I have a string like this st <- "SELECT COUNT(empid), COUNT(mgrid), COUNT(empname), COUNT(salary), FROM Employees" How can I remove the last comma before the FROM statement?
This doesn't use a regex, per se, but:
st <- "SELECT COUNT(empid), COUNT(mgrid), COUNT(empname), COUNT(salary), FROM Employees" st
[1] "SELECT COUNT(empid), COUNT(mgrid), COUNT(empname), COUNT(salary), FROM Employees"
sub(", FROM", " FROM", st)
[1] "SELECT COUNT(empid), COUNT(mgrid), COUNT(empname), COUNT(salary) FROM Employees"
I'm not sure that's what you had in mind, though. Peace, david
