MedianNorm function giving NA values

[Swati Krishna]

Hi,

   I am using a RSEM count matrix with 20531 rows of genes and 94 samples.This the output of str() function with input as my count matrix

>str(rawdata)

 num [1:20531, 1:94] 0 10.5 28.6 3 129.7 ...

 - attr(*, "dimnames")=List of 2

  ..$ : chr [1:20531] "?|100130426" "?|100133144" "?|100134869" "?|10357" ...

  ..$ : chr [1:94] "D1" "D2" "D3" "D4" ...

But when I run the next step of median normalisation,the output is only NA values. Could anyone please suggest a solution to this problem .

Thank you
