I'm not a programmer, and often get things wrong, but I trust you'll help rein me in if I get off on a tangent.=20 It would be good if this limitation in ob-R were eliminated. The way I see it, ob-R is designed to handle a subset of the expected input. It coerces a variable into a tsv table, then reads it into R, expecting all cells are filled. At the same time, other babel modules are free to export structures (in the Pascal's triangle example, a list of lists) that orgtbl-to-tsv interprets as a table with empty cells. It would be nice if ob-R could be made to read all the tables that orgtbl-to-tsv is able to create. All the best, Tom=20 --=20 Thomas S. Dye http://www.tsdye.com
