How to use ggmap geocode in Exploratory
You can use ggmap’s geocode feature inside Exploratory to add geocode info to your data frame. And here is how.
Install ggmap
First install ggmap to Exploratory with R Package Installation Dialog
Add Custom Command
Then as a custom step, you can add a step like below that uses mutate_geocode.
ggmap::mutate_geocode(city, output = "latlon", source = "google")
Known Issue
It seems ggmap has an issue that sometime it raises error: is.character(location)
It says the issue is fixed in newer version which is not available on CRAN yet.
So in case you hit the issue, you might want to try to install newer version from github with RStudio like below.
.libPaths(“your_home_directory\.exploratory\R\3.4”) # for windows path style
library(devtools)
devtools::install_github(“dkahle/ggmap”, force=TRUE)
And please restart Exploratory and try it again.
