maf.calc {RGeostats}  R Documentation 
Calculate the MAF for a multivariate data set
maf.calc(db, dirvect = NA, h0 = 0, dh = 1, tolang = NA, bench = 0, cylrad = 0, opt.code = 0, tolcode = 0, verbose = FALSE)
db 
The 
dirvect 
The directions in which the variogram must be calculated.
For more information, refer to 
h0 
The smallest distance between pairs of samples retained for the calculation of the MAFs. 
dh 
The largest distance between pairs of samples retained for the calculation of the MAFs. 
tolang 
Angular tolerance for the calculation direction. 
bench 
Bench separation tolerance for the calculation direction. When bench is defined and positive, a pair is discarded if the separation distance between the two points along the third axis is larger than 'bench'. 
cylrad 
Cylrad tolerance for each calculation direction. When specified and positive, a pair is discarded if the separation distance in the plane orthogonal to the calculation distance is larger than 'cylrad'. 
opt.code 
Option concerning the sample codes for constituting pairs:

tolcode 
Maximum distance between the codes of the two samples. 
verbose 
When TRUE, the verbose option is switched ON during the calculation of the MAFs. 
A pcaclass
object which contains the transformation
matrices from Variables to Factors and viceversa.
