I tried to use "paneliperf" in package SensoMinR, I imported my data "Choco" , my data looked like exactly same with data "sensochoc" in this package. the only difference is the value. I tried to run the code, res<-paneliperf(choco, formul = "~Product+Panelist+Session+ Product:Panelist+Product:Session+Panelist:Session", formul.j = "~Product", col.j = 1, firstvar = 5, synthesis = TRUE), the error message is "Error in `[.data.frame`(aux, 1, 5) : undefined columns selected" What is that , how to fix that? Thank a lot.
