Thanks Arun and Jim; this helps me sort out several points I hadn't been
aware of! -David

Hi David,
Try:
Check the output of:
lapply(mm,function(x) x) #mm is matrix
#and
lapply(as.data.frame(mm),function(x) x)
sapply(split(mm,col(mm)),function(x){out <-
t.test(x[1:15],x[16:25])$p.value})
# 1 2
#0.1091573 1.000
#or
sapply(as.data.frame(mm), function(x)
