[R] error using "predict"

[Xebar Saram]

Hi

I am very new to R (so excuse me in advance if this is pretty trivial)

I am using the predict function to get prediction on a dataset from
another dataset using the follwoing command:


newpredT2003 = predict( object=out.model_T2003, newdata=aodmc_2003 , level = 0 )

yet i get this error:

Error in na.fail.default(list(AOD = c(0.092, 0.081, 0.086, 0.085, 0.09,  :
  missing values in object
Calls: predict ... model.frame.default -> <Anonymous> -> na.fail.default

i think its something simple but cant find any info when googling..can
anyone point me in the right direction on what needs to be done to fix
the errors?

thx

Ethan
