planarMap

Description

a mapping function that uses levelplot to plot data in planar coordinates

Usage

planarMap(
  xyz,
  depths = T,
  pts = NULL,
  colpts = F,
  annot = NULL,
  annot.cex = 2.2,
  scalebar = T,
  projection = "utm20",
  col.regions = T,
  datascale = seq(0, 1, l = 50),
  at = datascale,
  fn = paste("map", trunc(runif(1) * 1e+08), sep = ""),
  loc = tempdir(),
  corners = NULL,
  rez = c(1, 1),
  save = F,
  pt.cex = 0.5,
  pt.pch = 16,
  pt.col = "black",
  colorkey = NULL,
  fill = T,
  log.variable = F,
  interpolation = F,
  add.zeros = F,
  theta = 50,
  rev = F,
  ...
)

Arguments

`xyz`	data to be plotted
`depths`	= undocumented
`pts`	data points to be overlayed on the map
`colpts`	= undocumented
`annot`	= undocumented
`annot.cex`	= undocumented
`scalebar`	= undocumented
`projection`	to be used, see: lookup.projection.params
`col.regions`	= undocumented
`datascale`	for legend that describes the z variable
`at`	= undocumented
`fn`	= undocumented
`loc`	= undocumented
`corners`	2x2 dataframe that specify the corners of the map i.e. corners = data.frame(lon=c(-67.54,-56.5),lat=c(41,47.2))
`rez`	= undocumented
`save`	logical TRUE saves the map as a .png, FALSE prints to screen
`pt.cex`	= undocumented
`pt.pch`	= undocumented
`pt.col`	= undocumented
`colorkey`	= undocumented
`fill`	= undocumented
`log.variable`	= undocumented
`interpolation`	logical, does thin plate spline interpolation of the z variable and plots the result
`add.zeros`	uses zeroInflate() to add zeros where there is no data before the interpolation (assumes zero outside the sampled area)
`theta`	interpolation parameter
`rev`	= undocumented
`...`	= undocumented
