Hello,

The op could also use package sos to find that and other packages to read
stata files.

install.packages("sos")

library(sos)
findFn("stata")
found 374 matches;  retrieving 19 pages
2 3 4 5 6 7 8 9 10

The first package is readstata13 but there are others.

Hope this helps,

Dear Juan

If this is a Stata 13 file the package readstata13 available from CRAN may
be of assistance.

Hello,

That argument doesn't exist, hence the error.
Read the help page ?read.dta more carefully. You will see that already
read.dta reads into a data.frame.

Hope this helps,

Hi
I need to apply some code over some stata files that are in folder.
I've wrote this

library(foreign)

fuente=list.files("C:/Users/Jceccarelli/Bases/Stata", pattern="dta$",
full.names=FALSE)

for (i in 1:length(fuente)){

xxx=read.dta(fuente[i], to.data.frame=TRUE)


}

But i get this error

Error in read.dta(fuente[i], to.data.frame = TRUE) :
unused argument (to.data.frame = TRUE)

What am i doing wrong?
