DIM {listarrays} | R Documentation |
Helpers for working with 1-d arrays
Description
DIM()
is to dim()
as NROW()
is to nrow()
. That is, it is identical to
dim()
in most cases except if the input is a bare atomic vector with no
dim
attribute, in which case, the length of the vector is returned instead
of NULL
.
DROP
first calls base::drop
and then completely removes the dim
attribute if the result is a 1-d array
Usage
DIM(x)
DROP(x)
Arguments
x |
an R vector, potentially with a dim attribute |
Value
For DIM
, the dim
attribute, or if that's not found, then length(x)
For DROP
an array with 2 or more axes, or a vector with no dim
attributes.
Examples
x <- 1:3
dim(x)
dim(array(x))
DIM(x)
DIM(array(x))
x <- array(1:3)
str(drop(x))
str(DROP(x))
