[R] Does this exist: diff(range(VAR, na.rm=T))

[Ben Bolker]

   Not speaking for R-core, but the general answer to "could we include 
this simple helper function in base R?" is "no, put it in a package or 
in your own set of source()d helper functions; if it turns out to be 
incredibly useful we might add it somewhere down the line".

    You could ask to have it added to the `gtools` package, which has 
been around for a while and has no strong dependencies ...
