plotMap.CSV: Plots a dataframe or csv file on a map using GMT.

In wStockhausen/wtsGMT: Functions for creating maps with GMT 4.5 (and maybe 5.1)

Description

A function to plot a dataframe or csv file on a map using GMT.

Usage

plotMap.CSV(dfr = NULL, lat = "latitude", lon = "longitude", col = NULL,
  gmt = 4, title = "Tanner Crab", year = "", xyrng = "180/205/54/62",
  zscl = NULL, zlab = "Catch", zunits = "num. crab", rotate = FALSE,
  elev = 70, delx = 0.5, dely = 0.25, blocktype = c("MEAN", "SUM"),
  plt_blocktype = c("SMOOTH", "COARSE"), logtr = FALSE, plt_title = FALSE,
  plt_bars = FALSE, plt_surface = FALSE, plt_blocklocations = FALSE,
  plt_colorscale = plt_surface | plt_bars, plt_stations = FALSE,
  plt_reflines = FALSE, reflines = list(list(lon = -166 + 0 * seq(from = 50,
  to = 80, by = 1), lat = seq(from = 50, to = 80, by = 1))),
  psFile = "catchMaps", toPDF = FALSE, bathymetryFile = file.path(getwd(),
  "data/depthcontour_200500.prn"), cleanup = FALSE)

Arguments

dfr	= dataframe or csv file to plot
lat	= column name containing latitudes
lon	= column name containing longitudes
col	= name of column containing z data
gmt	= GMT version (4 or 5)
title	= map title
year	= year label
xyrng	= x-y range for map as GMT string ('xmin/xmax/ymin/ymax')
zscl	= z-scale (max) for map
zlab	= label for z axes
zunits	= units for z axes
rotate	= flag (T/F) or value of angle for map rotation (angle=180 if rotate=T/F)
elev	= elevation for map perspective is rotate is not FALSE
delx	= x increment for associated grids
dely	= y increment for associated grids
blocktype	= flag ('MEAN' or 'SUM') for grouping data
plt_blocktype	= flag ('SMOOTH','COARSE') for displaying surface
logtr	= flag to ln-transform z data
plt_title	= flag to include title on map
plt_bars	= flag to plot data as bars
plt_surface	= flag to plot data as a color density image
plt_blocklocations	= flag to plot block locations as X's
plt_colorscale	= flag to plot color scale
plt_reflines	= flag to include refernce lines on map
reflines	= list of lists(lon=,lat=) of reference lines to plot
psFile	= filename for output file (no extension–will be pdf)
cleanup	= flag to remove temporary files
pdfDir	= directory for output file
bathymetryfile	= filename of bathymetry to plot

Details

External Requirements: * GMT 4.5.x * on Windows, need both gswin32c and gswin64c installed * on network, need to use mapped drives to specify files
Z-values > zscl are truncated to zscl so they will plot (otherwise GMT removes them completely, apparently)

Value

z-scale used for plot.
