Hello everyone,

I run the exmaple in GEOquery documentation but there are some errors. I can't get correct sampleNames.

I have tried several different datasets and all get error.But my friend use  older versions can get same result wtih documentation.I think there are some problem in my R enviroment.

Is this an problem in the GEOquery or my fault ?


my code:

gsm <- getGEO("GSE2553", GSEMatrix=TRUE)

assayData: 12599 features, 181 samples 
  element names: exprs 
protocolData: none
  sampleNames: 0.2701103 0.3925373 ... 1.4989663 (181 total)   #error  The correct output is  GSM48681 GSM48682 ...

  varLabels: title geo_accession ... data_row_count (30 total)

Yes, the "bug" here is a change in behavior of read_tsv and friends in readr. See
