[R] Performance

[Francisco do Nascimento Junior]

Hello,
I'm applying an arithmetical function the color (R,G,B) of each
pixel of a figure and it's very slow. This is common?
Other thing, are there some library to make modification in figures, eg,
to alter size?
If not, somebody knows some software that makes this, or either, to
resize figures automatically, therefore I go to need to apply to a bank.

Tks,
Francisco.
