Dear Brendan,
One way could be either
bigt <- sapply(1:10,function(x) rnorm(250))
colnames(bigt) <- paste('t',1:10,sep="")
bigt
or
bigt2 <- NULL
for(i in 1:10) bigt2 <- cbind( bigt2, rnorm(250) )
colnames(bigt2) <- paste('t',1:10,sep="")
bigt2
or
bigt3 <- matrix(rnorm(250*10),ncol=10)
colnames(bigt3) <- paste('t',1:10,sep="")
bigt3
HTH,
Jorge
