ManagerObject-class: S4 Class "ManagerObject"

In lucabutikofer/WofostR: R Implementation of Wofost Crop Growth Algorithm

Description

Object containing managements instructions used to run a sequence of crops simulation in succession for the same location (e.g. a crop rotation or the same crop over multiple years).

Slots

cropVarSequence:

Character vector containing the names of the crop varieties in the desired succession. Must be in the format "cropName-varName". Type "cropVarList" for a list of crop and variety names.

cropStartTypes:

Character vector of same length as cropSequence containing the crop start type (i.e. "sowing" or "emergence")

cromStartDate:

Character vecotr of same length as croRotation containing start Dates for each crop. The first element is ignored and the first crop will start at "sequenceStart".

cropFinish:

Character vector of same length as cropRotation containing either a crop stage (e.g. "maturity") or a date in the format "YYYY/MM/DD". Where specified, date will take priority over corp stage and can be used to regulate long rotation series.

spacing:

Numeric vector of same lenaght as cropSequence. number of days after previous step when new crop is started. The first crop will be started spacing[1] days after sequenceStart. In most cases spacing[1] = 0.

Examples

ManagerObject(
  cropSequence = c(
    'barley-Spring_barley_301',
    'millet-Millet_VanHeemst_1988',
    'maize-Grain_maize_201'),
  sequenceStart = '2010/04/16',
  sequenceFinish = '2012/01/01',
  cropStartType = c('sowing', 'sowing', 'sowing'),
  cropStartDate = c(NA, '2011/04/16', NA),
  cropFinish = c('maturity','2011/05/16','maturity'),
  spacing = c(0, NA, 10 )
)
