In geo: Draw and Annotate Maps, Especially Charts of the North Atlantic

Description

Plots lines of equal depths using a database from GEBCO.

Usage

gbplot(depth, col, lty, lwd, depthlab, depthlabcex)

Arguments

depth	A vector of the depths which we want equidept lines plotted.
col	The colour of the lines, if the col vector is shorter than the depth vector it is repeated. Default is all lines black.
lty	Linetype, if the lty vector is shorter than the depth vector it is repeated. Default is all lines have linetype 1.
lwd	Linewidth, if the lwd vector is shorter than the depth vector it is repeated. Default is all lines have linewidth 1.
depthlab	A boolean variable determening whether labels should be printed on equidepth lines, default is false.
depthlabcex	The size of depthlabels.

Value

None

Examples

   geoplot()   # Set up plot.
   
   gbplot(c(100,500,1000),depthlab=T,depthlabcex=0.2)
   # Plot depthlines for 100,500,1000,1500 m, showing the
   # depth on the line.
