Deparse list structure from month specification into single calls, call an aggregating function to collect the data, and return a parameter set for calibration. In general, the months must be specified as a list or nested list structure. Possible cases are: list() list(...) list(list(...)) list(list(...), list(...), ...)
tc_design(selection, climate, check_2 = TRUE)
a data.frame
the list structure to specify the month selection
the climate data as returned by make_pmat
should there be a check for less than 2 variables in the design matrix?
