vflayout_poplr: layout displaying the PoPLR analysis

Description

the function performs the PoPLR analysis (see poplr) with default values and presents the results in form of a A4 printout

Usage

vflayout_poplr( vf, grp = 3, nperm = 5000,
                      plotType = "vf", truncVal = 1,
                      type = "slr", typecomb = "fisher",
                      pwidth = 8.27, pheight = 11.69,
                      margin = 0.25, filename = NULL,
                      colorMapType = "pval", colorScale = NULL )

Arguments

vf

vf object with threshold sensitivities, td, or pd values

grp
