[BioC] Unexpected lumiR error message

[jarod07 at ucla.edu]

Hi,
  I am trying to load a large data set using the lumiR() function, the  
data are Illumina Bead Studio output. I get the following error message:

"Error in var(x, na.rm = na.rm) : 'x' is empty"

I am new to R and am not familiar with all the functions, is it  
possible there is a simple fix to this problem?
Best,
Jose
