Dear Peter,
Also thank you for your quick reply. I did the following with no positive
result:
library(foreign)
read.dta(choose.file(C:\Rklein))
Error: unexpected input in "read.dta(choose.file(C:\"
> read.dta(choose.file("C:\Rklein"))
Error in grep("^(http|ftp|https)://", file) :
could not find function "choose.file"
In addition: Warning messages:
1: '\R' is an unrecognized escape in a character string
2: unrecognized escape removed from "C:\Rklein"
The Rklein file is indeed .dta.
So what is the next step I can do?
Best regards, Rob Bakker
