The dimension of a vector or matrix or a data frame

Description

Returns the dimension (i.e., number of columns) of x, which is a matrix or a vector or a data frame. This is different than the dim function in base R, in the sense that, dimension gives only the number of columns of the argument x, while dim gives the number of rows and columns of x. dimension also works for a scalar or a vector, while dim yields NULL for such arguments.

Usage

dimension(x)

Arguments

x	A vector or a matrix or a data frame whose dimension is to be determined.

Value

Dimension (i.e., number of columns) of x
