sorry if it has already been discussed but i can't understand this:

> seq(0.1,1,by=0.1)
 [1] 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0
> match(0.1,seq(0.1,1,by=0.1))

[1] 1
> match(0.2,seq(0.1,1,by=0.1))

[1] 2
> match(0.3,seq(0.1,1,by=0.1))

[1] NA
> match(0.4,seq(0.1,1,by=0.1))

[1] 4

> R.version
