[BioC] Error of pamr.knnimpute

[washiot+1 at gmail.com]

Dear all,

I am trying to use pamr.knnimpute with Agilent Microarray data which
consist from 137 colums (samples) and 23653 rows (probes).
These data values were calculated in log ratio, and 212 of them were "NA".

I tried to run pamr.knnimpute with this dataset.
But an error occurred as below.

> pamr.knnimpute(tmp2)
Error in rep(1, p) : invalid 'times' argument


Would you tell me how to fix this problem ?


Sincerely yours,
