Create a table of predictors
Description
A data frame of input data to be used in as predictor values in transition
functions.
Usage
predictors(df, verbose = FALSE)
Arguments
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
