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,

Hi Rui,
Thanks for the information.
Unfortunately, my versions of MacOS and of R are too old:
> install.packages("measurements")
Warning message:
package ‘measurements’ is not available (for R version 3.2.1)
> library(measurements)
Warning message:
le package ‘measurements’ a été compilé avec la version R 3.2.5
There is no older package to do the same?
Cheers
Nicolas

Hello,
See if this StackOverflow.com <http://StackOverflow.com> post [1]
solves your problem.
Also, examples should be minimal, you don't need all those packages to
solve this problem.

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"-12.833333-69.333333
"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.
Cheers
Nicolas Degallier
