Displays all values of a matrix of vectors by “unrolling” the object vertically or horizontally.
unroll(x, bycol = FALSE, drop = TRUE)a list of vectors with a dim attribute of
length 0, 1 or 2.
logical; whether to unroll horizontally
(FALSE) or vertically (TRUE).
logical; if TRUE, the result is coerced to the
lowest possible dimension.
A vector or matrix.
unroll returns a matrix where elements of x
are concatenated (“unrolled”) by row (bycol = FALSE) or
by column (bycol = TRUE). NA is used to make
rows/columns of equal length.
Vectors and one dimensional arrays are coerced to row matrices.
This function was originally written for use in
severity.portfolio.
# NOT RUN {
x <- list(c(1:3), c(1:8), c(1:4), c(1:3))
(mat <- matrix(x, 2, 2))
unroll(mat)
unroll(mat, bycol = TRUE)
unroll(mat[1, ])
unroll(mat[1, ], drop = FALSE)
# }
