ifuns

This package contains a Shiny app to interactively visualize univariate functions. To install the package

# install.packages("remotes")
remotes::install_github("tomicapretto/ifuns")

And fire the app with

ifuns::launch()

This is a simple demonstration of how you can use the app.

Notes

While the app works, this is a more like a proof of concept than a final version anyone could use to assist calculus teaching. Here I list some of the drawbacks that, hopefully, we could tackle in the future

1. Every function is computed along the same bounded grid of values. In the future I would like to implement something to obtain the domain of a function and assign each function a specific grid based on that domain.
2. The function is (re) computed along the same grid no matter if you're zooming in a specific part of the domain. I would like to compute each function only where it is being shown.
3. The plot height is fixed at 800px.
4. ... something I've missed?
