[R] Surprisingly large amount of memory used by tibble with lots of nested tibbles within

I'm using the Tidyverse group_nest() function to nest data about families and people within households, and have found that this seems to use astonishing quantities of memory.

[R] Using R and the Tidyverse for an economic model

I've been translating an economic model from Python into R, and I thought members of the list would like to see a presentation I've written about it. I've blogged this at http://www.j-paine.org/blog/2018/03/r-taxben-a-microsimulation-economic-model-in-r.html , and the presentation itself is a slide

[R] How to install Tidyverse on Ubuntu 17.04? Getting gcc errors for -fstack-protector-strong and -Wdate-time

I'm running Ubuntu 17.04 and R 3.4.1. I installed the latter yesterday, so I presume it's the latest version. I want to install Tidyverse, which I've spent many happy hours with under Windows.

[R] SASxport function read.xport gives error "object 'w' not found"

SAS correctly when generating it. Other files containing purely numeric data from the same author converted OK, using analogous calls to read.xport . Googling the error didn't find anything. Thanks, Jocelyn Ireson-Paine 07768 534 091 http://www.jocelyns-cartoons.co.uk __

[R] How can I run package ca (correspondence analysis), which needs rgl, without X11?

using ImageMagick.) So if ade4 can do this, ca ought to be able to. How can I make it? I don't mind ca complaining when it indeed does need X11, but couldn't the dependency check be postponed until runtime, so as not to spoil things for people to whom it'
