I was installing the 'diffobj' package into TERR and got an error from the
call
StyleSummary <- setClass("StyleSummary",
slots=c(container="ANY", body="ANY", map="ANY"),
prototype=list(
container=function(x) sprintf("\n%s\n", paste0(x, collapse="")),
body=identity,
detail=function(x) sprintf("\n%s\n", paste0(" ", x, collapse="")),
map=function(x) sprintf("\n%s", paste0(" ", x, collapse="\n"))
))
because the prototype contained components not in the slots list. R does
not complain about the mismatch, but new("StyleSummary") does name make
something with a 'detail' slot. Should this be an error?
I suspect that the package writer intended to include 'detail' in the slots
argument.
