How does the conversion between decimal to binary or from binary to decimal behave? With another useless function, I have plotted the points (x = decimal number, y = converted binary number) on a scatter plot. Just to find out…

I firmly believe that animation and transition between different data states can give end-users much better insights and understanding of the data, than a single table with data points or correlation metrics. With help of ggplot, gganimate, you can quickly…
Generating violin boxplots from image. Yes, why not. 🙂 We create a raster image from a picture and calculating the ratio of the pixels on the scale of grayscale. The more the darker colour is represented in the pixels, the…
Yes. Finally, the Voronoi diagrams with the use of x11() function. This diagram is presentation of a plane that is partitioned every time, a user clicks on the canvas of x11. This plane is partitioned into smaller regions that are…
How about some colours in line graph? Or even more wacky? Nevertheless, let’s create a function that generates some sample “mocked” data and draws a line chart: And run all together with three parameters: n – number of data points…
Facets in ggplot2 are great for showing multiple plots on a single canvas. Assuming this usually covers many scenarios, there might be a case that you would want to save all the combinations of x and y variables in a…
Using pipe %>% or chaining commands is very intuitive for creating following set of commands for data preparation. Visualization library ggplot in this manner uses sign “+” (plus) to do all the chaining. What if we would have to replace…
Taking a jpg image and converting it to raster, getting pixelized data manipulation of the image and plot a scatter image. Sound like another useless R function, that can produce a scatter plot in a shape of a logo with…
I have decided to tackle this year’s Advent Of Code using R (more or less). I know there are more preferred languages, such as Python, C#, Java, JavaScript, Go, Kotlin, C++, Elixir, but it was worth trying. Into the 8th…
Hangman is a classic word game in which you need to need to guess as many possible letters in word, so you can guess the word, before running out of tries (lives). Upon running out of tries, you are hanged!…
