Create a table of `predictors`

A data frame of input data to be used in as predictor values in transition functions.

predictors(df, verbose = FALSE)

df

input data frame, with columns:

pred: String specifying the name of the predictor, e.g. "temp" or "host_den"
pred_subcategory: This column allows specifying predictors for which there are multiple values for a given j_day. Predictor values are sorted by this column in the config set up. This ensures that when accessing a predictor with multiple values for the same j_day, we get a vector of predictor values ordered by this column. A typical use for this column is to specify the host density of each host species.
j_day: Integer specifying the Julian day, or NA for predictors with constant value over time
value: Numeric value of predictor

verbose

Boolean; whether to warn about reordering the df
