graph.pc {multisensi}

Principal Components graph for gsi objects

Description

A function that plots the Principal Components (PCs) and the sensitivity indices on each PC

Usage

graph.pc(x, nb.plot = 15, nb.comp = NULL, xmax = NULL,
         beside = TRUE, cor.plot=FALSE, xtick=TRUE, type="l", ...)

Arguments

x

gsi object.

nb.plot

number of input factors to be considered.

nb.comp

number of PCs.

xmax

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.

beside

if TRUE, the main and total sensitivity indices are represented by two bars; if FALSE, they are represented by the same bar.

cor.plot

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.
