For bivariate kernels there is kde2d in MASS kde2d.g in GRASS KernSur in GenKern (list probably incomplete) but none of them seems to accept a weight parameter (like density does since R 2.2.0) -- Erich Neuwirth, University of Vienna Faculty of Computer Science Computer Supported Didactics Working Group Visit our SunSITE at

Hi Everyone, I want to get the commands history as a character vector instead of just displaying them, but the function history() just returns NULL. I checked the source code of 'history' and could not find a solution. Anybody has an idea? Thanks! P. S. My original problem is, when a user opens a graphics device like png() or pdf(), I want to know the file name used by this device. I

I just uninstalled R 2.7.2 on Windows XP after having installed R 2.8.0 The uninstaller removed the String values HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\Current Version HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\InstallPath despite the fact that they pointed to R 2.8.0 The uninstaller did not remove the key HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\2.7.2 (and all the values in that key) I think the

Up to now I've used write.csv(), but I have to resave every file in .xls in Excel. I would like to know if there is a function or package to export directly into *.xls.

I do not know if this has been reported already (I searched the headers of the recent messages to r-devel) It seems that 'example' in R 2.11.0 has a problem when the help file does not contain any example.

I am running R as an invisible subprocess in another program (RExcel). Using try I can catch errors and print the errors produced by an R statement. Is there a way to know if running a statement caused a warning message? last.warning gives me the last warning, but I do not have any indication what the statement was that caused the message. I can of course store last warning before I run a

Hi, this is Charlie. I have installed the Rpad on my server (using Fedora Core 6 with httpd2.24-2, mod_perl 2.0.2-6.1, perl 5.8.8 from RPM).

And when I do ?HTML R tells me that HTML shows up in to places, Rpad
