Tidied datasets of confirmed exoplanets and their host stars, retrieved
from NASA’s Exoplanet Archive via the
REXoplanets package.
Column names have been simplified for classroom use, with units baked
into names where ambiguous. Intended as a companion dataset for
introductory statistics teaching in the spirit of the
moderndive textbook.
exoplanetdata ships ready-to-use, pre-tidied data frames
(planets and stars) that load instantly with data() and need no
network access — the column names, units, and types have been curated
for classroom use. It is not a client for the NASA archive.
If instead you want to query NASA’s Exoplanet Archive live and pull
down arbitrary tables and columns yourself, use the rOpenSci
exoplanets package (a
programmatic API client), or
REXoplanets, which
exoplanetdata itself uses to build its snapshots.
Once the package is on CRAN, install the released version with:
install.packages("exoplanetdata")You can install the development version from GitHub with:
# install.packages("pak")
pak::pak("moderndive/exoplanetdata")library(exoplanetdata)
# One row per confirmed exoplanet (host-star parameters merged in)
planets
# Reference-level stellar parameters (many rows per host star)
