It's a matter of environments:
your function makes "veri" for purposes of the function but then
throws it away when the function is done. If you want it to be
accessible you need to assign it to the global environment with
something like
assign("veri", read.transactions("c:/RVerileri/BitirmeVeri.csv",sep=";",col=1)
, envir = .GlobalEnv)
