spaMM (version 2.0.0)

stripHLfit:

Description

Large matrices and other memory-expensive objects may be stored in a fit object. This function removes them in order to reduce the size of the object, particularly when stored on disk. In principle, the removed objects can be regenerated automatically when needed (e.g., for a predict()).

Usage

stripHLfit(object, ...)

Arguments

object

The result of a fit (an object of class HLfit).

…

Further arguments, not currently used.

Value

The input fit objects with some elements removed.

Examples

## Not run: ------------------------------------
# ## rather unconvincing example : quantitative effect is small.
# 
# # measure size of saved object:
# saveSize <- function (object,...) {
#     tf <- tempfile(fileext = ".RData")
#     on.exit(unlink(tf))
#     save(object, file = tf,...)
#     file.size(tf)
#   }
# data(Loaloa)  
# lfit <- fitme(cbind(npos,ntot-npos)~elev1+elev2+elev3+elev4+maxNDVI1+seNDVI
#                    +Matern(1|longitude+latitude), method="HL(0,1)",
#               data=Loaloa, family=binomial(), fixed=list(nu=0.5,rho=1,lambda=0.5))
# saveSize(lfit)                 
# pfit <- predict(lfit,newdata=Loaloa,variances=list(cov=TRUE)) # increases size!
# saveSize(lfit)
# lfit <- stripHLfit(lfit)
# saveSize(lfit)
