seed problem?
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! Mika Hamari [[alternative HTML version deleted]]
