tries to find a channel in a flowSet/flowFrame that could be the time channel. First tries to identify a channel name containing the 'time' string, then tries to identify a single monotonically increasing channel.
findTimeChannel(obj, excludeChannels = c())
a flowCore::flowFrame or flowCore::flowSet
vector of column names to exclude in the search
a character, name of the found channel that should be representing time. If not found, returns NULL.
data(OMIP021Samples)
ret <- findTimeChannel(OMIP021Samples[[1]])
ret # "Time"
#> [1] "Time"
