[BioC] error while running RMA

[Lang Chen]

Hi, 

I am running RMA on eight ME 430 chips in the cluster(Linux). I got the
following message.

Error in if (a[k]>b[k] return (1) else if (a[k]<b[k] return (-1) :
		missing value where TRUE/FALSE needed
In addition: Warning message:
NAs introduced by coercion
Execution halted

What does it mean? What should I do?

But it works on my PC (Windows 2000 PIII 128M RAM).

Your help is greatly appreciated.
