Dear R team,
when using optim with method "CG" I got the wrong $value for the
reported $par.
Example:
f<-function(p) {
if (!all(p>-.7)) return(2)
if (!all(p<.7)) return(2)
sin((p[1])^2)*sin(p[2])
}
optim(c(0.1,-0.1),f,method="CG",control=list(trace=0,type=1))
$par 19280.68
I have a few questions and thoughts regarding class versioning and
serialized S4 class instances.
How is the version argument to setClass is intended to work? It
appears to want an externalptr, but that seems odd to me.
setClass("FOO", representation(x="numeric"), version="1.2.3")
