secrlinear 1.0.1

New features or changed behaviour of old functions

• read.linearmask will read directly from a polyline shapefile
• interpoint distances within a line are coerced to the correct spacing value (no longer simple Euclidean distances)
• direct and precise algorithm for placing mask points along lines (no longer calls spsample)
• edge editing functions redefined; function showedges() replaces showskips()
• make.line() enhanced (randomstart, endbuffer, clusters, multiline masks etc.)
• new function cleanskips() removes superfluous joins (automatic in read.linearmask)

Bugs fixed

• none yet

Other

• now 'Depends' on igraph package (always loaded)
• no longer exports alongmask() (use make.line())
