https://github.com/afrimapr/afrilearnr/blob/main/inst/tutorials/test-tmap-view/test-tmap-view.Rmd
library(learnr)
knitr::opts_chunk$set(echo = FALSE)
library(tmap)
data("World")
tmap_mode("view")
tm_shape(World) +
tm_polygons("HPI")
Describe the problem in detail
The chunk above - the Hello World ! example from tmap, with tmap_mode(“view”) added, works when the tutorial is loaded, or on 'Start Over' or when run from console, but fails (with $ operator is invalid for atomic vectors) when ‘Run Code’ is pressed
