# rSL: To calculate the value of r, S and L. In GeodesiCL: Geometric Geodesy Functions

## Description

With this function it is possible to calculate the value of r, S and L.

## Usage

 `1` ```rSL(x, pto_lat, digits = 4) ```

## Arguments

 `x` Selection of Ellipsoid to work between 1 = 'PSAD-56', 2 = 'SAD-69', 3 = 'WGS-84', 4 ='GRS-80 (SIRGAS)'. `pto_lat` Point name and the latitude in radians as data.frame. `digits` Number of digits the seconds are `rounded` to. DEFAULT: 4

## Value

data.frame with the data in the following order: "Pt", "r", "S", "L".

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21``` ```# Point name Pto <- "St1" # Latitude g <- -33 m <- 38 s <- 30.123456 rad_lat <- radians(g, m, s) print(rad_lat) # Ellipsoidal height and Horizontal distance as data.frame pto_lat <- data.frame(Pto, 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 47 which is WGS84 value <- rSL(47, pto_lat, digits = 4) print(value) ```
