length(Sys.glob(file.path(Dir, "*.pdf)))
or use the 'pattern' argument of list.files()
or use system(paste("ls", file.path(Dir, "*.pdf), "| wc -l"), intern=TRUE)

Hi
Lets say,
Dir<-"/var/www/html/celnet/users/cxadmin/FlowDuration_DataVolume/fld_01_
08_18_08"
There will be pdf and/or csv files.
I want to know how many *.pdf files are there in that
directory.
How can I get using R commands.
Thanks
