drop
Drop Length One Dimensions of an Array

### Description

Returns an array or a vector, deleting dimensions that have only one level (dead dimensions).

### Usage

    drop(x)

### Arguments

x | any object, but anything other than a matrix or array is simply returned unchanged.

### Details

Dead dimensions are dropped automatically when arrays are subscripted, unless you use drop=FALSE. (See Subscript).
Value
returns an array with the same values as x, except that dead dimensions are dropped. That is, all ones in dim(x) are deleted, and dimnames(x) is adjusted appropriately.
Returns a vector if all dimensions are dropped, or if x has no dimensions.

Subscript, array, matrix.
Examples

    # if x is an n by 1 matrix, with n large, you
    #    can look at it more easily with
    x <- matrix(1:10)
    drop(x)
