Dear R-helpers,
I have dist class objects for 10 individuals rating the
dissimilarities (on a 100-point scale) of the same 10 faces (analogous
to the bread data). I would like to get an individual differences
scaling jointly for the individual judges and the faces, and plot them
on the same axes.
This is the example:
library(smacof)
data(breakfast)
res.rect<-smacofRect(breakfast, itmax = 1000)
plot(res.rect, joint = TRUE, xlim = c(-10, 10))
However, smacofIndDiff() doesn't produce the desired form of output.
This is the bread example, which has data in roughly the same form as
mine:
data(bread)
res.uc <- smacofIndDiff(bread, itmax = 1000)
Thanks,
