Local database connection and remote download error using curatedTCGAData

Question

[robjohn70000]

Hi,

I'm experiencing issues with curatedTCGAData for remote data downloading and local database connection. As a note, I work behind a firewall.

1. Commands for remote downloading:

   setExperimentHubOption("PROXY", "http://my.proxy:8080") proxy = getExperimentHubOption("PROXY") brca <- suppressMessages(curatedTCGAData("BRCA",c("mRNAArray"),FALSE, proxy=proxy))

Output error:

Error: Could not connect to database:
unable to open database file
Error in dbDisconnect(con) : object 'con' not found

1. Command for local data:

   Local experimenthub.sqlite3 download: setExperimentHubOption("CACHE","/path-to-data/experimenthub.sqlite3") cache=getExperimentHubOption("CACHE") brca <- suppressMessages(curatedTCGAData("BRCA",c("mRNAArray"),FALSE, cache=cache))

   Output error:

   Error: Could not connect to database: unable to open database file Error in dbDisconnect(con) : object 'con' not found

Can anyone who is familiar with ExperimentHub package help please? Thanks
