gwpca.glyph.plot: Multivariate glyph plots of GWPCA loadings

In GWmodel: Geographically-Weighted Models

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.
