typeof applied to a factor always seems to return "integer", independently of the type of the levels. This has a strange side effect. When a variable is "imported" into a data frame, its type changes. character variables automatically are converted to factors when imported into data frames. Here is an example: > v1<-1:3 >

In some languages there is a function gensym() which returns a new unique name (in the current environment). This is quite helpful when one has to do temporary assignments. I could not find such a function in R.

It would be convenient to have something like Rgui runfist="myfunction()" in Windows. The reason: AFAIK Rgui does not accept piped input (RGui < myfile.R does not seem to work). A solution could be to put a few fuctions in Rprofile and then give the name for one of these functions to be executed at startup as a command line parameter to Rgui. Can something like this be done? --

Hi, I'm trying to combine a VBA macro and a R package. I've installed the R-(D)COM and the R-excel interface by Neuwirth. They seem to work both. However I would like to display the r-generated data in an Excel sheet as an array but I don't manage.
