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.
