Function summary
summarizes the model's output in different temporal steps (i.e. weekly, annual, ...).
Usage
# S3 method for class 'spwb'
summary(
object,
freq = "years",
output = "WaterBalance",
FUN = sum,
bySpecies = FALSE,
months = NULL,
...
)
# S3 method for class 'pwb'
summary(
object,
freq = "years",
output = "WaterBalance",
FUN = sum,
bySpecies = FALSE,
months = NULL,
...
)
# S3 method for class 'growth'
summary(
object,
freq = "years",
output = "WaterBalance",
FUN = sum,
bySpecies = FALSE,
months = NULL,
...
)
# S3 method for class 'fordyn'
summary(
object,
freq = "years",
output = "WaterBalance",
FUN = sum,
bySpecies = FALSE,
months = NULL,
...
)
Arguments
- object
An object of class
spwb
,pwb
,growth
orfordyn
.- freq
Frequency of summary statistics (see
cut.Date
).- output
The data table to be summarized. Accepted values are the path to data tables in
object
, such as 'WaterBalance', 'Soil', 'Stand' or 'Plants$LAI'. It is also possible to use strings like 'Transpiration' and the function will interpret it as 'Plants$Transpiration'.- FUN
The function to summarize results (e.g.,
sum
,mean
, ...)- bySpecies
Allows aggregating output by species before calculating summaries (only has an effect with some values of
output
). Aggregation can involve a sum (as for plant lai or transpiration) or a LAI-weighted mean (as for plant stress or plant water potential).- months
A vector of month numbers (1 to 12) to subset the season where summaries apply.
- ...
Additional parameters for function
summary
.
Note
When applied to fordyn
objects, the summary function can be used to gather the results of different yearly steps into a single table while keeping a daily resolution (i.e. using freq = "days"
.

#Initialize input
