[Bioc-sig-seq] Inverted definitions of "precede" and "follow" (IRanges) ?

[Ulrike Goebel]

Hello,

"precede" and "follow" seems to do just  the opposite of  what is 
described  in the help page:

 > test <- IRanges(start=c(1,6,20), end=c(5,22,40))
 > precede(test)
[1]  2 NA NA
These are the ranges that *follow* the query ranges ..

 > follow(test)
[1] NA  1  1
.. and these are the preceding ranges ...

Is this meant to be like this ?

Best, Ulrike
