Plots Legend

Description

Plots the legend for resistivity values.

Usage

plotLegend(.Object, legend.lab = expression(paste("Resistivity [", Omega,
  " m]")), minData = 0, maxData = 999999, breaks = NULL,
  legend.line = 2.2, nlevel = 18, lab.breaks = c(), horizontal = T,
  col = colors, trafo = log, backtrafo = exp, ...)

## S4 method for signature 'ProfileSet'
plotLegend(.Object, legend.lab,
  minData = .Object@minData, maxData = .Object@maxData)

## S4 method for signature 'Profile'
plotLegend(.Object, legend.lab,
  minData = .Object@processedData@minData,
  maxData = .Object@processedData@maxData)

Arguments

.Object	either a single Profile or a ProfileSet.
legend.lab	label of legend (default: expression(paste("Resistivity [", Omega, "]"))).
minData	minimum value.
maxData	maximum value.
breaks	Break points in sorted order to indicate the intervals for assigning the colors. Note that if there are nlevel colors there should be (nlevel+1) breakpoints. If breaks is not specified (nlevel+1) equally spaced breaks are created where the first and last bin have their midpoints at the minimum and maximum values in z or at zlim.
legend.line	distance in units of character height (as in mtext) of the legend label from the color bar. Make this larger if the label collides with the color axis labels.
nlevel	number of color levels.
lab.breaks	number of breaks.
horizontal	If false legend will be a vertical strip on the right side. If true (default) the legend strip will be along the bottom.
col	vector of colors.
trafo	transformation to be done on data (default: log). For linear scale: function(x) x.
backtrafo	back transformation to plot correct labels (default: exp). For linear scale: function(x) x.
...	image.plot arguments.

           minData=100, maxData=50000)
