Examples

# NOT RUN {
# Lat
g <- -33
m <- 38
s <- 30.123456

rad_lat <- radians(g, m, s)
print(rad_lat)

# To know the ellipsoids and the order open the Ellipsoids in the package and look for it number
Ellip <- Ellipsoids
#View(Ellip)

# We choose the number 5 which is GRS80
value <- E3(5, rad_lat, digits = 4)
print(value)
# }
