Description
It efficiently calculates object's digest.
Usage
1
2
calculate.object.digest(objectname, target.environment = NULL,
flag_use_attrib = TRUE, flag_add_attrib = FALSE)
Arguments
object
The name of the object to calculate digest of. Object must exist in
.GlobalEnv.
Details
It treats data.frame objects separately. Rather than invoking digest::digest()
on them directly, it first splits the object into individual columns, sorts them,
calculates the
digest on each column separately (trying to do that in parallel), and merges the
results into one string, that is digested again.
Value
Lowercase MD5 string with the digest of the object
