My memory is getting clogged by a bunch of intermediate files (call them temp1
, temp2
, etc.). and I would like to know if it is possible to remove them from memory without doing repeated rm
calls (i.e. rm(temp1)
, rm(temp2)
)?
I tried rm(list(temp1, temp2, etc.))
, but that doesn't seem to work.
This question is related to
r
An other solution rm(list=ls(pattern="temp"))
, remove all objects matching the pattern.
Another variation you can try is(expanding @mnel's answer) if you have many temp'x'.
here "n" could be the number of temp variables present
rm(list = c(paste("temp",c(1:n),sep="")))
Or using regular expressions
"rmlike" <- function(...) {
names <- sapply(
match.call(expand.dots = FALSE)$..., as.character)
names = paste(names,collapse="|")
Vars <- ls(1)
r <- Vars[grep(paste("^(",names,").*",sep=""),Vars)]
rm(list=r,pos=1)
}
rmlike(temp)
