Weird and wonderful exploration of data using R

Webscraping with R - from messy & unstructured to blisfully tidy

I stopped caring about the estimates that occasionally raid the internet about how much time data scientists spend on data wrangling VS modelling. The answer is: probably a lot and likely more than originally planned (probably indicating here dependency on the state and richness of input data and the intended application for it, ekhem). Still, the right tools can go a long way in achieving the desired result in the time frame that can surprise even the most optimistic of us.

My R Take in Advent of Code - Day 5

There’s no time to lose, so here comes another Advent of Code puzzle solved using R. Day 5 challenge, here we come! What are we expected to do? The polymer is formed by smaller units which, when triggered, react with each other such that two adjacent units of the same type and opposite polarity are destroyed. Units’ types are represented by letters; units’ polarity is represented by capitalization.

My R Take on Advent of Code - Day 4

After some wonderful Christmas and New Year’s distractions, now it’s time to continue with my Advent of Code challenges in R (before the summer comes…). To avoid waffling, the 4th puzzle offers a record of guards’ shifts with various activities plus the time they started and time. We need to gather two things from this dataset: Which guard sleeps most (minutes) and What minute does that guard spend asleep the most?

End of 2018 Thoughts

Here we are, ending yet another year and starting something new. I wanted to take a minute to dwell on 2018, what happened in my R world this year and reflexions I take from that. public speaking This year started for me with a bang - as a result of my presentation about LIME at one of H2O meetups (of which YouTube video has now reached unthinkable 11K views!) I was invited to speak at various events - be it AI Congress, LSE’s Python Group or Data Science Festival.

My R Take on Advent of Code - Day 3

Ho, ho, ho, Happy Chris.. New Year? Between eating the sea of fish (as the Polish tradition requires), assembling doll houses and designing a new kitchen, I finally managed to publish the third post on My R take on Advent of Code. To keep things short and sweet, here’s the original challenge: Each Elf has made a claim about which area of fabric would be ideal for Santa’s suit.
