No. There is no limit. However, care should be taken with this. Since Statsframe makes analysis with all given variables, you might want to reduce the number of variables in your dataset, to only those you really wish to evaluate or analyze.
The Statsframe automatically defines the best test to use depending on the type of variables and their distribution.
The “stringsAsFactors” function turns text variables into factors. Depending on the type of analysis you are working on, Statsframe may need to consider the variable as text or as a factor.
No, all variables must have at least one value. If a variable in the dataset is empty, the Statsframe will abort, and the report will be incomplete. Please, remove empty variables.
