[BioC] NOISeq initialization problem

[sara wilson [guest]]

Hi and good day,

I am totally new to R so sorry is my question is so naive.
I am just following the NOISeq tutorial with my own data set.Below is what I have in order to make the readData:

my data:
> head(counts)
             V2 V3  V4  V5 V6  V7 V8  V9
1/2-SBSRNA4   3  5   4   4  2   3  1   1
A1BG        200 93 246 102 86  46 58  85
A1BG-AS1     24 28  16  32 17  10 19  14
A1CF          1  1   1   2  1   0  0   1
A2LD1       100 71  98  97 59 128 88 114
A2M           5  5  23   1  5   6 10   5

> class(counts)
[1] "data.frame"

my factors :
> factors
     sex
1 Female
2 Female
3 Female
4 Female
5   Male
6   Male
7   Male
8   Male

and my length :
> head(mylength)
1/2-SBSRNA4        A1BG    A1BG-AS1        A1CF       A2LD1         A2M 
         23                  916         160                    7         755               60
> class(mylength)
[1] "integer"

when I run the command readData, without the length property it produces the object but with the length property, there is an error. so there should be problem with that but I do not know what is it.
Many thanks in advance.

 -- output of sessionInfo(): 

> noy1 <- readData(data=counts, factors=factors, length= mylength)
> head(noy1)
Error in value[[3L]](cond) : invalid 'row.names' length
  AnnotatedDataFrame 'initialize' could not update varMetadata:
  perhaps pData and varMetadata are inconsistent?

and then without length:

> noy1 <- readData(data=counts, factors=factors)
> head(noy1)
ExpressionSet (storageMode: lockedEnvironment)
assayData: 1 features, 8 samples 
  element names: exprs 
protocolData: none
phenoData
  sampleNames: V2 V3 ... V9 (8 total)
  varLabels: sex
  varMetadata: labelDescription
featureData: none
experimentData: use 'experimentData(object)
