[R] RegExpr: Help match quote inside a set

[Bert Gunter]

Yes. From ?regex
"A range of characters may be specified by giving the first and last
characters, separated by a hyphen. (Because their interpretation is locale-
and implementation-dependent, character ranges are best avoided.) "

Although it is terse, if you have not already done so, you should read
?regex carefully. I'm a dummy but have found it very helpful.
