IMPORTR: Stata module to import R data files (.Rdata,.Rda,.Rds) into Stata over an R or Python bridge

Eric Booth

Statistical Software Components from Boston College Department of Economics

Abstract: .Rdata and .Rds files are compressed binary objects in R's own serialization format, so there is no pure-Stata way to read them; something outside Stata has to do the decoding. importr takes a dual-bridge approach so that it works on machines with R and on machines without it. It first tries R, converting the file through the haven package; if that does not produce a dataset it falls back to Stata's built-in Python integration, reading with pyreadr and writing with pyreadstat. Either path lands the data in memory, and the bridge that succeeded is reported. Handles .Rdata, .Rda, and .Rds.
