Hi there,
I have a list of filenames like
a<-c("file1.dbf", "file32.dbf", "myfile_temp.dbf")
and I would like to remove the ".dbf" string from all records and obtain
somethink like
file1
file32
myfile_temp
Thanks in advance,

As is usually the case with R, there are several approaches:
> sub("\\.dbf", "", a)
[1] "file1" "file32" "myfile_temp"
> sapply(strsplit(a, "\\."), "[", 1)
[1] "file1" "file32" "myfile_temp"
> substr(a, 1, nchar(a) - 4)
[1] "file1" "file32" "myfile_temp"
My personal preference would be the first.
See ?sub, ?strsplit, ?sapply, ?substr and ?nchar for more information.
As an aside, if you should need to manipulate complete file paths to
extract the file name, see ?basename
