gwpca.glyph.plotR Documentation

Multivariate glyph plots of GWPCA loadings

Description

This function provides a multivariate glyph plot of GWPCA loadings at each output location.

Usage

gwpca.glyph.plot(ld,loc, r1=50, add=FALSE,alpha=1,sep.contrasts=FALSE)

Arguments

ld

GWPCA loadings returned by gwpca

loc

a two-column numeric array for providing evaluation locations of GWPCA calibration

r1

argument for the size of the glyphs, default is 50; glyphs get larger as r1 is reduced

add

if TRUE, add the plot to the existing window.

alpha

the level of transparency of glyph from function rgb() and ranges from 0 to max (fully transparent to opaque)

sep.contrasts

allows different types of glyphs and relates to whether absolute loadings are used (TRUE) or not

Note

The function “glyph.plot” (in the early versions of GWmodel) has been renamed as “gwpca.glyph.plot”, while the old name is still kept valid.
