I often need to determine the span of the x-variable in a graphic.
This is easy to determine with:
diff(range(VAR, na.rm=T))
I am not aware of any function in base R that accomplishes this and “span” is
not taken.
Then you should write one that suits your needs. It could have just the
line above, or you could make it fancier, expanding the range a bit like
plot() does.
Would it be possible to add such a function? Not a major addition but often
useful.
If you think others would like to use it, then include it in a package
and publish the package.
