There is a new package to import Stata 13 files into a data.frame in R.
Install the package and read a Stata 13 dataset with read.dta13():
install.packages("readstata13")
library(readstata13)
dat <- read.dta13("TEAdataSTATA.dta")
Update: readstata13 imports in version 0.8 also files from Stata 6 to 14
