vario.plot {RGeoS} | R Documentation |
Performs the graphic representation of an experimental variogram and a model for one or several directions (usually the ones for which some experimental variograms have been computed), for one or several variables.
vario.plot(x = NA, xlim = NA, ylim = NA, npairdw = FALSE, npairpt = 0, flag.norm = FALSE, flag.vars=TRUE, flag.envelop=TRUE, as.cov=FALSE, norder=0, inches = 0.1, cex = 1, pch = NA, lty = 1, col = NA, lwd = 1, lwd0 = 1, lty0 = 2, pos=3, offset=1, varline = TRUE, xlab = "", ylab = "", nh = 100, varcols=NA, varcols2=NA, maxnvar = 5,idir0=0,add=FALSE,reset=TRUE,...)
x |
The |
xlim |
An array of two values giving the minimum and maximum values along the horizontal axis |
ylim |
An array of two values giving the minimum and maximum values along the vertical axis |
npairdw |
Proportional representation of the number of pairs. Circle areas are proportionnal to the values, i.e radii proportionnal to square root of the values |
npairpt |
Display the number of pairs. If npairdw=FALSE, a constant size circle is indicates the pair location. |
flag.norm |
If TRUE, the variogram is normalized by the variable variance before it is represented |
flag.vars |
1 if the global statistics must be taken into account for calculating graphic extension |
flag.envelop |
if TRUE and if the two variable indices are different, the coregionalization envelop if added to the graphic. |
as.cov |
If TRUE, the structure is represented as a covariance; otherwise it is represented as a variogram. |
norder |
When equal to 0, this corresponds to the standard variogram. When strictly positive, it corresponds to the order of the Generalized Variogram. |
inches |
Size for the representation of the number of pairs |
cex |
Size for the points in when npairdw=FALSE |
pch |
Used when npairdw=FALSE to choose the symbols |
lty |
Type of line for drawing the experimental variogram |
col |
Color of the lines and symbols |
lwd |
Width for the lines |
lwd0 |
Width used for the axes |
lty0 |
Type of the lines used for the axes |
pos |
Position of the labels with respect to the symbol representing the variogram lag (only used when npairpt=TRUE).
|
offset |
When variogram is represented with npairpt=TRUE, this value gives the offset of the label from the symbol representing the variogram lag (in fractions of a character width). |
varline |
Horizontal line at the sample variance/covariance level This option is automatically discarded in case of generalized variograms. |
xlab |
Label given on the horizontal axis |
ylab |
Label given on the vertical axis |
nh |
Number of discretization points |
varcols |
List of the indices of the fields to be represented (along X-axis). If not specified, all the variables from 1 to 'maxnvar' are represented. |
varcols2 |
List of the indices of the fields to be represented (along Y-axis). If not specified, the argument varcols is used instead. |
maxnvar |
Maximum number of figures to be represented. |
idir0 |
Rank of the direction of interest or 0 for all directions |
add |
When FALSE a new page is initialized before the graphic. Otherwise, the graphic is overlayed on the already existing page. |
reset |
When TRUE, the screen is erased before the variogram plot is performed. |
