parse coordinates into degrees, minutes and seconds

Usage

parse_parts_lon(str)

parse_parts_lat(str)

Arguments

str

(character) string including longitude or latitude

Value

data.frame with columns for:

  • deg (integer)

  • min (integer)

  • sec (numeric)

For negative values the sign is carried by the first non-zero part: -45.5 gives deg -45, min 30, but -0.5 gives deg 0, min -30. Minutes are always below 60 and seconds below 60, in absolute value.

NA/NaN given upon error

Examples

parse_parts_lon("140.4183318")
#>   deg min     sec
#> 1 140  25 5.99448
if (FALSE) { # \dontrun{
