R: Bin-count matrix data

binCount2D {oce} | R Documentation

## Bin-count matrix data

### Description

Count the number of elements of a given matrix z=z(x,y) that fall within successive pairs of breaks in x and y.

### Usage

    binCount2D(x, y, xbreaks, ybreaks, flatten = FALSE)

### Arguments

`x` | Vector of numerical values.
`y` | Vector of numerical values.
`xbreaks` | Vector of values of `x` at the boundaries between bins, calculated using `pretty(x)` if not supplied.
`ybreaks` | Vector of values of `y` at the boundaries between bins, calculated using `pretty(y)` if not supplied.
`flatten` | A logical value indicating whether the return value also contains equilength vectors `x`, `y`, `z` and `n`, a flattened representation of `xmids`, `ymids`, `result` and `number`.

### Value

A list with the following elements: the breaks (`xbreaks` and `ybreaks`), the midpoints (`xmids` and `ymids`) between those breaks, and the count (`number`) of `f` values in the boxes defined between successive breaks.
