How to save a function as new R script?

Question

Given a function, how to save it to an R script (.R)?

Save works well with data, but apparently can not create .R data.

Copy pasting from the console to a new script file appears to introduce characters that cause errors.

Answer 1

I have to ask: why are you writing your functions in the console in the first place? Any number of editors support a "source" call, so you can update the function as you edit. Copy/pasting from the console will carry prompt characters along , if nothing else, so it's a bad idea to begin with.

Answer 2

Take a look at the dump function. That writes files that are R code that can be read back in with source or used in some other way.
