[R] Simple question about Lists

[Gabor Grothendieck]

Try this:

> L <- list(matrix(1:10, 10))
> L
[[1]]
      [,1]
 [1,]    1
 [2,]    2
 [3,]    3
 [4,]    4
 [5,]    5
 [6,]    6
 [7,]    7
 [8,]    8
 [9,]    9
[10,]   10

> plot(L[[1]])


If your object is somehow different then please display it like this:

   dput(x, control = "all")

where x is your object so we can reproduce it exactly.
