Hi,

I would like to know all available data types (valueType in dictionary file) that can be recognized by opal. In my test, factor (categary) variables cannot be recognized, am I right?

Regards,

Hank

Hi,

See documentation: http://opaldoc.obiba.org/en/latest/variables-data.html#value-types

Factor is not a value type. The equivalent is a variable with categories, whatever is its value type (described above).

Hi Yannick,

Thanks for the table and interpretation. I would use boolean or integer for data uploading and then transformed them to factor in R manually.
