# Distance Along Rhumb Line in R (Example)

In this R article youâ€™ll learn how to **calculate the distance between two geospatial points along a loxodrome**.

Letâ€™s dive right into the exemplifying R code!

## Creation of Example Data

At the start, weâ€™ll have to construct some example data:

my_points <- matrix(c(81.25798, 73.81277, # Create longitude/latitude matrix 14.91254, 18.18145), nrow = 2) colnames(my_points) <- c("longitude", "latitude") rownames(my_points) <- c("pt_1", "pt_2") my_points # Print longitude/latitude matrix

The previous table shows that the example data contains two geographical points stored in two columns.

## Example: Calculate Distance Along a Rhumb Line Using distRhumb() Function of geosphere Package

In this example, Iâ€™ll explain how to compute the distance between two geospatial points (i.e. longitude and latitude) along a rhumb line using the distRhumb function.

The distRhumb function is provided by the geosphere package and hence we first have to install and load the geosphere package:

install.packages("geosphere") # Install & load geosphere package library("geosphere")

As next step, we can apply the distRhumb function:

my_dist <- distRhumb(my_points) # Calculate Rhumb distance my_dist # Print Rhumb distance # [1] 873730.6

As you can see based on the previous output of the RStudio console, the distance between our two geospatial points is 873730.6 according to the calculation along a rhumb line.
