How do I make a partial profile experimental design in R? I currently use the conjoint package or ALGdesign package, but they all use full profile designs.
For example, the below creates a full profile design where there is 1 level from each factor present library(conjoint) experiment<-expand.grid( price<-c("a1","a2","a3","a4","a5"), tag<-c("b1","b2","b3","b4","b5"), smell<-c("c1","c2","c3","c4","c5"), aroma<-c("f1","f2","f3","f4","f5")) design<-caFactorialDesign(data=experiment,type="fractional") print(design) print(cor(caEncodedDesign(design))) I would like a design where there isnât always a price or tag or smell or aroma shown for each card.
