Overview
I just learned about the R trelliscope package. The question was whether a trelliscope widget could be embedded into a github page. The widget could be embedded into this blog by first creating a separate repository and then inserting an iframe on the blog post.
Step 1 - Create Repo
The address for the repository is here. The key is the script within the ./R folder.
Step 2 - Create Trelliscope Plot
This code was taken from the “Getting Started” page of the package’s documentation.
qplot(year, lifeExp, data = gapminder) + xlim(1948, 2011) + ylim(10, 95) + theme_bw() +
facet_trelliscope(~country + continent, nrow = 2, ncol = 7, width = 300)Step 3 - Save Widget to Docs
Create a ./docs folder. dir.create("./docs") should work. The place where I struggled was collecting and saving the widget. The files are kept in the temporary directory. The code was included in the issues thread of the package. (You can find it here.)
The strategy was to copy the files, libraries and directories generated from the package and place them in the docs folder. That was accomplished with the code below:
trell_files <- list.files("/tmp/gap", full.names = T)
file.copy(from = trell_files, to = "./docs", recursive = T)
Step 5 - Add iframe
Find the url address where GitHub published the page and insert it into the src attribute.
<iframe src="https://robwiederstein.github.io/trelliscope/#display=by_country_continent&nrow=2&ncol=7&arr=row&pg=1&labels=country&sort=country;asc&filter=&sidebar=&fv=" width=600, height=400 title="Trelliscope Plot"></iframe>Conclusion
The trelliscope package can provide insight on high-dimensional data. I’m really interested to see if it will work into a modeling workflow where the performance metrics are faceted with the different models. Something to experiment with in the future.
