A function that plots the Principal Components (PCs) and the sensitivity indices on each PC
graph.pc(x, nb.plot = 15, nb.comp = NULL, xmax = NULL,
beside = TRUE, cor.plot=FALSE, xtick=TRUE, type="l", ...)gsi object.
number of input factors to be considered.
number of PCs.
a user-defined maximal \(x\) value (\(x\leq 1\)) in all the bar graphs that show sensitivity indices; or NULL if the user wants to keep default values.
if TRUE, the main and total sensitivity indices are represented by two bars; if FALSE, they are represented by the same bar.
if TRUE a correlation graph is made to represent the PCs ; if FALSE (default) a functionnal boxplot of the PCs is plotted.
if TRUE, put column names of outputs (Y) as ticks for the x axis.
what type of plot should be drawn for correlation graph ("l" for lines).
graphical parameters.
