# create a file to convert
export(mtcars, "mtcars.dta")
# convert Stata to CSV and open converted file
convert("mtcars.dta", "mtcars.csv")
head(import("mtcars.csv"))

export(mtcars, "mtcars.csv", format = "tsv")
convert("mtcars.csv", "mtcars.csv", in_opts = list(format = "tsv"))
# convert serialized R data.frame to JSON
