attend

[gpiras]

Hi Justin, from some reason there is a problem when trying to subset() the attend data by priGPA. Here are
some details.

It seems to work fine as long as priGPA is an integer:

subset(attend, priGPA == 3 & ACT == 21)
attend termGPA priGPA ACT final atndrte hwrte frosh soph missed
512 30 3.38 3 21 16 93.75 100 0 1 2
643 30 3.25 3 21 27 93.75 100 1 0 2
645 32 3.04 3 21 28 100.00 100 0 1 0
stndfnl
512 -2.0483193
643 0.2626050
645 0.4726891

However, if priGPA has decimals, the subsetting doesn't work properly:

subset(attend, priGPA == 3.65 & ACT == 20)
[1] attend termGPA priGPA ACT final atndrte hwrte frosh
[9] soph missed stndfnl
<0 rows> (or 0-length row.names)
