cons.angular.dat {BMAmevt} | R Documentation |
Builds an angular data set, retaining the points with largest radial component.
cons.angular.dat(coordinates = c(1, 2, 3), frechetDat = get("frechetdat"), n = 100, displ = TRUE, invisible = TRUE, add = FALSE, lab1 = "w1", lab2 = "w2", lab3 = "w3", npoints = 60, col.polygon = "white", ...)
coordinates |
Index vector of the columns in |
frechetDat |
The data set. A matrix: each row is a multivariate record. May contain NA's. |
n |
The number of desired observations in the final angular data set. Should be less than |
displ |
logical. Should the angular data set be plotted ? |
invisible |
logical. Should the result be returned as invisible ? |
add |
logical. Only used when |
lab1 |
Character string: label for first component. |
lab2 |
Character string: label for second component. |
lab3 |
Character string: label for third component. |
npoints |
The number of grid nodes on the squared grid containing the desired triangle. |
col.polygon |
The background color outside the simplex. |
... |
Additional graphical parameters and arguments to be passed to function |
The data set frechetDat
is assumed to be marginally unit Frechet distributed.
The angular data set: A n*length(coordinates)
matrix, containing values between zero and one, which rows sum to one: Each row is thus a point on the unit simplex of dimension length(coordinates)-1
. Returned as invisible if invisible==TRUE
.
