putting circles/buffers arround points on a 2D graph/plot
...able called 'Buffer', there are 5 buffer sizes (250, 500, 1000, 3000, 10000).
to create the plot I simply used
>plot(percent.forest,metric)
to add in the data about buffer size, I have extracted the percent forest and metric data by:
>buff250<-subset(data1,data1$Buffer==250)
>buff500<-subset(data1,data1$Buffer==500)
>buff1000<-subset(data1,data1$Buffer==1000)
>buff3000<-subset(data1,data1$Buffer==3000)
>buff10000<-subset(data1,data1$Buffer==10000)
i then used the 'points' function to plot the percent forest, metric data points in different colours...
