WANN objects encapsulating points/kd trees allowing repeated searches
Source:R/WANNClass.R
WANN-class.RdMethods for WANN objects include
build_treedelete_treegetPointsquerySelf
Details
WANN objects will primarily be useful if you make repeated queries. You can also delay building the k-d tree if you are not sure if the object in question will be searched; the tree will automatically be built when it is queried. You can also explicitly control when the tree is built or deleted (for memory management). The tree is wrapped in an R reference class (R5) object which imposes a significant performance penalty for building small trees (< ~ 1000 points). Summarising, WANN objects provide experimental functionality to:
keep ANN points in memory to avoid repeated copying
keep the ANN k-d tree in memory to avoid repeated building
separate building the k-d tree from allocating the points
permit very fast self queries
permit queries of the points from one ANN tree against a second tree
Examples
p1=kcpoints[[1]]
w1=WANN(p1)
# 2 neighbours since the first neighbour will be a self match of each point
k <- 2
# Find the exact nearest neighbors
epsilon <- 0.0
w1sq=w1$querySelf(k, epsilon)
