###Creating Data#####
n <- 30
TestData <- data.frame(Group = sample(paste0("Group", 1:5), n, replace = TRUE),
                       Data1 = rnorm(n),
                       Data2 = rnorm(n),
                       Data3 = rnorm(n) + rnorm(n) + rnorm(n))

#Set colors:"scales" package
x <- seq(0, 1, length = 5)
ColData <- seq_gradient_pal(c("#e1e6ea", "#505457", "#4b61ba", "#a87963",
                                       "#d9bb9c", "#756c6d", "#807765", "#ad8a80"))(x)
