When given objects of class `panelPomp`, `unit_objects()` returns a `list` of `pomp` objects. `window()` returns a `panelPomp` object with adjusted times. ```[``` returns a `panelPomp` object. ```[[``` returns a `pomp` object. `specific()` returns unit-specific parameters as a numeric matrix or vector `shared()` returns shared parameters from a panelPomp object ## Methods - **coef**: Extracts coefficients of `panelPomp` objects. - **coef<-**: Assign coefficients to `panelPomp` objects. - **length**: Count the number of units in `panelPomp` objects. - **names**: Get the unit names of `panelPomp` objects. - **toParamList**: Converts panel coefficients from vector form to list form. - **window**: Subset `panelPomp` objects by changing start time and end time. - **`[]`**: Take a subset of units. - **`[[]]`**: Select the pomp object for a single unit. - **specific**: Extracts the `specific` coefficients. - **specific<-**: Assigns the `specific` coefficients. - **shared**: Extracts the `shared` coefficients. - **shared<-**: Assigns the `shared` coefficients. ## Examples ```r ## access and manipulate model parameters and other features prw <- panelRandomWalk() coef(prw) # replace coefficients coef(prw) <- c(sigmaX=2,coef(prw)[-1]) coef(prw) length(prw) names(prw) # convert vector-form parameters to list-form parameters toParamList(coef(prw)) ## summaries of objects print(prw) show(prw) ## access underlying pomp objects unit_objects(prw) ## select windows of time window(prw,start=2,end=4) ## subsetting panelPomp objects prw[1] # panelPomp of 1 unit (first unit of prw) prw[[2]] # pomp object corresponding to unit 2 of prw # access and manipulate model parameters and other features specific(prw) # replace unit-specific coefficients specific(prw) <- c("sigmaX[rw1]"=2) specific(prw) # access and manipulate model parameters and other features shared(prw) # replace unit-specific coefficients shared(prw) <- c('sigmaY'=2) shared(prw) ``` ## See Also Other panelPomp methods: `as()` ## Author(s) Carles Bret , Aaron A.
