TIMP (version 1.5)

dat-class: Class "dat" for model and data storage

Description

dat is the super-class of other classes representing models and data, so that other model/data classes (e.g., kin and spec for kinetic and spectral models respectively) also have the slots defined here. These slots may be specified in the ... argument of the initModel function.

Objects from the Class

Objects from the class can be created by calls of the form new("dat", ...) or dat(...), but most are most often made by invoking another function such as readData or initModel.

 k <- c(.5, 1)
 t <- seq(0, 2, by = 2/50)
 C[, 1] <- exp( - k[1] * t)
 C[, 2] <- exp( - k[2] * t) 
 E <- matrix(nrow = 51, ncol = 2)
 wavenum <- seq(18000, 28000, by=200)
 location <- c(25000, 20000)
 delta <- c(5000, 7000)
 amp <- c(1, 2)
 E[, 1] <- amp[1] * exp( - log(2) * (2 * (wavenum - location[1])/delta[1])^2)
 E[, 2] <- amp[2] * exp( - log(2) * (2 * (wavenum - location[2])/delta[2])^2)
 sigma <- .001
 Psi_q  <- C
 # initialize an object of class dat 
 Psi_q_data <- dat(psi.df = Psi_q, x = t, nt = length(t), 
 x2 = wavenum, nl = length(wavenum))

 # initialize an object of class dat via initModel 
 # this dat object is also a kin object
