attend
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)
Here is my session info:
