Driving Directions from R There is no reason that maps with driving directions cannot be produced in R. Given the directions api from Google, it should be doable. As it happens, I was surprised how easy it was. Let me try to map a simple A to B location. First, to the locations; I will specify two. It is possible to geolocate addresses for this also, I happened to have the GPS coordinates in hand.
tidyTuesday on the Carbon Footprint of Feeding the Planet The tidyTuesday for this week relies on data scraped from the Food and Agricultural Organization of the United Nations. The blog post for obtaining the data can be found on r-tastic. The scraping exercise is nice and easy to follow and explored a case of cleaning up a very messy data structure. I took this exercise as practice for using pivot_wider and pivot_longer.

Updating Hugo: It’s Changed Alot… Many key features of hugo have been in a state of flux since I began this blogdown a few years ago. It was time to update hugo and the academic theme that I have built around and customized. A number of things broke. The config.toml and the like In my original website, there was only one configuation file. Now it has split into four parts; for blogdown, config.
First, I wanted to acquire the distribution of letters and then play with that. I embedded the result here. The second step is to import the tidyTuesday data. library(tidyverse) Letter.Freq <- data.frame(stringsAsFactors=FALSE, Letter = c("E", "T", "A", "O", "I", "N", "S", "R", "H", "D", "L", "U", "C", "M", "F", "Y", "W", "G", "P", "B", "V", "K", "X", "Q", "J", "Z"), Frequency = c(12.02, 9.1, 8.12, 7.68, 7.31, 6.95, 6.28, 6.
Mapping Points in R My goal is a streamlined and self-contained freeware map maker with points denoting addresses. It is a three step process that involves: Get a map. Geocode the addresses into latitude and longitude. Combine the the two with a first map layer and a second layer on top that contains the points. From there, it is pretty easy to get fancy using ggplotly to put relevant text hovers into place.
