I have a data frame in wide format. There are six variables that represent two
factors in long format 3x2, Valence and Temperature:
> head(dpts)
File Subj Time Group PainNeg.hot PainNeg.warm SociNeg.hot
SociNeg.warm Positiv.hot Positiv.warm Errors
1 WB101_1_1_dp.txt 101 1 MNP 30.700000 13.75000 16.319048
35.166667 30.18333 14.383333 1
2 WB101_2_1_dp.txt 101 2 MNP 5.266667 -79.60000 -24.738095
-5.500000 23.95000 -14.700000 0
3 WB102_1_1_dp.txt 102 1 MNP 50.750000 -13.43214 5.185714
19.083333 4.20000 -8.033333 1
4 WB102_2_1_dp.txt 102 2 MNP -41.383333 9.32500 -9.845238
22.950000 -14.35000 40.933333 0
5 WB103_1_1_dp.txt 103 1 MNP 25.266667 -48.27500 48.726190
8.141667 10.98333 -31.966667 2
6 WB103_2_1_dp.txt 103 2 MNP 26.750000 -13.28929 3.447619
-8.641667 -10.90000 -27.416667 1
The following command does part of what I want:
dptsr<-reshape(dpts,
varying=c('PainNeg.hot','PainNeg.warm','SociNeg.hot','SociNeg.warm','Positiv.hot','Positiv.warm'),
v.names=c('Bias'),direction='long',timevar=c('Valence','Temperature'),
times=c('PainNeg.hot','PainNeg.warm','SociNeg.hot','SociNeg.warm','Positiv.hot','Positiv.warm'),
idvar=c('Subj','Time'))
But it doesn't break out the two factors:
> head(dptsr)
File Subj Time Group Errors Valence
Temperature Bias
101.1.PainNeg.hot WB101_1_1_dp.txt 101 1 MNP 1 PainNeg.hot
PainNeg.hot 30.700000
101.2.PainNeg.hot WB101_2_1_dp.txt 101 2 MNP 0 PainNeg.hot
PainNeg.hot 5.266667
102.1.PainNeg.hot WB102_1_1_dp.txt 102 1 MNP 1 PainNeg.hot
PainNeg.hot 50.750000
102.2.PainNeg.hot WB102_2_1_dp.txt 102 2 MNP 0 PainNeg.hot
PainNeg.hot -41.383333
103.1.PainNeg.hot WB103_1_1_dp.txt 103 1 MNP 2 PainNeg.hot
PainNeg.hot 25.266667
103.2.PainNeg.hot WB103_2_1_dp.txt 103 2 MNP 1 PainNeg.hot
PainNeg.hot 26.750000
So I did successfully create two factor variables, but they both contain the
same values. Instead I would want "Valence" to be (for example) "PainNeg" and
"Temperature" to be "hot".
Can anyone help me figure out how to get reshape to do this? I have never been
able to make much sense out of the reshape documentation...
Thanks!

A neuroscientist is at the video arcade, when someone makes him a $1000 bet
on Pac-Man. He smiles, gets out his screwdriver and takes apart the Pac-Man
game. Everyone says "What are you doing?" The neuroscientist says "Well,
since we all know that Pac-Man is based on electric signals traveling
through these circuits, obviously I can understand it better than the other
guy by going straight to the source!"
