"Abridged" description of SpatialPolygonsDataFrame objects?

If "d" is a SPolyDF

## first row/object
d[1,]
str(d[1,])

## the first Polygons object itself  (Polygons can be of many)
d at polygons[[1]]
str(d at polygons[[1]])

## the first Polygon in the first Polygons object
d at polygons[[1]]@Polygons[[1]]
str(d at polygons[[1]]@Polygons[[1]])

Hi!

If I do str(a) where a is a SpatialGridDataFrame, I get
a description of the structure that is readable,
but for SpatialPolygonsDataFrame the output of str() is
too long. Is there any way of looking at the
structure of a SpatialPolygonsDataFrame object just down to
a certain level? For example, not getting the structure of the
each polygon but getting the first one only.

Thanks
