Just created this video which gives a step-by-step introduction to my OneR package (on CRAN)!

Please tell me what you think and please share - Thank you :-)

I thought "No way, you must be kidding me!" - but it is actually true!

An episode of the 1950s western TV series 'Trackdown' featured a character named Walter Trump who claimed he would build a wall in order to protect a town from the end of the world.

Creature of nightmares

This is the scariest insect I've ever seen: the giant toothed longhorn beetle from the Amazon basin in Ecuador.   It's not as big as it looks here, but it's big: one of the biggest beetles in the world, up to 17 centimeters long.  (That's half a foot, for you Americans.)  Its larvae are even longer! 

+Gil Wizen, who photographed this monster, writes:

Encountering this species was one of my highlights for the year. I know Macrodontia cervicornis very well from museum insect collections. It is one of the most impressive beetle species in the world, both in size and structure. But I never imagined I would be seeing a live one in the wild! Well let me tell you, it is hard to get over the initial impression. The male beetle that I found was not the biggest specimen, but the way it moved around still made it appear like nothing short of a monster. This species is very defensive, and getting close for the wide angle macro shot was a bit risky. The beetle responds to any approaching object with a swift biting action, and those jaws are powerful enough to cut through thick wooden branches, not to mention fingers!

Check out his favorite photos of the year:

Nice and concise overview of object orientation in R

Whilst many R users are be adept at creating their own functions, it seems that there is room for many more to take advantage of ...

Hadley: "The tidyverse is a great place for people to start, he said, but knows that "in order to do real work you need to go out of the tidyverse."
 
Shiny creator said he's working on an R package to extend reactivity functionality, such as returning a prior value. A bit more info in my blog from today's RStudio conference: http://cwrld.us/rconf17#Rrxtools
I'll be sharing the most interesting things I hear, see and learn at this week's big R event.

+Dirk Eddelbuettel: Interesting, isn't it: Hadley: "The tidyverse is a great place for people to start, he said, but knows that "in order to do real work you need to go out of the tidyverse."... you remember our conversation about this in Chicago? ;-)
