Converts a numeric vector into a factor


This function is an assign DataSHIELD function that coerces a numeric or character vector into a factor


asFactorSimpleDS( = NULL)


the name of the variable that is to be converted to a factor.


The functions converts the input variable into a factor. Unlike ds.asFactor and its serverside functions, ds.asFactorSimple does no more than coerce the class of a variable to factor in each study. It does not check for or enforce consistency of factor levels across sources or allow you to force an arbitrary set of levels unless those levels actually exist in the sources. In addition, it does not allow you to create an array of binary dummy variables that is equivalent to a factor. If you need to do any of these things you will have to use the ds.asFactor function.
