After downloading the RNA-seq Metadata of breast cancer with the gdcRNAtools package in R, I ran across this error message while processing and filtering RNA-seq Metadata:
Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") : InternetOpenUrl failed: 'The server name or address could not be resolved.'
I encounter with this problem when i use this code (metaMatrix.RNA - gdcParseMetadata(project.id = 'TCGA-BRCA, data.type = 'RNAseq, write.meta = FALSE):
My internet connection is working correctly, and my device is disconnected from the VPN, and I followed all the protocols in the Bioconductor site perfectly ( http://bioconductor.org/packages/devel/bioc/vignettes/GDCRNATools/inst/doc/GDCRNATools.html ).
How can I resolve this issue?
Yurii Moskalenko The syntax I've provided here is incorrect, but I typed it correctly in the R console. Thank you for your input.
Pejman Morovat Because I know you live in Iran and using an Iranian server, I recommend that use a server from another country. Using a VPN could help you resolve internet connection issue in your R console window.
