Furthermore, aggregate passes extra arguments to FUN, so explicit declaration of na.rm = T can be done in the call to aggregate directly: aggregate(cbind(v1, v2) ~ v3, data = testDF, FUN = mean, na.rm = T) HTH, Jon On Tue, May...

I have some suggestions inline below. My biggest suggestion would be to read the help files that came with R, especially the section "Invoking R" in "An Introduction to R". On Thu, May 12, 2011 at 10:24 AM, Bazman76...

In python, opening a connection using with allows for a temporary assignment using "as". So: with file("/path/to/file") as con: permanent_object = function(con) would provide the return of function(con) globally, but close con. If function(con...

myR.bat is a microsoft batch file, meant to be run from the windows command line. If you are in R, you can run R files using a single command. Please try reading the Introduction to R that ships with...

So TreeAge fits models but won't predict from them? That seems like bizarre behavior. I suppose I would recommend, then, looking at the source code from the aforementioned packages for how they store their split data. It sounds like...

I cc'd r-help to get this message back on the board. Again, you haven't really answered my questions. Comments inline. On Thu, May 19, 2011 at 9:45 AM, chirine wolley <wolley.chirine at hotmail.com> wrote...

What do you mean when you say "wrong results"? What do you expect for the output? Your code doesn't work for me because it references X in places and X is not defined. Have you tested your functions to...
