The goal of blsR is to make it easy to request time series data from the BLS API and turn it into usable tabular data.
You can install the released version of blsR from CRAN with:
install.packages("blsR")And the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("groditi/blsR")blsR provides functions for retrieving and processing
data from the BLS API. The functions are divided into 4 categories:
query generators, query requests, result processors, and the
user-friendly simplified interface. It was designed with a three-step
workflow in mind:
bls_request()])If the only data needed is periods and values, then the functions
get_series_table, get_series_tables, and
get_n_series_table are all that a user will need. An API
key is not required to use this package but users will be restricted in
how many years of data can be retrieved per request, how many series can
be included per request, and how many requests can be made in a day. An
API Key can be obtained at: https://data.bls.gov/registrationEngine/ ## Example
This is a basic example which shows you how to retrieve one series as a tibble or retrieve two series as a joined tibble.
To request a single series as a tibble:
library(blsR)
uer <- get_series_table('LNS14000000', start_year = 2006, end_year = 2006)
# uer:
# # A tibble: 12 x 5
