Dear R User, 
Would you give me some hints on why I could not predict using data. format' data.
Here is the example:

ex<-structure(list(env1 = c(182, 163.33, 443.02, 1240.16), env2 = c(1134, 
550, 2111, 2523), env3 = c(24.53, 24.93, 24.71, 21.05), env4 = c(0.05, 
0, 0, 0)), .Names = c("env1", "env2", "env3", "env4"), row.names = c(NA, 
-4L), class = "data.frame")

mod<-bioclim(ex)
pred<-predict(ex,mod)

Error in UseMethod("predict") : 
  no applicable method for 'predict' applied to an object of class "data.frame"

Thanks for your help
KG
