Tools for spatially explicit capture-recapture analysis of animal populations in linear habitats, extending package 'secr'.
Changes in version 1.1.1 (2017-12-13)
Other o avoid change of directory in examples o updated vignette
Changes in version 1.1.0 (2017-05-03)
Other o rgdal::readOGR used to read shapefiles (maptools::readShapexxx deprecated) o compatible secr 3.0.1
Changes in version 1.0.5 (2015-01-11)
Other o CITATION file uses package metadata
Changes in version 1.0.4 (2014-12-08)
New features or changed behaviour of old functions o none yet
Other o editorial changes to help pages o removed dependency on rgeos (still required for clipmask) o replaced NA with zero in input to graph.adjacency
Changes in version 1.0.3 (2014-12-02)
New features or changed behaviour of old functions o read.linearmask() allows for multiple Line objects within each Lines object of a SpatialLinesDataFrame o subset.linearmask() acquires argument droplinesbeyond for cleaning the SLDF attribute o snapPointsToLinearMask() now snaps to the vertices of the graph attribute, rather than trying to use the maptools function snapPointsToLines() o showpath() also returns mask coordinates along each selected path o checkmoves() new utility function for detecting extreme moves o plot.linearmask() now uses plot.mask allowing a wider range of options
Other o first CRAN release o addedge and deleteedge renamed addedges and deleteedges o vignette considers breaks in graph and new secr function 'checkmoves'
Changes in version 1.0.1 (2014-11-02)
New features or changed behaviour of old functions o read.linearmask will read directly from a polyline shapefile o interpoint distances within a line are coerced to the correct spacing value (no longer simple Euclidean distances) o direct and precise algorithm for placing mask points along lines (no longer calls spsample) o edge editing functions redefined; function showedges() replaces showskips() o make.line() enhanced (randomstart, endbuffer, clusters, multiline masks etc.) o new function cleanskips() removes superfluous joins (automatic in read.linearmask)
Bugs fixed o none yet
Other o now 'Depends' on igraph package (always loaded) o no longer exports alongmask() (use make.line())
