[R] ggsave() with width only

[Ivan Calandra]

Yes Jeff, you are right. I hate manually editing figures too, but 
sometimes I find it's still the easiest way (e.g. when you submit your 
paper several times when journals have differing guidelines, or when you 
build figures from several (sub)plots + other images, or when you 
combine plots that a colleague has done in Python with your R plots). I 
have the impression that at some point, there is always something to 
edit by hand, no matter how much you've adjusted the graphical 
parameters and even if you use all possible tools available for ggplot2...

I have thought a lot about it and, as it is, I am not sure it would be 
worth the effort. I might be missing some arguments for it, but I would 
actually like someone to show me how it could look like - this might 
just be what I need to be convinced!

But sometimes you get stuck in an approach... I cannot answer your original post, but wanted to point out that it may not actually be necessary to answer it if you change your approach.

>>> I use an rmarkdown file to generate consistent output figures and tables for html or Word. I just use Rnw files directly if I am generating LaTeX. I do not use R files for building output... and I never use ggsave. So you might consider altering your approach to bypass the question entirely.
