Is this a bug?
Yes. If you look inside the saved file it contains ..., call = dist(x = USArrests), ... When this is reread, an attempt is made to evaluate the call. Some kind of quoting is needed.
I do this:
library(mva)
data(USArrests)
d <- dist(USArrests)
dump("d", "tst")
q()
I restart R and do this:
source("tst")
And I get:
Error in as.matrix(x) : Object "USArrests" not found
