Do any #rstats people have good solutions for grabbing data from JSON APIs into a data.frame where the results have an unequal number of fields? And to complicate, some fields are further nested frames?
I'm slowly figuring out a solution that loops over each URL, and then merges using plyr::rbind.fill() - but that doesn't like the nested frames. Looking at flattening the structure now, but I figured I'd check I'm on a good track...
