[R] Boxplot using a shapefile

[Preethi Balaji]

Dear all,

I am trying to generate boxplots by giving a shapefile and an image as
input. The shapefile takes the pixel values from the image and shows
the distribution of pixels in the form of a boxplot.

Can somebody please tell me how I can execute this in R?

Many thanks!
