Dear R help
I am having difficulty doing a biplot of the first two factors of a factor
analysis. I presume it is because the values in factor 2 for Milk and NUTS
are not displayed in the component loadings.
Loadings:
Factor1 Factor2
RedMeat 0.561 -0.112
WhiteMeat 0.593 -0.432
Eggs 0.839 -0.195
Milk 0.679
Fish 0.300 0.951
Cereals -0.902 -0.267
Starch 0.542 0.253
Nuts -0.760
Fr.Veg -0.145 0.325
It has no problem doing a normal plot using
plot(eurofood.fa$scores[,1], eurofood.fa$scores[,2])
But when I ask for a biplot I get
biplot(eurofood.fa$scores[,1], eurofood.fa$scores[,2])
Error in 1:n : NA/NaN argument
What can I do to overcome this??
