[R-sig-Geo] About "as.CRSPts" function of proj4R

[Hisaji ONO]

Hello.

 I've tried to execute "example(as.CRSPts)" of proj4R package.

 But I've got following error message.

a.CRSP> data(state)

a.CRSP> state.xy <- xyPts(state.center$x, state.center$y)

a.CRSP> state.xy.cot <- state.xy[state.xy at x >= -121]

a.CRSP> state.xy.cot.ll27 <- as.CRSPts(state.xy.cot, CRS =
CRS("+proj=latlong +datum=NAD27"))
Error in asMethod(object, Class, value) : couldn't find function
".InhSlotNames"

 Could you give any suggestion?


 Regards.
