).

the file in the usual Windows style. If used on its own, then it returns
the full path to the file, so that you know what to feed to read.dta().
You can short-circuit by using read.dta(choose.file()), but if you do it
in a script, then you need to do the browsing every time you run the
script.
