Dear list members,

I read a shapefile with the function readOGR from the package rgdal, but
the summary of the object show me only some of the levels of the field
"COB_AGROP".  Even I used the argument maxsum=Inf, but it didn´t show me
more levels. How can I see all the levels of my shapefile with the function
summary?

 > summary(cob, maxsum=Inf)
