I want to read a data record into R. I downloaded the script and the data set and got the following error message:
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : scan() expected 'a logical', got '3'

What should i do?
look for your help!

This may be an issue with the file encoding that R uses for the import script.

First thing you may want to try is opening the script as UTF-8.

Second thing: The API import (that actually downloads the script from the server, and the script then tells R to download the data from the server) also often circumvents the issue: Click the button to enable the API download, then copy the one-liner into R/RStudio, then run the line.

The only thing I can offer, then, is taking a look at the data personally. If you would like me to download the data an look for the reason of the problem, please tell me the name of the survey. I can create an administrator login für the survey project then.

Ahhm ... I did not do anything ... did not yet find the time. But if it's working now, that's great :)

Would you mind telling us the solution as well? Might well be that someone else steps over the same issue...

"One of the columns that have been specified to be logical contains a 3. Try removing the colClasses= argument. Another thing to try is fread from data.table using no other arguments "  I removed the colClasses and worked:)

Interesting ... possibly a relict from a time when the question had a different question time. Good to know anyway, thank you!
