Dear UseRs,
I have a question regarding reading the coordinates within a country' map. I
drew map of ireland by using the following commands
library("maps")
library("mapproj")
map("world", "ireland")
map.axes()
You can clearly see the axis labelled. What is want to do is to draw lines (both
vertically and horizontally ) at an interval of 0.5. Which means if x-axis
starts from -10 then the first be on -10 and second on -9.5 and so on. Similar
has to be the case with y-axis.
Afterwards I only want to read the coordinates of the point falling with in the
boundary of ireland. I spent quite sometime while going through the previous
posts but couldnt find the answer.
Thankyou very much in advance,
Elisa
