Description

Applies a promoter-inhibitor-model to a given dataset.

Usage

1
2
pim.solve(params, data, model.no=1, 
	silent=FALSE, out2File=FALSE)

Arguments

params

The parameters for the promoter-inhibitor-model as list or vector with following order: a1, a2, a3, a4, T.min.i, T.opt.i, T.max.i, T.min.p, T.opt.p, T.max.p

data

A dataset containing the station ID, the station geographic and the Gauss-Krueger-coordinates of the station, the altitude of the station, the year and the julian day of the budburst and the leafcolouring, outlier information for budburst and leafcolouring and temperature data for modelling. Can be created by using the function data.main.

model.no

The promoter-inhibitor-model to use. See references for more details.

silent

A boolean value determining wether the function should generate output messages or not.

out2File

A boolean value determining wether the output will be stored in log-files.

Details

Applies a promoter-inhibitor-model with given parameters to a given dataset.

Value

A dataset containing the values of the origin dataset and additionally the modelled budburst days.
