plot_2parOF

Description

This function plots the values of the objective function in a two dimensional box, where the boundaries of each parameter are used as axis limits

Usage

plot_2parOF(params, gofs, p1.name, p2.name, type="sp", MinMax=c("min","max"), 
            gof.name="GoF", main=paste(gof.name, "Surface"), GOFcuts, 
            colorRamp= colorRampPalette(c("darkred", "red", "orange", "yellow",
            "green", "darkgreen", "cyan")), points.cex=0.7, alpha=0.65, 
            axis.rot=c(0, 0), auto.key=TRUE, key.space= "right")

Arguments

params	matrix or data.frame with the parameter values
gofs	numeric with the values of goodness-of-fit values for each one of the parameters in params (in the same order!)
p1.name	character, name of the 1st parameter to be plotted
p2.name	character, name of the 2nd parameter to be plotted
type	character, type of plot. Valid values are: -) sp: spatial plot -) scatter3d: 3d scatterogram
MinMax	character, indicates whether the optimum value in gofs corresponds to the minimum or maximum of the objective function. Valid values are in: c('min', 'max'). By default, MinMax='min' which plot particles with lower goodness-of-fit values on top of those with larger values, in each one of the output figures
gof.name	character, name of the objective function to be plotted. It has to correspond to the name of one column of params
main	character with the title for the plot
GOFcuts	numeric, specifies at which values of the objective function given in gofs the colours of the plot have to change If GOFcuts is missing, the interval for colours change are defined by the (unique values of the) five quantiles of gofs, computed by fivenum
colorRamp	R function defining the colour ramp to be used for colouring the pseudo-3D dotty plots of Parameter Values, OR character representing those colours
points.cex	size of the points to be plotted
alpha	numeric between 0 and 1 representing the transparency level to apply to colorRamp, ‘0’ means fully transparent and ‘1’ means opaque
axis.rot	numeric vector of length 2 representing the angle (in degrees) by which the axis labels are to be rotated, left/bottom and right/top, respectively.
auto.key	logical, indicates whether the legend has to be drawn or not
key.space	character, position of the legend with respect to the plot
