[R] Reducing the "dimension" of a list object

[Bogaso]

Please consider following code :

set.seed(1)
res <- vector("list")
for (i in 1:5) {
   res1 <- vector("list")
   res1[[1]] <- letters[1:5]
   res1[[2]] <- rnorm(5)
   res1[[3]] <- rnorm(5); res[[i]] <- res1 }
res[[1]]

# Now I want to reduce the dimension of "res" through creating a data frame
like that
mat <- data.frame(nrow=5, ncol=2)
for (i in 1:5) {
   mat[i,1] <- res[[i]][[1]][1]
   mat[i,2] <- res[[i]][[2]][1] }; mat

Here I am looking for more "efficient" code by avoiding the loop. Is there
any smart way to do that ?

Thanks,
