brickset: An R Package to Interface with the Brickset API for Getting Data About LEGO sets

Author: Jason Bryer, Ph.D. jason@bryer.org
Website: https://jbryer.github.io/brickset/

This package provides functions to access data about LEGO sets from the Brickset website. The package also contains a data.frame with all LEGO sets (n = 18,455) from 1970 through 2022. This data set was created using the getSets function and it is recommended that you use this data frame to reduce the number of API calls. See the build.R script for how the data frame was created. Information about the variables is included below.

Installation

You can download from CRAN using:

install.packages('brickset')

Or the latest development version using the remotes package:

remotes::install_github('jbryer/brickset')

Brickset API

To use the Brickset API, you must first create a Brickset account and request an API key. The full Brickset API documentation is available here: https://brickset.com/article/52664/api-version-3-documentation

Most of the functions require a Brickset username, password, and API key. You can pass these as parameters, or you can set these options:

options(brickset_key = 'YOUR_API_KEY',
        brickset_username = 'YOUR_USERNAME',
        brickset_password = 'YOUR_PASSWORD')

The checkKey function will verify that your API key is valid:

brickset::checkKey()
#> [1] TRUE

You can check your API usage with the getKeyUsageStats function.

brickset::getKeyUsageStats()
#>              dateStamp count
#> 1 2023-03-30T00:00:00Z     3
#> 2 2023-03-24T00:00:00Z     2
#> 3 2023-03-23T00:00:00Z     2

#> 5 2023-03-21T00:00:00Z     2

The getSets function returns all LEGO sets from the given year.

The getReviews function will return all reviews for a given set.

reviews29830 <- brickset::getReviews(29830)
names(reviews29830)
#>  [1] "author"             "datePosted"         "title"

legosets Dataset

The legosets data frame contains all LEGO sets (n = 18,455) from 1970 through 2022.

data("legosets", package = "brickset")
ggplot(legosets, aes(x = year)) + geom_bar() +
    ggtitle('Number of LEGO sets by year') +
    xlab('Year') + ylab('Number of LEGO Sets')

ggplot(legosets, aes(x = pieces, y = US_retailPrice)) + 
    geom_point() +
    ggtitle('Cost of LEGO sets by number of pieces') +
    xlab('Number of LEGO pieces') + ylab('US Retail Price (dollars)')
