  data.out = FALSE, stata.path = getOption("RStata.StataPath",
  stop("You need to set up a Stata path; ?chooseStataBin")),
  stata.version = getOption("RStata.StataVersion",
  stop("You need to specify your Stata version")),
  stata.echo = getOption("RStata.StataEcho", TRUE), ...)

Arguments

src	character vector of length 1 (path to .do file) or more (a set of stata commands). See examples.
data.in	data.frame to be passed to Stata
data.out	logical value. If TRUE, the data at the end of the Stata command are returned to R.
stata.path	Stata command to be used
stata.version	Version of Stata used
stata.echo	logical value. If TRUE stata text output will be printed

Examples

## Not run: 
## Single command
stata("help regress") #<- this won't work in Windows dued to needed

## Many commands
stata_src <- '

version 10
set more off
sysuse auto
reg mpg weight

'
stata(stata_src)

## External .do file
stata("foo.do")

## Data input to Stata
x <- data.frame(a = rnorm(3), b = letters[1:3])
stata( "sum a", data.in = x)

## Data output from Stata (eg obtain 'auto' dataset)
auto <- stata("sysuse auto", data.out = TRUE)
head(auto)

## Data input/output
(y <- stata("replace a = 2", data.in = x, data.out = TRUE))
