Hello, I used GEOquery to get GEOdata, but Meta() function didn't work. The warning information showed that "Error in function (classes, fdef, mtable)  :   unable to find an inherited method for function "Meta", for signature "list". How can I do for this situation? The R scripts: > library(GEOquery)> gse1402<- getGEO("GSE1402", GSEMatrix = TRUE) Found 1 file(s)GSE1402_series_matrix.txt.gztrying URL 'ftp://ftp.ncbi. nih.gov/pub/geo/DATA/SeriesMatrix/GSE1402/GSE1402_series_matrix.txt.gz 'ftp data connection made, file length 3193548 bytesopened URL==================================================downloaded 3.0 Mb File stored at: /var/folders/Sv/SvMFI445FgqzS1ou834jU++++TI/-Tmp-//Rt mp4tQQtq/GPL8300.soft> Meta(gse1402)Error in function (classes, fdef, mtable)  :   unable to find an inherited method for function "Meta", for signature "list" Thank you for your great help!

Please read posting guide, and supply sessionInfo() result to allow diagnosis of your problem. Be sure you are using R 2.10 and the current version of GEOquery package (preferably installed using biocLite()).

As the documentation states, getGEO() returns a list of ExpressionSet objects when called with GSEMatrix=TRUE. Let me know if that doesn't clarify things. Sean
