lineartileindex  R Documentation 
Given a tessellation on a linear network, and a list of points on the network, determine which tile of the tessellation contains each of the given points.
lineartileindex(seg, tp, Z, method = c("encode", "C", "interpreted"))
seg,tp 
Vectors of local coordinates of the query points. See Details. 
Z 
A tessellation on a linear network (object of class

method 
Internal use only. 
This lowlevel function is
the analogue of tileindex
for linear networks.
For a tessellation Z
on a linear network,
and a list of query points on the same network,
the function determines which tile of the tessellation
contains each query point.
Argument Z
should be a tessellation on a linear network
(object of class "lintess"
).
The vectors seg
and tp
specify the locations
of the query points, on the same network, using local coordinates:
seg
contains integer values specifying which
segment of the network contains each query point;
tp
contains numeric values between 0 and 1 specifying the
fractional position along that segment.
The result is a factor, of the same length as seg
and tp
,
indicating which tile contains each point. The levels of the factor
are the names of the tiles of Z
.
A factor, of the same length as seg
and tp
,
whose levels are the names of the tiles of Z
.
lintess
.
as.linfun.lintess
to create a function whose
value is the tile index.
cut.lpp
for a neater way to classify
the points of a point pattern on a linear network
according to a tessellation on the network.
