correlation {RGeostats}  R Documentation 
Plot the translated correlation, for one or two variables
correlation(db, name1=1, name2=NA, db2=NA, name.size=NA, ndisc=100,flag.plot=TRUE, flag.same=TRUE, flag.regr=FALSE, flag.iso=FALSE,flag.diag=FALSE,flag.aspoint=FALSE,dmin=NA,dmax=NA, dirvect = NA, tolang = NA, opt.code = 0, tolcode = 0, mini1=NA, maxi1=NA, mini2=NA, maxi2=NA, lin.lty=1, lin.lwd=1, lin.col= "black", xlab=NA, ylab=NA, title=NA, verbose=FALSE,...)
db 
The 
name1 
Rank of the column containing the first target variable 
name2 
Rank of the column containing the second target variable 
db2 
If 'db2' is specified, the second variable is read from this Db. This option is only available when flag.same=TRUE. This Db2 must have exactly the same organization as 'Db'. 
name.size 
When the argument 'flag.aspoint' has been switched ON, the samples
are represented as circles. If the argument 'name.size' is defined
(as a valid attribute of 
ndisc 
Number of discretization steps along each axis for graphic representation 
flag.plot 
TRUE if the correlation plot is produced. 
flag.same 
TRUE if the variables must be compared at the same location (standard correlation). FALSE for the shifted correlation 
flag.regr 
When TRUE, represent the regression line of the variable 'name2' as a function of the variable 'name1' 
flag.iso 
When TRUE, the axes are the same, calculated from the minimum of both variables to the maximum of both variables. 
flag.diag 
When TRUE, represent the diagonal between the lower left and the upper right corners 
flag.aspoint 
When TRUE, the different symbols are represented as circles (of constant or varying radii). When FALSE, the samples are migrated onto an internal fine grid. Then the density of samples per grid node is displayed using a colored raster representation of this internal grid. 
dmin 
Minimum distance for the calculation of the translated correlation 
dmax 
Maximum distance for the calculation of the translated correlation 
dirvect 
The directions in which the translated correlation must be calculated.
For more information, refer to 
tolang 
Angular tolerance. If no angular tolerance is not defined, the tolerance is set to 90 degrees. 
opt.code 
Option concerning the sample codes for constituting pairs:

tolcode 
Maximum distance between the codes of the two samples. 
lin.lty 
Type of the line used to represent the linear regression and/or the bissector. 
lin.lwd 
Thickness of the line used to represent the linear regression and/or the bissector. 
lin.col 
Color of the line used to represent the linear regression and/or the bissector. 
mini1 
Minimum value for the first target variable 
maxi1 
Maximum value for the first target variable 
mini2 
Minimum value for the second target variable 
maxi2 
Maximum value for the second target variable 
xlab,ylab 
Labels for the graphic, arguments used by the Splus function "plot" 
title 
Title to be displayed (optional) 
verbose 
When TRUE, the calculation of the correlation and (optionally) the regression line produces verbose outputs. 
... 
When one variable is provided, the function calculates: Correl(Z1(x),Z1(x+h)) For two variables, the function calculates: Correl(Z1(x),Z2(x+h))
The correlation coefficient.
