A Few Joyful Moments of A Software Developer

A Few Joyful Moments of A Software Developer

Maëlle Salmon announced her “new session” (a cute newborn) on Twitter, and I was delighted and honored to see the knitr hex logo on her blanket. Welcome to the woRld, little Émile! That reminded me of a few other joyful moments. Occasionally, I receive thank-you notes and gifts from users, such as this card in a package: and this picture in an email: The instructor in the above picture ran…

Schedule R Code to Be Executed Periodically

Schedule R Code to Be Executed Periodically

A couple of months ago, while I was trying to implement an alternative approach for LiveReload in blogdown (Section D.2) using Hugo’s built-in server, I played with Joe’s later package for a little while, and my colleague Gabor gave me an interesting, useful, and elegant tip. I thought it might be useful to other people, too, so I’m writing it down here. Motivation The original problem I wanted to solve…

The 501st Reminder About Reproducible Examples

The 501st Reminder About Reproducible Examples

First thing first. This post is not meant to complain. It is just to document one “miserable” aspect of a software developer’s (daily) life. I wrote about the “reproducible example paradox” last month, and said I probably had reminded users 500 times of providing a reproducible example. Perhaps it was the 501st time this morning in rstudio/markdown#86. I’m okay with constantly reminding users, and I totally have the patience for…

splitting a field by annealing

A recent riddle [from The Riddle] that I pondered about during a [long!] drive to Luxembourg last weekend was about splitting a square field into three lots of identical surface for a minimal length of separating wire… While this led me to conclude that the best solution was a T like separation, I ran a […]

Astrostatistics school

What a wonderful week at the Astrostat [Indian] summer school in Autrans! The setting was superb, on the high Vercors plateau overlooking both Grenoble [north] and Valence [west], with the colours of the Fall at their brightest on the foliage of the forests rising on both sides of the valley and a perfect green on […]

"I thought it was obvious to you," he said. "No."

"I thought it was obvious to you," he said. "No."

When I talked about the minimal reproducible paradox in a previous post, I meant an example that other people can run or compile. That is one way to tell other people how to reproduce an issue, and it is also the easier way, because everything is contained in one example, and hopefully the issue can be reproduced in a single step. The other way is to clearly state the steps…

Are These Still The R Manuals I Knew?!

Are These Still The R Manuals I Knew?!

Colin Fay converted all official R manuals to bookdown books, which sounds amazing to me. I suddenly feel these are not the manuals I used to know. I should not judge manuals by appearance, but these manuals with the new styles (borrowed from Gitbook by bookdown) actually make me want to read them again. “I had no idea these manuals existed,” said tj mahr.

The blogdown Logo

The blogdown Logo

Last month when I finished the first draft of the blogdown book, I was thinking that I need a logo for this package, so that we can get some hexbin stickers of blogdown at rstudio::conf 2018. I’m pretty bad at art design, so I asked on Twitter for help. I got a lot of suggestions and drafts, which made it very difficult for me to decide, but eventually I chose…

Thanks, Karl, for Cross-referencing on Github!

Thanks, Karl, for Cross-referencing on Github!

Today is my second day of triaging Github issues of the rmarkdown repo. I just came across rstudio/rmarkdown#980, an issue that is almost 8 months old. I didn’t immediately start working on it, but took a look at the cross-references first. Then I saw Karl Broman cross-referenced this issue from ramnathv/htmlwidgets#265, so I clicked the link and went over there. Problem solved. I didn’t need to do anything, and happily…

[summer Astrostat school] room with a view [jatp]

I just arrived in Autrans, on the Plateau du Vercors overlooking Grenoble and the view is fabulistic! Trees have started to turn red and yellow, the weather is very mild, and my duties are restricted to teaching ABC to a group of enthusiastic astronomers and cosmologists..! Second advanced course on ABC in the mountains this […]
