[Dan Abner]

Hi everyone,

What is the easiest way to remove the word Average and strip leading
and trailing blanks from the character vector (d5.Region) below?

.nrow.d5.           d5.Region
1            1     Central Average
2            2     Coastal Average
3            3        East Average
4            4  Metro East Average
5            5 Metro North Average
6            6 Metro South Average
7            7  Metro West Average
8            8   Northeast Average
9            9   Northwest Average


Thanks!

Dan
