### I retrieve the data from the google document you can find here using Tal Galili code:
## I slightly modified Tal code to include popularity stats:
supplement.popularity <- supplements.data[ss,7]
supplements.df <- na.omit(data.frame(supplement.name, supplement.benefits, supplement.popularity, supplement.score)) ## remove rows containing NAs
colnames(supplements.df) <- c("name", "benefits", "popularity", "score")
## For sake of simplicity I select only the cardio metacondition
cardio <- (supplements.df[supplement.benefits=="cardio",])[, -2]
## For reproducibility I add the cardio data.frame so you can use it right away
cardio <- read.table(tc <-textConnection(
