Does this happen only in RStudio?  She can run `pdf("somefile.pdf")` 
before plotting and `dev.off()` after to save the results to a PDF file 
instead.  If the problem only occurs in RStudio, then you should 
probably contact Posit or one of their community support groups about it.

If it happens in other devices too:  is she using base graphics, or 
ggplot2, or something else?  If she's using base graphics, take a look 
at `par("mar")`.  That gives the size of the margins measured in lines 
of text; they are in the order bottom, left, top, right, with default 
value `c(5.1, 4.1, 4.1, 2.1)`.  Perhaps she has set the 2nd entry to zero.

I'm sure there's something similar in ggplot2 and other graphics 
systems, but I don't know what it would be.
