# calcLakeMetrics: Calculate all Lake Morphometry Metrics In lakemorpho: Lake Morphometry Metrics in R

## Description

This function is a wrapper function for all of the metrics. It calculates each metric for an input lakeMorphoClass. This returns a list of all metrics

## Usage

 `1` ```calcLakeMetrics(inLakeMorpho, bearing, pointDens, correctFactor = 1) ```

## Arguments

 `inLakeMorpho` an object of `lakeMorphoClass`. Output of the `lakeSurroundTopo` function would be appropriate as input `bearing` Numeric that indicates the bearing of the desired fetch. `pointDens` Number of points to place equidistant along shoreline for `lakeMaxLength` or density of lines to test for `lakeMaxWidth` and `lakeFetch`. `correctFactor` Value used to correct the predicted maximum lake depth. Defaults to 1. Corrections are simply accomplished by multiplying estimated max depth by correction factor. Correction factors can be determined empirically by regressing the predicted depth against a known maximum depth while forcing the intercept through zero. The slope of the line would then be used as the correction factor(Hollister et. al, 2011).

## Value

Returns a list with all lake metrics calculated for a given input lakemorpho object
