Create two dimensional datasets with decision boundaries set by linear splines. An HTML widget enables users to draw the splines on a web page and generate a JSON file that can be used to generate datasets.
The goal of sillysplines is to give you a simple HTMLWidget that can draw silly little linear splines in an HTML widget and then download the coordinates to create datasets from.
You can install the development version of sillysplines from GitHub with:
pak::pak("janithwanni/sillysplines")
You can install the CRAN version by running
install.packages("pak")
You start off by running sillysplines() from the package.
library(sillysplines)
sillysplines()
This should open up an HTML widget that shows a box containing an initial spline design. You can add points by clicking on intermediate areas, and you can drag points by clicking on the nodes.
Once done you can click Download boundary to get a JSON file containing the coordinates.
Then it’s a matter of using the create_data function to create a dataset of your size
create_data(coord_filepath="<yourfilenamehere.json>", n_samples = 1000)
