Because for example I've done this:
I made a simple table:
A B C
G1 1 34 231
G2 231 1 0.1
G3 12 0.02 23
and ran a correspondance analysis on it using the ca package:
> library(ca)
Loading required package: rgl
Warning messages:
1: In rgl.init(initValue) : RGL: unable to open X11 display
2: In fun(libname, pkgname) : error in rgl_init
> ca(table)
Principal inertias (eigenvalues):
1 2
Value 0.924588 0.007655
Percentage 99.18% 0.82%
Rows:
G1 G2 G3
Mass 0.498950 0.435362 0.065689
ChiDist 0.911602 1.079139 0.401921
Inertia 0.414636 0.506996 0.010611
Dim. 1 -0.947585 1.122145 -0.239642
Dim. 2 -0.326025 -0.194244 3.763758
Columns:
A B C
Mass 0.457683 0.065689 0.476628
ChiDist 1.046690 0.943948 0.883798
Inertia 0.501419 0.058531 0.372293
Dim. 1 1.088538 -0.923587 -0.917983
Dim. 2 -0.001466 -3.656541 0.505351
But i'm having trouble actually visualising a graph? Does anyone know, is it
because of the rgl issue/ is there an alternative way to turn this
correspondance analysis results into a graph? Basically i just want to
picture this correspondance analysis results graphically, using any method
:(
