The goal of taxyvr is to provide an easy way to access the Vancouver housing assessment data. This is semi-tidied data obtained from the City of Vancouver’s Open Data Portal.
You can install the development version from GitHub with:
install.packages("devtools")
devtools::install_github("UBC-MDS/taxyvr")You may also access this information through our vignette. First use this command for installation:
install.packages("devtools")
devtools::install_github("UBC-MDS/taxyvr", build_vignettes = TRUE)And to read the vignette use:
library(taxyvr)
browseVignettes("taxyvr")This data was acquired courtesy of The city of Vancouver’s Open Data Portal.
