Do you heve any idea why I get after this instruction everywhere false?
> seq (0, 1, by=0.1) == 0.3
 [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE

But after different step it's ok:
> seq(0, 1, by=0.1) == 0.4
 [1] FALSE FALSE FALSE FALSE  TRUE FALSE FALSE FALSE FALSE FALSE FALSE
