Analysis in R: Presented in R MarkDown! A lot of color palette “ggsci” package

This is an introduction to a package that contains a color palette that can also be used with ggplot2. The color palette can be verified by running the rmd file in the command introduction.

The package version is 2.9. Tested with R version 4.2.2.

Install Package

Run the following command.

#Install Package
install.packages("ggsci")

Example

See the command and package help for details.You can download the file below and run it in RStudio to get the same results as the introduction of the same command. The file extension is Rmd.

###Creating Data#####
n <- 100
TestData <- data.frame("Group" = sample(paste0("Group", 1:5), n, replace = TRUE),
                          "Data1" = sample(1:10, n, replace = TRUE),
                          "Data2" = sample(LETTERS[1:24], n, replace = TRUE))
