## Example 1 data(chocolates) resdecat<-decat(sensochoc, formul = "~Product", firstvar = 5, graph = FALSE) coltable(magicsort(resdecat$tabT), level.lower = -1.96, level.upper = 1.96, main.title = "Products' description") ## Example 2 data(chocolates) resperf<-paneliperf(sensochoc, formul = "~Product+Panelist+Product:Panelist", formul.j = "~Product", col.j = 1, firstvar = 5, lastvar = 12, synthesis = FALSE, graph = FALSE) res.sort=magicsort(resperf$prob.ind, method = "median") coltable(res.sort, main.title = "P-values of the F-test by panelist")
