Each 12 reference class is associated with a C++ class of the 13 same name. As is customary, the generator object for 14 each class has the same name as the class. 15} 16\section{Extends}{ 17 All reference classes extend and inherit methods from 18 \code{"\linkS4class{envRefClass}"}. Furthermore, 19 \code{"glmResp"}, \code{"nlsResp"} and \code{"lmerResp"} 20 all extend the \code{"lmResp"} class. 21} 22\note{ 23 Objects from these reference classes correspond to 24 objects in C++ classes. Methods are invoked on the C++ 25 classes using the external pointer in the \code{ptr} 26 field. When saving such an object the external pointer 27 is converted to a null pointer, which is why there are 28 redundant fields containing enough information as R 29 objects to be able to regenerate the C++ object. The 30 convention is that a field whose name begins with an 31 upper-case letter is an R object and the corresponding 32 field whose name begins with the lower-case letter is a 33 method. Access to the external pointer should be through 34 the method, not through the field. 35} 36\examples{ 37showClass("lmResp") 38str(lmResp$new(y=1:4)) 39showClass("glmResp") 40str(glmResp$new(family=poisson(), y=1:4)) 41showClass("nlsResp") 42showClass("lmerResp") 43str(lmerResp$new(y=1:4)) 44} 45\seealso{ 46 \code{\link{lmer}}, \code{\link{glmer}}, 47 \code{\link{nlmer}}, \code{\linkS4class{merMod}}. 48} 49\keyword{classes} 50 51
