length_octave: Length of R objects (GNU Octave/MATLAB compatible)

In iemisc: Irucka Embry's Miscellaneous Functions

Length of R objects (GNU Octave/MATLAB compatible)

Description

Obtain the length of R objects [arrays, matrices, and vectors (including lists)] in a manner compatible with GNU Octave/MATLAB. Some documentation from length.

Usage

length_octave(x)

Arguments

x	An R object (array, matrix, vector)

Value

Return the length of the object x as an integer. "The length is 0 for empty objects, 1 for scalars (in R, a vector of length 1), and the number of elements (in R, the length) for vectors. For matrix objects, the length is the number of rows or columns, whichever is greater (this odd definition is used for compatibility with MATLAB)." Source: Eaton.
