Because you re-assign the Phase1 variable in the for loop. At the end of the
loop it has the value you set during the last iteration, i.e. LRPhase==1 since
you used c(-1,1) in the code (and not c(1,-1) as in your question).
Try
for (LRPhase in c(-1,1)) {
Phase1<- output[output[,2]==LRPhase,]
Phase1<- Phase1[order (Phase1[,6]),]
print(Phase1)
}
Hope this helps a little
