[R] Problem with "dea.boot" under R 3.0.1

Hi all,

we conducted a DEA and wanted to correct our efficiency for bias by
bootstrapping with R version 3.0.1. With this version, the package "FEAR"
does not work anymore. Therefore, we used "dea.boot" for bootstrapping.
This, however, returns us negative bias-corrected efficiencies. 

In the past, we have used "boot.fear" and this never delivered any negative
bias-corrected efficiencies. 
Is this a bug of dea.boot or of R 3.0.1? How can we solve this?

Thanks and best regards,
