{brickr} updated so it's easier to program your own 3D models. Even better... you can now do machine learning with LEGO & #brickr. Here's a random forest model! #rstats #rayshader https://t.co/vBK0A70PTl pic.twitter.com/Mi31sYX3F8

Hey there #RStats folks, everybody makes mistakes and R is not famous for its clear error messages... So I've started a little package to help with that: https://t.co/boy2S3VuYR
Feel free to add your own errors and messages! https://t.co/auh5OUTbuP pic.twitter.com/xVMKAoDjOW
