Connection can hold a lot of data in cache. If a lot of work has been done (e.g: lots of downloaded datasets and gene-expression matrices), it can be useful to save the connection for later work or even offline use.
loadConnection(file)
saveConnection(con, file)The file name to be saved to or loaded from
An ImmuneSpaceConnection. The connection to save to file.
To be loaded later using loadConnection.
An ImmuneSpaceConnection object
