Details

A helper function to translate a file path on a LabKey web server to a path accessible by a remote machine. For example, if an R script is run on an R server that is a different machine than the LabKey server and that script references data files on the LabKey server, a remote path needs to be created to correctly reference these files. The local and remote roots of the data pipeline are included by LabKey in the prolog of an R View report script. Note that the data pipeline root references are only included if an administrator has enabled the Rserve Reports experimental feature on the LabKey server. If the remoteRoot is empty or the fullPath does not contain the localRoot then the fullPath is returned without its root being changed.

Examples

# library(Rlabkey)

labkey.pipeline.root <- "c:/data/fcs"
labkey.remote.pipeline.root <- "/volumes/fcs"
fcsFile <- "c:/data/fcs/runA/aaa.fcs"

# returns "/volumes/fcs/runA/aaa.fcs
labkey.makeRemotePath(
	localRoot=labkey.pipeline.root,
	remoteRoot=labkey.remote.pipeline.root,
	fullPath=fcsFile);
