Replace multiple values in a list in R

Question

If I have:

mylist <- lapply(1:10, function(x) matrix(NA, nrow=2, ncol=2))

And I want to replace, for example, the first, second and fifth element in the list with a:

mymatrix=cbind(c(1,1),c(1,1))

What can I do? I tried with:

mylist[c(1,2,5)]=mymatrix

But I can't substitute the new matrix because it's another list and with the [[]] I can only access to one element.

I think I have to use the lapply function but I can't figure out in which way.

Answer 1

Would this work for you?

mylist[c(1, 2, 5)] <- lapply(mylist[c(1, 2, 5)], function(x) x <- mymatrix)
