I have a dataset in R called Test with longitude latitude coordinates that now have the following format after having called str(Test):
$ lat : chr "513.035.763.793.677" $ lon : chr "33.941.883.804.984"
i would like to turn these into correct lon - lat coordinates. The following doens't work:
as.numeric(Test$lat) as.numeric(gsub(".", "", Test$lat)
 NA Warning message: NAs introduced by coercion
How can I transform them into numeric coordinates that are good to plot on a map? the correct coordinates should be lon: 3.394188 and lat: 51.30357
