I am using the function GPA in the R package "FactoMineR" on sensory data, a method called Free Choice Profiling. The GPA function performs a general procrustes analysis on the data, afterwards I am able to plot the results with the function plotGPA from the same package.
My question: Is it possible to label the points of the scatterplot made using the plotGPA function? It does not seem to be an option in this function as standard.
XLstat in excel has this option, but I would like to do it in R as well.
my data: https://ufile.io/l6i19
my code:
library(FactoMineR)
blomkaal <- as.data.frame(read.csv(file="blomkaal.csv",sep=";",row.names=1,header = TRUE))
c.blomkaal <- apply(blomkaal, 2, gsub, patt=",", replace=".")
c.blomkaal <- as.data.frame(c.blomkaal,stringsAsFactors=FALSE)
for (i in 1:60){
c.blomkaal[,i] <- as.numeric(c.blomkaal[,i])
}
blomkaal.gpa <- GPA(c.blomkaal, group=c(6,6,6,6,6,6,6,6,6,6),name.group = c("Chris","Torben","Mie","Lone N","Aase","Annemette","Lone" ,"Iben","Lena","Ines"))
plot.GPA(blomkaal.gpa)
