show_constant

Show all variables with no variation in their values within each data frame
of the list of data frames (except the ones in the info list).
This function is useful for identifying unnecessary variables before
running an experiment.
It allows checking for columns with any unchanging value or only
a specific value.

oTree

Efficiently manage and process data from 'oTree' experiments.
Import 'oTree' data and clean them by using functions that handle
messy data, dropouts, and other problematic cases. Create IDs,
calculate the time, transfer variables between app data frames, and
delete sensitive information. Review your experimental data prior to
running the experiment and automatically generate a detailed summary
of the variables used in your 'oTree' code. Information on 'oTree' is
found in Chen, D. L., Schonger, M., & Wickens, C. (2016)
