Example：

Library

library(fmsb)

Create data: note in High school for Jonathan:

data <- as.data.frame(matrix( sample( 2:20 , 10 , replace=T) , ncol=10))
colnames(data) <- c(” 数学” , “english” , “biology” , “music” , “R-coding”, “data-viz” , “french” , “physic”, “statistic”, “sport” )

To use the fmsb package, I have to add 2 lines to the dataframe: the max and min of each topic to show on the plot!

data <- rbind(rep(20,10) , rep(0,10) , data)

Check your data, it has to look like this!

head(data)
