How to cut a long text character in a plot in R-CodePudding

I have a long text that I want to plot to an image in R, the image size 300 x 200 pixel. The actual text will vary.

Example Image

Example Code

library(raster) 
myJPG <- stack("images/1.jpg")  # Image with 300 x 200 pixel size
plotRGB(myJPG)  

vt <- rep(1:100)
vt <- paste(vt, collapse = ' ')


text(x = 150, y = 70,
     labels = vt,
     adj = c(0.5,0.5),
     cex = 1,
     col = "white")

Example Result.

What I want to ask How to cut the text in labels automatically, and adjust it so all the text can be shown in the image?

CodePudding user response：

You can insert \n into your character vector vt to break a line. One way to do this automatically
