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 divided by ':'
There are some values that are negative (eg -69:38:27)
I have R version 2.10.1 on a windows vista computer.
I could do it manually but I have like 20,000 entries and would really like a
little code to automate the conversion.
I have tried Microsoft Access and Excel, but because the data is not stored in
3 columns I cannot get it to work, I figured R was my best option but I cant
get
it to work. It should be really simple but I'm new to R so would
really appreciate help.
Thank you for reading my plea,
Any and all help is greatly appreciated,
sadz
