Az idei useR! konferencia szervezői érdekes pályázatot írtak ki (a 4 évvel ezelőtti hagyományok mentén): tervezzük meg a konferencia “reproducible” pólóját! Ez annyit tesz, hogy a póló elején szereplő design-elem (plot) reprodukálható kell, hogy legyen a póló hátuljára nyomtatott R kód segítségével.
A pályázatokat ennek megfelelően GitHub-on várják, ahova eddig 10 pályamű érkezett:
A fentebb bemutatott megoldások részletes leírása és forráskódja elérhető az http://daroczig.github.io/t-shirt oldalon. Egy hazai pályázat kódja:

library(pixmap) ## get R logo into a matrix R <- read.pnm( system.file('pictures/logo.ppm', package = 'pixmap')[1]) ## drop colors R <- addChannels(R)@grey ## create a matrix full of "useR! 2014" T <- matrix( strsplit('useR!2014', '')[[1]], nrow = nrow(R), ncol = ncol(R), byrow = TRUE) ## remove cells not in the R logo T[which(R > 0.85)] <- ' ' ## save to disk write.table(x = T, # never abbreviate TRUE to T :) file = 'tshirtImage.txt', row.names = FALSE, sep = '', col.names = FALSE, quote = FALSE) |
A konferencia résztvevői online kérdőíven szavazhatnak, hogy melyik pólóterv legyen az idei rendezvény hivatalos arculata.
Friss hír, hogy a versenyt sikerült megnyerni: https://twitter.com/DataScienceLA/status/478282880112541696
Remélem, hogy néhány extra pólót el tudunk hozni a magyar R közösség tagjai számára 🙂
