Your code relies on R's auto-printing, where each line of code executed
at the top level (not in loops or functions) is run as if it was
wrapped in print(...the rest of the line...).
Solution: make that print() explicit.
A better solution: explicitly pass the plot object returned by the
ggplot functions to the ggsave() function instead of relying on the
global state of the program.

When you type "c:/temp/f[i].jpg", what do you get in return?
Use paste0() or sprintf() to compose strings out of parts.
