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:

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

output：

$`GSE2553_series_matrix.txt.gz`
