#RStats DemoScene Update: Writing old skool demo effects and figuring out how some of them worked is a whooooole heap of fun! :)

The R version of Oxygene's STNICCC2000 demo (a 90secone pre-digested 3d anim) renders to an mp4 in 4 seconds using {nara} + {mp4encoder}

A while back, the journal Cognitive Science asked the field for provocative proposals for the next phase of the cognitive sciences. Most of the submissions are now collected here: co-mind.org/progress-puzzles-p

How weird. Two of my worlds collide. The new OpenBSD artwork is based on Louis Wain's paintings he did while he was a patient at the Bethlem Hospital.

I realise I'm talking to a niche audience here, but er, hello fellow BSD Unix / South East London mental health fans

DELIGHTED to see the BMJ @bmj_latest saying today that they will require papers to share their code.
bmj.com/content/382/bmj.p1609

HUGE milestone for reproducibility, quality, and efficiency.

Here's our BMJ editorial on why code sharing matters, from 2019:

Faux 1.2.1 is now out on CRAN (sorry for letting it get archived) #rstats

The biggest change is the addition of a new function rmulti() for simulating multivariate non-normal distributions using the NORTA method (normal-to-anything). I've run extensive tests, but it's still experimental, so let me know if you have any problems.

debruine.github.io/faux/articl

Code for the rmulti() function and a plot of the resulting uniform by poisson distributions:

dat <- rmulti(n = 1000, 
              dist = c(uniform_var = "unif",
                       poisson_var = "pois"),
              params = list(uniform_var = c(min = 0, max = 100),
                            poisson_var = c(lambda = 3)),
              r = 0.5)

get_params(dat)
#>      n         var uniform_var poisson_var  mean    sd
#> 1 1000 uniform_var        1.00        0.49 50.62 28.67
#> 2 1000 poisson_var        0.49        1.00  2.98  1.75
