@etiennebacher I just re-wrote the benchmark script in mostly base R. No action need. Just a FYI. |

Thanks, I had tried with data.table but unnesting was surprisingly unfriendly compared to tidyverse. |

Yeah, I think the pattern in library(data.table)
url <- "https://vincentarelbundock.github.io/Rdatasets/csv/HistData/Guerry.csv"
dat <- na.omit(fread(url))
nested = dat[, list(data=list(.SD)), by=Region]
unnested = nested[, data[[1]], by = Region]
head(nested, 2)
> Region data
> <char> <list>
> 1: E <data.table[17x23]>
> 2: N <data.table[17x23]>
