When you do simulations, for instance in R, e.g. drawing samples from a distribution, it’s best to set a random seed via the function
set.seed in order to have reproducible results. The function has no default value. I think I mostly use
set.seed(1). Last week I received an R script from a colleague in which he used a weird number in
set.seed (maybe a phone number? or maybe he let his fingers type randomly?), which made me curious about the usual seed values. As in my blog post about initial commit messages I used the Github API via the
gh package to get a very rough answer (an answer seedling from the question seed?).

Recently a reader left a comment on this blog mentioning his cool blog post in which he mapped the spread of a migratory bird using Twitter. His data source was the Waxwings UK account which reports sightings of Bohemian waxwings in the UK. I decided to try reproducing and extending his work using the rOpenSci
spocc package that interfaces different sources of species occurrence data.

This week I was impressed by this tweet where Daniel Pett, Digital Humanities Lead at the British Museum, presented a collage of Twitter profile pics of all his colleagues. He made this piece of art using R (for collecting the usernames) and Python. I’m a bit of an R fanatic (or a Python dummy…) so I decided to write a code in R only to make a collage of profile pics of Twitter #rstats users.

One of my more or less guilty pleasures is reading The Guardian blind date each week. I think I started doing this when living in Cambridge, England for five months. I would buy i every weekday and The Guardian week-end every week-end. I wasn’t even dating at the time I discovered The Guardian blind dates but I’ve always liked their format.
I get so much into each date report that seeing both participants say they want to meet again makes me ridiculously happy. I like wondering how matches were made, but today I just want to look into the contents of post-date interviews.

It’s the second time I write a post about the blog aggregator R-bloggers, probably because I’m all about R blogs now that I have one. My husband says my posts are so meta. My first post was about R blogs names, in this one I shall focus on the last 1,000 tweets from R-bloggers.
