Con las bombas que tiran los fanfarrones, se hacen las gaditanas tirabuzones (Palma y corona, Carmen Linares)
This time I draw Franky again using an algorithm to solve the Travelling Salesman Problem as I did in my last post. On this occasion, instead of doing just one single line drawing, I overlap many of them (250 concretely), each of them sampling 400 points on the original image (in my previous post I sampled 8.000 points). Last difference is that I don’t convert the image to pure black and white with
threshold function: now I use the gray scale number of each pixel to weight the sample.
Once again, I use
ggplot2 package, and its magical
geom_path, to generate the image. The pencil effect is obtained giving a very high transparency to the lines. This is the result:
I love when someone else experiment with my experiments as Mara Averick did:

An image as a travelling salesman problem using #rstats. How did I do it? I didn't: I just cloned a #GitHub repo (https://t.co/u7GDUzsJRu) and put in my own picture. Really nice, follow his blog (https://t.co/rmOqmmsd6T) pic.twitter.com/zLYXokR6U7

P.S.: Although it may seems otherwise, I’m not obsessed with Frankenstein
