I urge you to install.packages("ExPanDaR") and then try the following:
library(ExPanDaR)
wb <- read.csv("https://joachim-gassen.github.io/data/wb_condensed.csv")
ExPanD(wb, cs_id = "country", ts_id = "year")
from Interactive panel EDA with 3 lines of code, which doesn’t show the output to its best advantage, for which see online demo
