[BioC] segmentation error in pamr.knnimpute

[Alice Le Bars]

Dear all,

I am in trouble with pamr.knnimpute (library pamr)
When I use this function in a "for" loop with matrix  of  4 samples at 
each loop,  R does a segmentation fault which ends with a fatal error (R 
close itself) I used this function previously with 8 samples and 1327 
genes and it worked.
I try my script using  Windows and on server using Linux, still  error 
remains (so this mustn't be a ressource error, I think)
He breaks on knnimp function
The dimensions of my tables are 1337*4 and 1327*4 and I use a k=10 for 
the number of neighbors. 
My main problem is that the error is not permanent, sometimes (but not 
generally) it may work, and when I have the error it could be either on 
the first or on the second table .

Thanks for helping.
Alice.
