How to create a racing bar chart

Once the data is fed, it generates link to the output (an html object) which it can be embedded within any Rmd report., gitbook or even a shiny app

The tool is free and easy to use. Actually, the template (racing bar chart) is already available so it just needs data in specific format. The session can be conducted within 15-20 mins.

cjyetman commented 4 years ago

I have used packrat, which is the precursor of renv (as far as I understand). I think it can be very useful, but also in my experience it's a bit confusing to use, and if some users do it wrong and then commit, it snowballs into a lot of problems that are difficult to resolve. Because of that, I avoided this topic for ds-incubator because I was afraid it's too large of a topic to cover in this format, but maybe I should suck it up and see if I can squeeze the essentials into a short presentation. I'll look into that.

The conflicted package:

Inspired by a peer-debugging session with @looreen a while ago; by this discussion with @cjyetman and @jdhoffa about when to use ::; and by a slack conversation with @tposey28.

maurolepore commented 4 years ago

The pins package.

Inspired by efforts by @tposey28 to move away from local Dropbox folders (see article on using pins with azure boards), and by this conversation with @cjyetman and @jdhoffa about showing examples with data that comes from packages listed under DESCRIPTION > Suggests -- is pins an elegant solution?)

Assertions: Are we using enough of them? When to build your own versus reusing existing packages such as: assertr, assertthat, or other? See this issue.

-- Thanks @jdhoffa for motivating this post (I suspect @vintented would be interested)

maurolepore commented 4 years ago

What is the difference between sourcing a file, cloning a package and running load_all(), and installing a package with install.packages() or install_github().
