Welcome to the fourth post in the repulsively random R ramblings series, or R⁴ for short.

My twitter feed was buzzing about a nice (and as yet unpublished, ie not-on-CRAN) package https://github.com/dirkschumacher/thankr by Dirk Schumacher which compiles a a list of packages (ordered by maintainer count) for your current session (or installation or …) with a view towards saying thank you to those whose packages we rely upon. Very nice indeed.

I had a quick look and run it twice … and had a reaction of ewwww, really? as running it twice gave different results as on the second instance a boatload of tibblyverse packages appeared. Because apparently kids these day can only slice data that has been tidied or something.

So I had another quick look … and put together an alternative version using just base R (as there was only one subfunction that needed reworking):

source(file="https://raw.githubusercontent.com/dirkschumacher/thankr/master/R/shoulders.R")
format_pkg_df <- function(df) { # non-tibblyverse variant
    tb <- table(df[,2])
    od <- order(tb, decreasing=TRUE)
    ndf <- data.frame(maint=names(tb)[od], npkgs=as.integer(tb[od]))
    colpkgs <- function(m, df) { paste(df[ df$maintainer == m, "pkg_name"], collapse=",") }
    ndf[, "pkg"] <- sapply(ndf$maint, colpkgs, df)
    ndf
}

Running this in the ESS session I had open gives:

and for good measure a screen is below:

I think we need a catchy moniker for R work using good old base R. SoberVerse? GrumbyOldFolksR? PlainOldR? Better suggestions welcome.
