Negative. It has nothing to do with brevity of sending.
CW ops use “R” for a decimal because it’s been considered as such for at least a hundred years, and because a period is intellectually different from a decimal (though visually they look the same when written). Periods connote the end of sentences, initials, and abbreviations. Periods (not decimals) are also used in email addresses.
When used in a context of numbers, an “R” nearly always connotes a decimal point. One exception, however, would be a serial or part number comprised of a context of both numbers and letters in which case an “R” would connote an “R” (it being the case that serial numbers and part numbers seldom (if ever) contain a decimal point.
See W1AW’s orbital bulletins for long-standing examples.
