I was addressing the
Exactly, from ?.Random.seed:
"In the underlying C, .Random.seed[-1] is unsigned; therefore in R
.Random.seed[-1] can be negative, due to the representation of an
unsigned integer by a signed integer. "
and
"It can be saved and restored, but should not be altered by the user. "

HI Rui,
Thank you so much for getting back to me!
I did implement your idea (see attach):
ax.11.text <- element_text(size = 10)
ay.11.text <- element_text(size = 10)
p<-ggplot(data=toplot, aes(x=cat, y=props)) +
geom_bar(stat="identity",width=0.5, fill="steelblue")+
geom_errorbar(aes(ymin=pro
I am no expert on this specific algorithm, but there is no "32-bit unsigned
integer" type in R. Presumably the interpretation of those negative numbers in
the C code is as if they were unsigned while R presents them as if they were
signed because it cannot do otherwise.
AFAIK you need to use se

Dear R users,
inspecting .Random.seed for the Mersenne Twister (MT) I find (many)
negative values for the
624 values of the initial state of the generator.
It seems to me that this is a bug (an unsigned integer mapped to a signed
integer ?),
since, to my understanding, the R version of MT should
