Dear Gheine,
you could also start creating your own package with these functions, and
manage the code using R's well thought-out package management
functionalities, with namespaces etc. At some point, this might be less
effort than (re-)inventing tools as below.
Best wishes

for(nm in ls(all = TRUE)) if (is.function(get(nm))) assign(nm,

# usage:
src("myfile.R")

Working with a number of scripts (text files with R commands) that I
"source" into R sessions from time to time.
The source() command is most convenient (at least for me)
if it only loads function definitions, and doesn't otherwise change the
interactive environment. For example, I might have a file that looks like
func1<-function() {
code
code
code
}
# this is a comment
A<-"this is code outside the function definitions";
func2<-function() {
code
# a comment with a spurious }
code
code
}
I would like a quick-and-dirty script that finds the line beginnning with
"A", since it is R code outside of any function definition.
On the other hand it would ignore the two comment lines, and would not be
fooled by the spurious "}" in the second comment line.
Probably not too hard to put something like this together, but am making
this post in case it is something that has already been done.
Thanks!
