Consistency of serialize(): please enlighten me
Hi,
I am puzzled with serialize(). It comes down generating identical
hash codes for (apparently) identical objects using digest::digest(),
which in turn relies on serialize(). Here is an example illustration
the issue:
ser <- function(object, ...) {
list(
names = names(object),
namesRaw = charToRaw(names(object)),
ser = serialize(names(object), connection=NULL, ascii=FALSE)
)
} # ser()
# Object to be serialized
key <- key0 <- list(abc="Hello");
# Store results
d <- list();
# 1. As is
d[[1]] <- ser(key);
# 2. Set names and redo (hardwired: identical...
