Summarise data with skimr package in R

A nice way to summarise all the variables in a dataset.

install.packages("skimr")
library(skimr)

The data we’ll look at is from the Correlates of War . It provides dyadic records of militarized interstate disputes (MIDs) over the period of 1816-2010.

skim(mid)

n_missing : tells which variables have missing values

complete_rate : the percentage of the variables which are missing

Column 4 – 7 gives the mean, standard deviation, min, 25th percentile, median, 75th percentile and max values.

The last column is a histogram of each variables, so you can easily scan and see if variables are normally distributed, skewed or binary.
