We have scraped a dataset consisting of all chemical elements and around 80 properties and placed them in a more easily accessible format.
This R package includes two vignettes that demonstrate a few different approaches to construct the periodic table and how to plot a property. Our hope is that this package will make it easier for chemists and others interested in the chemical sciences to generate periodic tables of whatever trend they wish to visualise.
This package was based on some of my old projects (see Earlier work below). But I reworked most of the code in honour of the #IYPT2019 and released it as an R package.
If that piqued your curiosity, you might also like to read these blog posts that provide some more examples of working with the periodic data:
To install this package on your system, I suggest:
install.packages("remotes")
remotes::install_github("solarchemist/periodicdata")
To also build the vignette locally on your computer when installing this package, modify the last line to:
remotes::install_github("solarchemist/periodicdata", build_opts = c("--no-resave-data", "--no-manual"), build_vignettes = TRUE)
Check out the source code from this repo:
git clone https://github.com/solarchemist/periodicdata.git
I suggest the following package rebuild procedure:
devtools::check()
.
Should complete with no errors, warnings, or notes:── R CMD check results ──────────────────────────── periodicdata 0.2.2.9000 ────
Duration: 19.1s
0 errors ✔ | 0 warnings ✔ | 0 notes ✔
devtools::build_vignettes()
in the console. This recompiles the vignette
and populates the doc/
directory.doc
from .gitignore
(the build step keeps adding it).Contributions are welcome, no matter whether code, bug reports or suggestions!
To correct or extend this dataset please open an issue or a create a pull request. Other contributions or feedback are also welcome via this repo or contact me directly.
