I want to aggregate my data. I need a table where I can see "MAD" for each of my participants in each of my three conditions. I tried a lot of functions from mousetrap-package but my trajectories don`t have the same length so most of the time I get warning messages ("In mt_reshape(data = data, use = use, use_variables = use_variables, : For some trials in data[[use2]], no corresponding trials in data[[use]] were found.").
It would be great if anyone could help me - I need this for my master thesis.
