In arnima-github/gmt: Interface Between GMT Map-Making Software and R

Convert Numeric to Degrees

Description

Convert decimal number to deg:min:sec string.

Usage

num2deg(x, lat=NA, dec=FALSE, digits=0, zero=FALSE)

Arguments

x	number or vector of numbers.
lat	whether x is latitude.
dec	whether to return decimal degrees instead of deg:min:sec.
digits	precision used when rounding decimal degrees or seconds.
zero	whether trailing :00 zeros should be retained.

Details

Element-specific format is supported, using vectors for lat, digits, and precision.

The resulting string ends with N or S when lat is TRUE, E or W when lat is FALSE, or a number when lat is NA.

Value

deg:min:sec string representation of the number(s).

Note

The string format is adopted from Appendix B.1.1 in the GMT manual.

        dec=c(FALSE, TRUE,  FALSE,   FALSE),
        digits=c(1,  1,     0,       0))
