R help - Apr 2009 - Using spdep example data and R code : bbox should never contain infinite values

Hi,

I am facing with a problem when running a code against the sample data from
spdep. I am getting

"SpatialPoints" object : bbox should never contain infinite values
In additionl Warning Messages:
1. In min(x): no non-missing arguments to min; returning Inf
2. In max(x): no non-missing arg...


The code I am trying to execute:

sidgams<-opgam<data=as(nc, "data.frame"), radius=30, step=10,
alpha=.002)
gampoints<-SpatialPoints(sidsgam[,c("x","y")]*1000,
  CRS("+proj=utm +zone=18 +datum=WGS84"))

The input dataset is a modified polygon (in WGS datum) of North Carolina
that comes with spdep, but using some other additional fields for
calculation.

I would be very happy to receive a suggestion on corecting this.

Thanks!

Dejan
