[R] reading in tab delimited data in a loop

[Liaw, Andy]

There's no bold face in plain text.  I assume it's the line inside the loop
that's giving you trouble.

Two approaches:

1. for(i in 1:4) assign(paste("simu", i, sep=""), read.table(...))

2. simu <- vector(4, mode="list")
   for(i in 1:4) simu[[i]] <- read.table(...)
