These functions get or set options for creation of new ‘ExperimentHub’ instances.
The character(1) hub options to set. see ‘Details’ for current options.
The value to be assigned to the hub option.
Supported options include:
character(1). The base URL of the ExperimentHub. Default: https://experimenthub.bioconductor.org
character(1). The location of the hub cache. Default: “.ExperimentHub” in the user home directory.
numeric(1). The integer number of downloads allowed before triggering an error. This is to help avoid accidental download of a large number of ExperimentHub members.
request object returned by
request object describes a proxy
connection allowing Internet access, usually through a restrictive
firewall. Setting this option sends all ExperimentHub requests through
the proxy. Default: NULL.
value can be one of NULL,
request object returned by
httr::use_proxy(), or a
well-formed URL as character(1). The URL can be completely
username:password and port (e.g.
:8080) are optional.
logical(1). Should the ExperimentHub create a hub consisting only of previously downloaded resources. Default: FALSE.
logical(1). TRUE/FALSE should the ExperimentHub ask if the hub location should be created. If FALSE, the default location will be used and created if it doesn't exist without asking. If TRUE will ask the user and if in a non interactive session utilize a temporary directoy for the caching. Default: TRUE.
Default values may also be determined by system and global R
environment variables visible before the package is loaded. Use
options or variables preceded by “EXPERIMENT_HUB_”, e.g.,
options(EXPERIMENT_HUB_MAX_DOWNLOADS=10) prior to package load
sets the default number of downloads to 10.
The requested or successfully set option.
