filterTrack

methods for filter and trim tracks based on track length.

filterTrack(trackll,filter=c(min=7,max=Inf))
trimTrack(trackll,trimmer=c(min=1,max=32))
trackLength(trackll)

Arguments

trackll	a list of track lists.
filter	range of possible track lengths to keep
trimmer	range of track lengths allowed in output, otherwise trimmed.

Examples

folder=system.file('extdata','SWR1',package='sojourner')
trackll=createTrackll(folder=folder, input=3)
#> 
#> Reading ParticleTracker file:  SWR1_WT_140mW_image6.csv ...
#> 
#>  mage6 read and processed.
#> 
#> Process complete.

trackll.filter=filterTrack(trackll,filter=c(7,Inf))
#> applying filter, min 7   max Inf 
trackll.trim=trimTrack(trackll,trimmer=c(1,20))
#> applying trimmer, min 1   max 20 

# see the min and max length of the trackll
# trackLength() is a helper function output track length of trackll
