This is a very specialised question, and even on the more appropriate list
R-sig-geo might not be answered. Writing to the package maintainer is one
possibility, but as you see from:

library(McSpatial)
example(qregspiv)
fit <- qregspiv(form, wmat=wmat, data=mdata, rhomat=seq(-1,1,0.01),
nboot=300, tau=0.5)
str(fit)

shows only:

 num [1:4, 1:4] 7.35 0.288 0.343 0.05 1.993 ...
 - attr(*, "dimnames")=List of 2
  ..$ : chr [1:4] "(Intercept)" "lnland" "lnbldg" "WY"
  ..$ : chr [1:4] "Coef." "Std. Err." "Z-Values" "Pr(>|z|)"

so that apart from the coefficient values and their distribution summaries,
nothing else is returned. This means that you will have to put qregspiv into
debug() mode, and manipulate those internal objects that you need, but which
are not returned.

Hope this helps,

Roger
