Create Multiple Plots with For Loop in R

Loop with R

Starting this week, I will incorporate more content that has to do with R into this SubStack page.

According to R-Project.org, R is a language and environment for statistical computing and graphics.

Today, I would like to show you how to use R to create multiple plots at once.

my_data <- data.frame(x=rnorm(100), y=rnorm(100), z=rnorm(100))

for (col_name in names(my_data)) {

  hist(my_data[[col_name]], main=col_name)

}

In the code chunk above, I have defined a data frame that’s made up of three columns, x, y, and z, each consisting of 100 sample values from a normal distribution. The for loop plots the distribution of numerical values contained in each of the columns.
