Changing sign on absolute numbers 0 problems
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)
