Ahh, of course! thanks!
...and in case a future R user wants to solve this problem:
languages <- read.csv("languages.csv", header=TRUE)
languages <- merge(
languages[c('ID', 'Family_ID', 'Name')],
languages,
by.x="Family_ID", by.y="ID",
all.x=TRUE,
suffixes=c(".Language", ".Family")
)
That's just a self-join of languages.csv on Family_ID away!
