Hello Alessandro,

may I suggest to use list.files() {base} function to pick up the files?

the code would look like:

files <- list.files(getwd(), pattern="vegetation")
for (i in files) {
# extract coordinates
coordinates(file=i, =~X+Y)
# write as shapefile
writeOGR(obj=i, <other options>, driver="ESRI Shapefile"))

hope this helps
