extractor.toy {calibrator}  R Documentation 
Extracts lat/long matrix and theta matrix from D2.
Description
Extracts x.star.toy
and t.vec.toy
from D2
; toy
example needed because the extraction differs from case to case.
Usage
extractor.toy(D1)
Arguments
D1 
Matrix of code run points 
Details
The first two columns give the elements of x.star
and columns 3 through 5 give the elements of t.vec
.
Function extractor.toy
is the inverse of function
D1.fun
, in the sense that extractor.toy
splits up
D1
into x.star
and t.vec
, while D1.fun
joins them up again
Value
Returns a list with two elements:
x.star 
A matrix containing the lat/longs of the code run points 
t.vec 
A matrix containing the parameters used for the code runs
