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??
