airdist

<p>annotate the plot with line measured and distance</p>

<p>Measure a distance between two points on a plot using <code>locator</code>; the function checks <code>par("plt")</code> and <code>par("usr")</code> to try to ensure that the aspect ratio y/x is 1, that is that the units of measurement in both x and y are equivalent.</p>

spatial

A collection of functions to create spatial weights matrix
objects from polygon 'contiguities', from point patterns by distance and
tessellations, for summarizing these objects, and for permitting their
use in spatial data analysis, including regional aggregation by minimum
spanning tree; a collection of tests for spatial 'autocorrelation',
including global 'Morans I' and 'Gearys C' proposed by 'Cliff' and 'Ord'
(1973, ISBN: 0850860369) and (1981, ISBN: 0850860814), 'Hubert/Mantel'

'spdep' >= 1.1-1 corresponds to 'spatialreg' >= 1.1-1, in which the model
fitting functions are deprecated and pass through to 'spatialreg', but
will mask those in 'spatialreg'. From versions 1.2-1, the functions will
be made defunct in 'spdep'.
For now 'spatialreg' only has functions from 'spdep', where they are shown
as deprecated. 'spatialreg' only loads the namespace of 'spdep'; if you
attach 'spdep', the same functions in the other package will be masked.
Some feed through adequately, others do not.
