Errors occured

Hi all,

Has anybody have the experience in the errors:

Error in data.frame(..., check.names=FALSE): arguments imply differing number of rows: 343,15

This is the error occured in the middle of the program. I don't think the data frame has any problem, if there is problem with the program, why it happened in the middle?

Does anybody have such an experience? It seems so weird to me.

Thanks a lot!
