Display 2-D surfaces along traces
db.section.plot(x, dbgrid, dbpoint = NA, addnames = NA, disc = 1, radius = 1, cols = NA, flag.fill = TRUE, flag.revert = FALSE, flag.up = TRUE, flag.z = TRUE, flag.vertex = TRUE, flag.text=FALSE, iatt.point=NA, fg.col = "black", col0 = "black", pos0=1, lwd0 = 1, lty0 = 1, title = NA, pos.legend=0, add = FALSE, reset = TRUE, ...)
x |
The trace defined as a matrix with 2 columns (for first two coordinates) and as many rows as vertices. |
dbgrid |
The |
dbpoint |
An auxiliary |
addnames |
A set of variables (defined by their attribute ranks) which define additional surfaces to be overlaid. |
disc |
Discretization step used for interpolating the different surfaces. |
radius |
Radius of the search distance used for selecting the samples (contained in 'dbpoint') to be represented. A sample is represented only if its distance to an trace interpolated point is smaller than this argument. The sample is attached to the closest trace interpolated point. |
cols |
List of colors used for representing the surfaces. |
flag.fill |
When TRUE, a polygon joining the interpolated surface (along the trace) to the two bottom edge corners of the section is represented. When FALSE, the surface is represented as a broken line. |
flag.revert |
When TRUE, the surfaces are represented starting from the one corresponding to "z1" (resp. "time1") upwards. When FALSE, the surfaces are represented ordered downwards. |
flag.up |
The vertical axis is represented upwards when the argument is TRUE and downwards otherwise. |
flag.z |
When TRUE, the variables of 'dbgrid' which correspond to the "z" locator are displayed. When FALSE, the variables corresponding to the "time" locator are represented instead. |
flag.vertex |
When TRUE, the vertices of thandare displayed (as vertical solid lines) |
flag.text |
When TRUE, display the label next to the samples located close enough to the trace. |
iatt.point |
This gives the attribute containing the literal value to be displayed (only used if 'flag.text' is TRUE) |
fg.col |
(Foreground) color used for representing the samples from 'dbpoint'. |
col0 |
Array of colors used for representing the additional surfaces from 'dbgrid'. |
pos0 |
Position of the label with respect to the location of the sample located close enough to the trace. |
lwd0 |
Array of line widths for representing the additional surfaces from 'dbgrid'. |
lty0 |
Array of line types for representing the additional surfaces from 'dbgrid'. |
title |
A character string representing the title. |
pos.legend |
Position of the legend. For more information, see |
add |
TRUE to overlay on the previous contents of graphic; FALSE otherwise |
reset |
When TRUE, the screen is erased before the plot is performed. |
