[R] Error in rownames

[Chris Jackson-Jordan]

Dear fellow R users,

I am trying to run the random forest and Yaimpute packages in R to
impute a grid to project in a gis. However, after running the
imputation I keep getting an error in the rownames. This sounds simple
enough, but I cannot figure out what these rownames are reffering to.
Any ideas? I am fairly new to R so im sure it is an easy fix. Any help
would be awesome.

Thanks,

Chris
