Creating an animation using R

In this post, I will show you how to create an animation using R and ffmpeg. The idea to do so is pretty simple: Generate a number of snapshots Combine them in a video file using ffmpeg The best way to learn about the art of animation is by doing it ourselves, so our work Related Post

Smoothing Techniques using basis functions: Gaussian Basis

In my previous post, I introduced the concept of smoothing using Fourier basis functions and I applied them onto temperature data. It is important to note the that a similar kind of analysis can be replicated using B-splines (see this page). In this post, I extend the concept to an another type of basis functions:

Smoothing Techniques using basis functions: Fourier Basis

In this post we will introduce the Fourier basis functions in the context of Functional Data Analysis. The Fourier basis function is method to smooth out data varying over a continuum and exhibiting a cyclical trend. Smoothing techniques play an important role in Functional Data Analysis (FDA) as they provide insight in the functional behavior
