R help - Aug 2016 - Loop over folder files

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?

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,

I removed the data,frame=True...
I obtain this warnings...
Error in read.dta(fuente[i]) : not a Stata version 5-12 .dta file
In addition: There were 50 or more warnings (use warnings() to see the
first 50)

the warnings() throws this
Warning messages:
1: In `levels<-`(`*tmp*`, value = if (nl == nL) as.character(labels) else
paste0(labels,  ... :
  duplicated levels in factors are deprecated
2: In `levels<-`(`*tmp*`, value = if (nl == nL) as.character(labels) else
paste0(labels,  ... :

3: In `levels<-`(`*tmp*`, value = if (nl == nL) as.character(labels) else
