seed problem?
Thank you, Jeff! I had that file, and when I removed it, that solved the problem. Now random numbers are really random. Excellent!

Check if you have a .RData file in your R startup directory. It may contain the seed. .RData files (without anything in front of the period) are dangerous... many R users avoid them because they can easily drag in mistakes from previous sessions to plague you.

Hi!
I have Windows 10 on PC and different versions of R. I noticed that
when I executed simulation with R 4.0.3, it gave exactly the same
results next time when I re-opened the program. I didn?t set the seed.
I tested this also with simple ?rnorm(10,100,10)?, and the results were
every time the same, when I re-opened the program. It seems that it
starts with the same seed. R 4.0.0 and 4.0.3 did it, both with 32- and
64-bit versions. But with R Studio the results were every time
different, as they were also different with 3.4.3. This explains, why I
hadn?t noticed this earlier.
I know the function set.seed(), but I wonder, how in the first place
seed can be every time same, if you don?t set it to be. What I read
about seeds, this should be very highly improbable occurence.
Thanks to all developers for what they are doing for common good. I
love R!
