Getting started with the cansim package

About

The cansim package provides R bindings to Statistics Canada’s main socioeconomic time series database, previously known as (and frequently referred to in this package, and elsewhere, as) CANSIM. Data can be accessed by table number, vector or both table number and coordinate. The package accepts both old and new (NDM) CANSIM table catalogue numbers.

Installing cansim

The cansim package is available on CRAN and can be installed directly using the default package installation process:

install.packages("cansim")

Alternatively, the latest development version of the package can be downloaded from Github using the devtools or remotes packages.

# install.packages("remotes")
remotes::install_github("mountainmath/cansim")

library(cansim)

Usage

If you know the data table catalogue number you are interested in, use get_cansim to download the entire table.

By default, the data tables retrieved by the package comes in the original format provided by Statistics Canada and is enriched by several added columns and transformations.

Taking a look at an overview of the data within a table is a common first step. This is implemented in the package with the get_cansim_table_overview(table_number) function.

get_cansim_table_overview("14-10-0293")

When a table number is unknown, you can browse the available tables or search by survey name, keyword or title.

Individual series in Statistics Canada data tables can also be accessed by using individual numbered vectors. This is especially useful when building reports using specific indicators. For convenience, the cansim package allows users to specify named vectors, where the label field will be added to the returned data frame containing the specified name for each vector.

get_cansim_vector(c("Metro Van Apartment Construction Price Index"="v44176267",
                    "Metro Van CPI"="v41692930"),
                  start_time = "2015-05-01",
                  end_time="2015-08-01") |>
