[R] Merging listed dataset into one

[Seungyeul Yoo]

Hello,

I'm wondering how I can merge two featuresets into one.

My dataset is two sets of microarray data and it looks like followings:

> rawData
$v1
TilingFeatureSet (storageMode: lockedEnvironment)
assayData: 2197815 features, 59 samples 
  element names: channel1, channel2 
protocolData
  rowNames: LT290677RU_D1_2011-02-16 LT286300LU_D1_2010-07-24 ...
    LT003990RU_D1_2010-11-04 (59 total)
  varLabels: filenamesChannel1 filenamesChannel2 dates1 dates2
  varMetadata: labelDescription channel
phenoData
  rowNames: LT290677RU_D1_2011-02-16 LT286300LU_D1_2010-07-24 ...
    LT003990RU_D1_2010-11-04 (59 total)
  varLabels: sampleID tissue ... Annotation (5 total)
  varMetadata: labelDescription channel
featureData: none
experimentData: use 'experimentData(object)'
Annotation: pd.feinberg.hg18.me.hx1 

$v1.1
TilingFeatureSet (storageMode: lockedEnvironment)
assayData: 2197815 features, 17 samples 
  element names: channel1, channel2 
protocolData
  rowNames: LT282562RM_D1_2010-11-22 LT280646RU_D1_2010-11-22 ...
    LT093297LU_D1_2010-11-12 (17 total)
  varLabels: filenamesChannel1 filenamesChannel2 dates1 dates2
  varMetadata: labelDescription channel
phenoData
  rowNames: LT282562RM_D1_2010-11-22 LT280646RU_D1_2010-11-22 ...
    LT093297LU_D1_2010-11-12 (17 total)
  varLabels: sampleID tissue ... Annotation (5 total)
  varMetadata: labelDescription channel
featureData: none
experimentData: use 'experimentData(object)'
Annotation: pd.feinberg.hg18.me.hx1 

I want to merge rawData$v1 and rawData$v1.1 since they are consistent each other.

I was trying to use "merge" function as merge(rawData$v1, rawData$v1.1) but it failed with error as

Error in as.data.frame.default(x) :
  cannot coerce class 'structure("TilingFeatureSet", package = "oligoClasses")' into a data.frame
Calls: merge ... merge.default -> merge -> as.data.frame -> as.data.frame.default

Can you please help with some advices?

Thanks,

Best regards,
