On the R plotting thing - do note that the gold standard plotting package in R, ggplot2, is a package/module - not in core. Likewise dplyr is an R package, not core. And they came into R quite late - well after it was a dominant datasci language. So, I’m not sold yet on Julia itself being insufficient. I will be very happy when Gadfly.jl, Query.jl and DataFramesMeta.jlare at an R level though. DataFrames.jlis awesome already, post 0.11.
Second, I’m getting rather tired of hearing about how upset the “hordes” will be, and I’m not even a committer. Not to ignore future users, but in my opinion this constant worrying and hypothesizing really feels unhealthy and could even be warping the focus of the essential basics. Kudos to the core team for keeping that balance right.
