problem with function project() in package rgdal

Dear all,

I meet a problem with the function project() in package rgdal:

library(rgdal)
data(state)
res <- project(cbind(state.center$x, state.center$y),

+                "+proj=lcc +lat_1=48 +lat_2=33 +lon_0=-100")
Error in project(cbind(state.center$x, state.center$y), "+proj=lcc
+lat_1=48 +lat_2=33 +lon_0=-100") :
   major axis or radius = 0 or not given

sessionInfo()
