Look in current project files

If I install the development version and then:

> pedant::add_double_colons()
Error in pedant::add_double_colons() : {rstudioapi} must be installed

What I would hope would happen here is pedant would look at all R-like files such as .R, .Rmd etc, but seemingly the only two ways it accesses your files is either using the Rstudio API and grabbing the selection, or by passing in the text directly to a function which I don't see as an actual practical use case since you would then have to copy the output from the R terminal into your code.

Yeah, I kind of felt that the code argument was of limited use when I was implementing it but wasn't sure what to do about it, this is a good suggestion though. How about a new files argument which would include pattern-support and give the following behaviour:

• If the code argument is specified then run on that code (though this isn't that useful)
• Otherwise, if the files argument is specified then run on those files
• Otherwise, if rstudioapi is installed and there is code selected then run on the selected code
• Otherwise, run on all files in the working directory after asking for confirmation

Actually I would kind of be in favour of separating these functions out, since they have different inputs and outputs, so it doesn't necessarily make sense to treat them as the same.

e.g.

• style_character: character argument → returns character
• style_pkg: no parameters → styles files in the current package/directory as side effect
• style_rstudio: no parameters → edits selection as side effect

You could make an argument about combining these last two since they have no inputs or outputs, but the rstudio mode has the issue of having an extra requirement.

Also for what it's worth you can probably be clever about choosing the files to style, along the same lines as styler.

Another very nice suggestion! Thanks very much, I may well use this approach. Quite busy with other things but planning to make some changes to pedant when I can and then submit to CRAN. I'll come back to this issue when I've made some progress :)
