I want to create a matrix from character vector similar to:

comments <- c("abc", "lol")
comm_matrix <- matrix(data=comments, ncol=3, nrow=1)

I want to get matrix, but with NA if ncol > nchar in vector:

[,1] [,2] [,3]
abc  lol  NA

Instead of default:

[,1] [,2] [,3]
abc  lol  abc

Thank's mates, the solution is:

comments <- c("abc", "lol")
length(comments) <-prod(dim(matrix(comments, ncol=3)))
comm_matrix <- matrix(data=comments, ncol=3, nrow=1, byrow=TRUE)
comm_matrix

#    [,1]  [,2]  [,3]
#[1,] "abc" "lol" NA
