[RobAStBase] comparePlot, infoPlot, and the plot-Method for ICs gain an argument x.vec; if given it is the x-grid on which to evaluate the ICs; by default this argument is NULL; then (as before) the grid is selected automatically according to the distribution of the IC. This can be useful for usage with a rescaling of the x-Axis to avoid that the evaluation points be selected too unevenly (i.e. on an equally spaced grid in the original scale, but then, after rescaling non-equally... The grid has to be specified in original scale; i.e.; when used with rescaling, should be chosen non-equally spaced...
