[R] Inputting Co-ordinates

[Don MacQueen]

Go to http://lib.stat.cmu.edu/R/CRAN/, click on the "Manual" link on 
the left, and get two of the documents:

An Introduction to R (approx. 100 pages, 650kB), based on the former 
"Notes on R", gives an introduction to the language and how to use R 
for doing statistical analysis and graphics.

R Data Import/Export (approx. 30 pages, 270kB) describes the import 
and export facilities available either in R itself or via packages 
which are available from CRAN.

Briefly, put your coordinates in a plain text file (two columns, x 
and y, similar to a spreadsheet), and use the scan() function to read 
them in from the file.
