Nrows | R Documentation |
This function loads and runs the compiled fortran code cnvrt. cnvrt is Piepel's 1988 JQT fortran code for extreme vertices designs.
Nrows(ndm,nvrr,ncon2,rtheta2)
ndm |
This is the order of centroids desired (0=none, 1=edge centroids, 2=face centroids etc.) |
nvrr |
This is the number of mixture variables ( maximum is 12) |
ncon2 |
This is the number of constraints (maximum is 45) |
rtheta2 |
This is the constraint matrix stored as a vector of columns. |
nvrtr
nvrtr |
This is the number of rows in rxvt the matrix of extreme vertices and centroids |
This function is called by the function crtave.
