Changes current working directory in Genomic Database.
gdir.cd(dir = NULL)
None.
This function changes the current working directory in Genomic Database (not to be confused with shell's current working directory). The list of database objects - tracks, intervals, track variables - is rescanned recursively under 'dir'. Object names are updated with the respect to the new current working directory. Example: a track named 'subdir.dense' will be referred as 'dense' once current working directory is set to 'subdir'. All virtual tracks are removed.
gdb.init_examples()
gdir.cd("subdir")
gtrack.ls()
#> [1] "dense_track2"
gdir.cd("..")
gtrack.ls()
#> [1] "array_track" "dense_track" "rects_track"
#> [4] "sparse_track" "subdir.dense_track2"
