Introduction In this era of COVID19 digital explosions, people are noticing how much of our work CAN be done digitally, as well as the benefits of adopting an online way of life.

Feature leaking - When you have a dataset that gathers data over a period of time, the feature importance might change, making the model a bit weaker.

Creating an R package can be a daunting task, but there are several tools to facilitate this process immensely.

Anyone that has ever looked at local crime statistics has probably had the same initial reaction: “wow this neighbourhood has become so violent, I can’t ever leave the house again!”

I am working on a super-secret project for which I am harvesting a highly confidential source of data: twitter ≡ƒÖé The idea is to gather a small amount of twitter data, but for a long time… maybe a year.

Shiny is awesome, but can be a bit daunting and easy to make mistakes in.

I have been reading more and more about how people can’t interpret charts… which kinda never occurred to me, if I’m gonna be very honest.

This is a lightening quick post just providing the script to draw a heart-shaped wordcloud, using the awesome This is a lightening quick post just providing the script to draw a heart-shaped wordcloud, using the awesome package.

There are many ways to automate your scripts running, for example using RScript, or in-R itself (and now even as an add-in for RStudio) (check all here).

I am not sure how, but I found Data Science Africa, whose mission it is to promote data science in Africa.

Update!!

So Key Performance Indicators (KPIs) are all the rage in the dashboarding community… well So Key Performance Indicators (KPIs) are all the rage in the dashboarding community… well really.

I am proud to announce that with a little bit of encouraging from friends, I submitted my blog for inclusion in the prestigious r-bloggers and it was accepted!

This post explores the inter-relationships of StackOverflow Tags for R-related questions.

So people look up what to buy for mom most, wife second, husband third, and finally poor dad last… Notice that the peaks are always around christmas, then at valentines day, then mothers day and finally fathers day.

“… but I paid 10 yesterday!”

YAAAAAAAAY!!!!

In the midst of our random data exploration, Laure and I started playing around with Hadley’s movies dataset and noticed that there were a lot of old cartoon animations… I mean REALLY old.

The last task I performed for AQUASTAT was to try to find the best way to estimate the anthropogenic evaporation from dams.

I co-wrote this analysis with Laure Belotti to identify the difference between movie scripts for chick flicks and action movies using sentiment analysis, among other stuff.

When I told my friends that I wanted to give my girlfriend an infographic of us (centered around a sentimental analysis of our texts) as a gift for our first anniversary, most of them told me that was a terrible idea.

Following the footsteps of this cool post I saw by JohnNelsonIDV, I wanted to try to and make a map using Excel.

Visualizations made for FAO AQUASTAT: After individual Irrigated Crop Calendars for all countries were combined, it allowed for some interesting analysis of global irrigation.

A visualization prepared for FAO AQUASTAT: In an interest to simplify the information about renewable water resources in all countries in the world, we prepared simplified visualizations of water flows through a country.

So I had a happy little blog… no one really paid attention, but I didn’t much care because I was happy.

A better way to pick colours with ggplot2 First, get the excellent package by Marco D Visser: library(devtools) install_github("MarcoDVisser/choosecolor") call it library(choosecolor) This lets us interactively pick colors ourselves.

Most of the things posted on this page will make reference to Visual Basic for Applications (VBA).

So I guess everybody let’s you upload a “cover picture”…. something that should be beautiful, emblematic of you, deep, thoughtful etc.
