[R] reading in tab delimited data in a loop

[Edmond Ng]

Dear all, 

I need to read in 4 sets of tab delimited data in a  loop. The 4 data sets are called "simu1.dat", "simu2.dat" and so on. I know what I need on the righthand side of the read.table expression but I can't the left hand side of it to work (see the line in bold below). Can you kindly help? Many thanks. 

simu1 <- matrix(0,30,3)
simu2 <- matrix(0,30,3)
simu3 <- matrix(0,30,3)
simu4 <- matrix(0,30,3)

for (i in 1:4) {
simu[i] <- read.table( paste("simu",i,".dat",sep="") )
}
