...30-39 0 1 40-49 2 1 50-59 2 1 60-69 0 1 Calling the function as: myfunc ("mydataset$ages, mydataset$sex") doesn't work either and nor does myfunc (c("mydataset$ages", "mydataset$sex")) Now in the simple version above I could make the function (category1, category2) and then call table (category1, category2) - but what if I might have a category 3, category 4 etc...

Then rsync runs the next night, notices the "new" image dir/category1/bar and does the huge image upload all over again, despite the remote system already having that image in dir/tmp/bar from the previous night. I need to make rsync use the existing file. Aha! Use link-dest! But...
