Hi Anjaly,
Here is a very simple way to plot something like this. There are many
ways to do this and of course easier ways to automate the placement of
the points and labels.
library(maps)
library(plotrix)
map("world",xlim=c(13.548932,53.407331),ylim=c(70.824046,78.764113))
box()
segments(20,76,25,77)
points(25,77,pch=19)
boxed.labels(20,76,"Kraken\nn=2\nlat=20 lon=76\nlength=10-20M")
segments(40,72,51,71)
points(51,71,pch=19)
boxed.labels(40,72,"Herring\nn=20000\nlat=51 lon=70\nlength=15-20cm")
