[R] GIS in R?

[ElSiebo]

Hi
Iam quite new to R and Iam trying to use it for GIS application.
I used the maptools package to load a shapefile 
WVA<-readShapeLines("WVA")

and now I would like to fill gaps in the shape file (missing numbers) with
the numbers from intersecting lines
I have tried with gintersect but I can only get true or false for answer and
not the numbers of the intersected lines...
For example for the first line....
gIntersects(WVA[1,],WVA, byid=TRUE)

Is there another possibility to do this?

Best regards
Franz
