Hi, I am trying to do some calculations turning DMS data to decimal degrees using the formula (D+(M/60)+(S/3600)), some of the D's involve -ve numbers, the easiest way to do the calculation is to use absolute numbers then use the 'sign' function in R to change the answer back to the correct -ve or +ve, for example, if; D<--69 M<-8 S<-10 then decimal<-D+(M/60)+(S/3600)

Hi All, I have location data set up as degrees: minutes: seconds (for example, 122:45:45) I need to get this data into decimal degree form (122.7625). I know that I need to use the formula Decimal degrees = Degrees + (Minutes/60) + (Seconds/3600) Does anyone know how I can get R to do this? The original data is all in one column (called 'lat') and the degrees, mins and secs are
