elev.to.list {CTFS} | R Documentation

## Converts a Dataframe of Elevation Values to a Matrix

### Description

Converts the dataframe of x, y coordinates and elevation to a list with two objects: the original data frame and the same data in matrix format. The matrix format is useful for making maps and calculating mean topographic values for quadrates.

### Usage

    elev.to.list(elevfile, gridsize = 5)

### Arguments

`elevfile` | data frame of x, y coordinates and elevation, `bcielev.info`
`gridsize` | scale of elevation values (m)

### Details

This function creates two versions of the same information, as the original data frame and as a list. The point of this is that other functions rely upon one or the other object structure.

### Value

A list composed of

`col` | data frame of x, y coordinates and elevation
`x` | x coordinate, East-West
`y` | y coordinate, North-South
`elevation` | elevation, in meters
`mat` | matrix in the orientation of the plot
