rray (version 0.1.0)

rray_max_pos: Locate the position of the maximum value

Description

rray_max_pos() returns the integer position of the maximum value over an axis.

Usage

rray_max_pos(x, axis = NULL)

Arguments

x

A vector, matrix, array, or rray.

axis

A single integer specifying the axis to compute along. 1 computes along rows, reducing the number of rows to 1. 2 does the same, but along columns, and so on for higher dimensions. The default of NULL first flattens x to 1-D.

Value

An integer object of the same type and shape as x, except along axis, which has been reduced to size 1.

Examples

# NOT RUN {
x <- rray(c(1:10, 20:11), dim = c(5, 2, 2))

# Find the max position over all of x
rray_max_pos(x)

# Compute along the rows
rray_max_pos(x, 1)

# Compute along the columns
rray_max_pos(x, 2)

# }
