subset(x, ...) <- value
"subset"(x, element, states, etas, series, times, ...)subset generic in base, and most likely not
that useful (compared to [<-.SSModel).Deviance.KFS was removed as it was mostly useless. The value was not a $-2*(logL-logL*)$ where $L$ is the likelihood and $L*$ is the saturated likelihood. Instead it was based on the conditional likelihood $p(y|theta)$ i.e. it disregards the effect of hidden states. Therefore the value returned by this function did not make much sense in non-GLM setting.
