How to merge plots (layers) in R Studio?


How can I merge two plots (layers)? On a first plot there are points with data, and on the second one there is a boundary of those points. Here is what i've got:

data <- read.csv('data.csv')
coordinates(data) <- ~x+y 
proj4string(data) <- '+init=epsg:2180' 
plot(data)
boundary <- readOGR(dsn='.', layer='boundary')
plot(boundary)

The thing is, that I want to merge boundary with data. I also want to change a colour of boundary. Thank you in advance.


Solution

  • What you want might be polygon

    #Example Data
    set.seed(42)
    mydata = cbind(rnorm(100),rnorm(100))
    boundary = mydata[chull(mydata),]
    
    #Plot points first
    plot(mydata,xlab="X-axis",ylab="Y-axis")
    #Then plot the boundary
    polygon(boundary,lty = 2)
