stretchPlot: Contrast adjustments for RasterLayer plots
In CENFA: Climate and Ecological Niche Factor Analysis

Description Usage Arguments Details Value Examples

A plotting function that provides methods for improving the contrast between values.

stretchPlot(x, type = "linear", n, ...)

## S4 method for signature 'RasterLayer'
stretchPlot(x, type = "linear", n, ...)

`x`	a RasterLayer
`type`	character. Possible values are "linear", "hist.equal", and "sd"
`n`	number of standard deviations to include if `type = "sd"`
`...`	Additional arguments for raster::plot

If type = "hist.equal", a histogram equalization procedure will be applied to the values of x. If type = "sd", the values of x will be scaled between values that fall between n standard deviations of the mean.

Returns a RasterLayer plot.

mod <- enfa(x = climdat.hist, s.dat = ABPR, field = "CODE")
sm <- sensitivity_map(mod)
stretchPlot(sm)
stretchPlot(sm, type = "hist.equal")
stretchPlot(sm, type = "sd", n = 2)
