densityanomaly() added, to highlight differences
between kernel density for individual surveys and mean kernel density
across all surveys
segvert2xy() added, to extract XY coordinates from
vectors of segment and vertex
xy2segvert() and ptshp2segvert() now
include columns snap_x and snap_y,
corresponding to the XY coordinates of each point, “snapped” to the
river network.
plot.riverdensity()riverpoints()sf package.plot.homerange()sp and
rgdal packages, and transition to newer-generation
sf package.cleanup_verts() added, for editing of the vertices
of individual segments
routelist() now returns all complete routes (and
faster)
splitsegments() can now split a subset of segments
at specified locations
connectsegs() can now connect vectors of
segments
cleanup() improved
Better algorithm used for checkbraidedTF() - MUCH
faster, and no longer hangs in a complex test case
detectroute(..., algorithm="Dijkstra") speeded up
substantially
topologydots() speeded up
Better algorithm used for checkbraidedTF() - MUCH
faster, and no longer hangs in a complex test case
plot.rivernetwork() no longer errors when only one
segment is visible in plotting window
homerange() now creates homerange-class
objects
Added plot.homerange(),
homerangeoverlap() and plothomerangeoverlap(),
which all accept homerange-class objects
Optimization in homerange(): speeded up by a factor
of 10ish, depending on the dataset
Line color in an empty plot with plot.rivernetwork()
now settable with argument linecol=
mouthdist() accepts vectors of segment and vertex
coordinates
segmentnum= and empty= in
plot.rivernetwork() and others re-implemented
plot.riverdensity() with
scalebar=Tplot.riverdensity() in the correct
order, if survey is a factor variable with levels in a
different order than alphabeticMaking an empty river plot (using
empty=TRUE)
Jittering riverpoints() using jitter
argument
Optimization in riverpoints() and
xy2segvert(): both were speeded up by a factor of
10
Optimization in plot.rivernetwork(): speeded up by a
factor of 2

was identified and fixed.Distance calculation is much, much faster since the last CRAN release (0.11.0). Both the Dijkstra and segroutes algorithm run in about one hundredth the time that they previously did.
Additional components were added to the rivernetwork class, to
aid in distance calculation speed. $cumuldist is a list of
vectors of cumulative distances associated with each line segment, and
$distlookup is a list of lookup tables. Distance
calculation is now done using these components, which will need to be
calculated for any saved river network objects.
Bugs in the dissolve() and homerange()
functions and segroutes algorithm were identified and fixed.
New connection types were added, to handle special cases in braided networks.
Error handling in line2network() was improved, and
more complex networks can now be read in a manageable amount of
time.
