Surprising: must be newer update than I realized....anyways, here's
the code if you want to add it manually:
simplify2array <-
function (x, higher = TRUE)
{
if (length(common.len <- unique(unlist(lapply(x, length)))) >
1L)
return(x)
if (common.len == 1L)
unlist(x, recursive = FALSE)
else if (common.len > 1L) {
n <- length(x)
r <- as.vector(unlist(x, recursive = FALSE))
if (higher && length(c.dim <- unique(lapply(x, dim))) ==
1 && is.numeric(c.dim <- c.dim[[1L]]) && prod(d <- c(c.dim,
n)) == length(r)) {
iN1 <- is.null(n1 <- dimnames(x[[1L]]))
n2 <- names(x)
dnam <- if (!(iN1 && is.null(n2)))
c(if (iN1) rep.int(list(n1), length(c.dim)) else n1,
list(n2))
array(r, dim = d, dimnames = dnam)
}
else if (prod(d <- c(common.len, n)) == length(r))
array(r, dim = d, dimnames = if (!(is.null(n1 <- names(x[[1L]])) &
is.null(n2 <- names(x))))
list(n1, n2))
else x
}
else x
}
