Re: [R] conversion of d m s (lat) d m s (long) coordinates into decimal coordinates
Hi Rui,
I succeded to convert a coordinate from decimal to DMS formats but not the
inverse!!!
dd<- -52.55684
c<-dd2dms(dd, NS = FALSE)
c

The use of char2dms() function is not so easy because I cannot yet read() the
text file with the DMS coordinates (one col. with the points names, lat col.
and long. col.)!!

Hello,
Here is the link to the archived versions of package measurements [1].
But the edit to that answer has another solution, with sp::char2dms and you are
loading package sp.

Hope this helps,

There is no older package to do the same?

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):
nomlatlong
"D. antoinei"6°04' S50°12'W
"D. antoinei"3°45'S49°40'W
"D. antoinei"3°1'49"N53°6'24"W
"D. barberoi"13°03.3’S71°32.7’W
"D. barberoi"10°59.3’S75°25.5’W"
and I need them in the format (tab delimited):
nomlatlong
"D. antoinei"-11.944478527683975-71.28298997950684
"D. antoinei"-12.83-69.33
"D. antoinei"3.33-60.28
"D. barberoi"-10.37-67.68
"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.
Cheers
