How to create multiple lines chart with unique line types in R?
Line types can be very different and they are helpful to differentiate among different variables. Mostly, it is used to plot trend data so that the trend for different variables can be visualized with a unique line. In R, we can use matplot function to create such type of multiple lines chart.
Example1
M1<−matrix(rpois(50,10),ncol=5) M1
Output
[,1] [,2] [,3] [,4] [,5] [1,] 6 14 13 4 9 [2,] 9 6 12 19 9 [3,] 11 3 14 17 8 [4,] 12 9 11 9 11 [5,] 8 15 17 8 5 [6,] 10 5 9 16 11 [7,] 15 7 9 11 4 [8,] 6 17 12 10 9 [9,] 14 14 8 5 15 [10,] 9 7 10 7 12
Example
matplot(M1,type="b",lty=1:5,col=1:5)
Output
Example2
M2<−matrix(rnorm(50,5,1.5),ncol=5) M2
Output
