Dear R Users, I am using a 'simple' script to draw maps with points. It runs fine with the following libraries: library(sp) library(maptools) library(maps) library(mapdata) library(RColorBrewer) library(MASS) library(rgeos) library(GISTools)
Until now, to prepare the input data, I have used manually some free net converter because the number of points to plot was not too high. Now I have much more points coordinates to convert from a GPS ° ' " (d m s) format to a decimal format which will be accepted by the R script to build maps. My initial data is of the form (tab delimited text file): nom lat long "D. antoinei" 6°04' S 50°12'W "D. antoinei" 3°45'S 49°40'W "D. antoinei" 3°1'49"N 53°6'24"W "D. barberoi" 13°03.3’S 71°32.7’W "D. barberoi" 10°59.3’S 75°25.5’W" and I need them in the format (tab delimited): nom lat long "D. antoinei" -11.944478527683975 -71.28298997950684 "D. antoinei" -12.833333 -69.333333 "D. antoinei" 3.333333 -60.283333 "D. barberoi" -10.366667 -67.683333 "D. barberoi" -15.314500 -55.970300 Is there some 'simple' R script to do such a conversion? I am using R v. 3.2.1. on a iMac OS 10.6.8. May be this topic had already been resolved but I was unable to find the result in the FAQs.
