Hello all,
I'm trying to create a 2x2 matrix, 32 times after unlist() so that I can
convert the list to matrix. I've looked through the R archive but
couldn't find the answer. There is what I've done.
> f <- system("ls *.txt", intern=TRUE)
> x <- lapply(f, read.table)
> x
[[1]]

The output should be

[,1] [,2]
[1,] 14.4 29.0

[[3]]
[,1] [,2]
[1,] 29.0 -38.1
[2,] -3.4 55.1
...
Thanks and much appreciated!
