The formatR package can do the trick based on the parser package, e.g.
tidy.source(text = 'x=1;plot(x=1:10)', replace.assign = TRUE)
## you get this:
## x <- 1
## plot(x = 1:10)
The first argument of tidy.source() can be the file path of your script.
BTW, it is good to know I'm not the only one who insists on using =
instead of <-. Please say hello to him/her for me :)
