Hi Siyi!

My answer is late but I hope that it is not too late.

Unfortunately, I don't know the reason for the error message.

I suggest that you use the new R package "frontier"  that is available on CRAN 
[1] and R-Forge [2]. It includes the FORTRAN code of Tim Coelli's 
software "Frontier 4.1" (front41.exe). Hence, the R package "frontier" should 
have the same capabilities as "Frontier 4.1".
