Those functions will end up in each working directory you use. Unless
you have only a small number of those functions, that will produce a
lot of unnecessary duplication. You can avoid that by saving those
functions in a .RData type file, and then something like:
attach("/path/to/file/.RData")
There's no need for a .First file. Having that line in your .Rprofile
will be sufficient.
It would be tidier to make them into a package, but the above will
work easily enough.
