Hi, I have a simple beginner's question on removing a list of objects. Say I have objects C243.Daily1, C243.Daily2...C243.Daily5 in my workspace. I'd like to remove these without using rm five times. So I write. > a <- list(paste("C243.Daily",sep="",1:5)) > rm(a) Obviously this wouldn't work, as it would only remove the object a. But is there any way

Hi R Gurus! I'm trying to create a test package using the package.skeleton function. I wanted to add some compiled code too. In the src library, I put together a baby subroutine, compiled it and created a test.dll When I use the R cmd build, it works fine. But I get into trouble with the R CMD check section. /home/Desktop/R-2.5.1/bin # ./R CMD check mypkg * checking for working latex ...
