multifile_zip_resources.RmdSome resources from the City of Toronto Open Data Portal are ZIP files containing multiple files. When a resource like this is retrieved using get_resource(), the result is a list with elements named after each file.
For example, the dataset on the Annual Summary of Reportable Communicable Diseases:
library(opendatatoronto)
library(dplyr)
summary_diseases <- search_packages("Annual Summary of Reportable Communicable Diseases") %>%
list_package_resources() %>%
filter(name == "summary-of-reportable-communicable-diseases-in-toronto-2007-2017") %>%
get_resource()
str(summary_diseases, max.level = 1)

#> $ DiseaseSexandAgegroups2017.csv : tibble [117 × 22] (S3: tbl_df/tbl/data.frame)
#> $ MeansbyDiseaseSex2007_2016.csv : tibble [120 × 13] (S3: tbl_df/tbl/data.frame)
#> $ RatesbyDisease2007_2017.csv : tibble [62 × 23] (S3: tbl_df/tbl/data.frame)
#> $ RatesbyDiseaseandSex2007_2017.csv : tibble [121 × 35] (S3: tbl_df/tbl/data.frame)
#> $ read me file for annual report data.xlsx: tibble [28 × 3] (S3: tbl_df/tbl/data.frame)To access a single file, you can pull out the element by name:
summary_diseases[["RatesbyDisease2007_2017.csv"]]
