The following are examples of plots in the “ggplot2” package with “one variable: continuous variable” and “two variables: combination of continuous and discrete variables”. The commands for each data example are also presented, so please refer to the data format for the plots.
In order to use the “ggplot2” package, the “tidyverse” package is used.
Package version is 1.3.1. Checked with R version 4.2.2.
Install Package
Run the following command.
#Install Package
install.packages("tidyverse")
Example
・Loading the “tidyverse” package and creating example data
#Loading the library
library("tidyverse")
###Creating Data#####
set.seed(1234)
n <- 300
TestData <- tibble(Group = sample(paste0("Group", 1:4), n,
replace = TRUE),
X_num_Data = sample(c(1:50), n, replace = TRUE),
Y_num_Data = sample(c(51:100), n, replace = TRUE),
Chr_Data = sample(c("か", "ら", "だ", "に",
"い", "い", "も", "の"),
n, replace = TRUE),
Fct_Data = factor(sample(c("か", "ら", "だ", "に",
"い", "い", "も", "の"),
n, replace = TRUE)))
