setGpar {plgem} | R Documentation

## Set graphical parameters for PLGEM fitting evaluation plots

### Description

Function to set graphical parameters for PLGEM fitting evaluation plots produced by function `plgem.fit`.

### Usage

      setGpar(minLnM=NULL, maxLnM=NULL, minLnSD=NULL, maxLnSD=NULL,
        minRes=NULL, maxRes=NULL)

### Arguments

`minLnM` | minimum 'ln(mean)' value in upper left plot.
`maxLnM` | maximum 'ln(mean)' value in upper left plot.
`minLnSD` | minimum 'ln(sd)' value in upper left plot.
`maxLnSD` | maximum 'ln(sd)' value in upper left plot.
`minRes` | minimum 'residual' value in upper right plot.
`maxRes` | maximum 'residual' value in upper right plot.

### Details

A call to `setGpar()` is the recommended way to set graphical parameters in `plgem.fit`. If parameters are left unspecified, suitable defaults will be found by `plgem.fit`.

### Value

A `list` of six elements:

`minLnM` | minimum 'ln(mean)' value in upper left plot.
`maxLnM` | maximum 'ln(mean)' value in upper left plot.
`minLnSD` | minimum 'ln(sd)' value in upper left plot.
`maxLnSD` | maximum 'ln(sd)' value in upper left plot.
`minRes` | minimum 'residual' value in upper right plot.
`maxRes` | maximum 'residual' value in upper right plot.
