Im just attempt writing a function
which import manipulate and export spss data, my
basic problem when i use the cat command
that their is a space to much ?
Perhaps here exist a better solution ?
cat(paste(path),paste(file))
c:/Project/Allbus/ aprioriTotal.sav
test <- function(dir) {
for (i in 1:length(list.files))
path <- "c:/Project/Allbus/"
file <- list.files()[4]
tmpdata <-
read.spss(cat(paste(path),paste(file)),use.value.labels=F,to.data.frame=T)
thanks for advance
& regards,christian

read:
?paste
and use:
paste(path, file, sep="")

There is also file.path() for this purpose (and that allows you to write
paths without trailing separators, a good idea as Windows does not like
them).
But there is probably a yet easier way, as I suspect you intended
something like
test <- function(dir) {
for(fn in list.files(dir, full.names = TRUE)) {
tmpdata <- read.spss(fn, use.value.labels=F, to.data.frame=T)
....
}
}
