column_stats

column_stats can be used to obtain summary statistics of column(s) in a data set including count, mean, median, mode, Q1, Q3, variance, standard deviation, correlation, and covariance in table format. To use column_stats in a project:

library(EDAhelperR)
library(knitr)

Generate a dataframe of summary statistics, a correlation matrix, and a covariance matrix

data <- iris
columns <- c('Sepal.Length', 'Sepal.Width', 'Petal.Length')

column_stats(data, columns)
