I stand corrected. It is possible for the S4 cbind to know the symbol of
unnamed arguments, by "cheating": colnames(base::cbind(...,deparse.level =
deparse.level)) -- which tells me that there ought to be a non-cheating way.
I note that the Rmpfr class union, Mnumber, means that the simple cbind(1
I truly am grateful for all the help.
I never would have thought defining a class union for objects that can be
combined with cbind, as you do in Rmpfr. That does the trick.
Is it true that the only difference in behavior between the S4 cbind and
base::cbind is that, unlike base::cbind, the S4 cb
To be more precise, while the build process worked, the check did not. When
it got to the point "* checking for portable compilation flags in Makevars
..."
a number of shells popped up (to run c:\Rtools\sh.exe) and the process died.

Hello,
After much tinkering I managed to build packages using the 64bit version of
R with the help of hints from
http://www.murdoch-sutherland.com/Rtools/
and
http://www.stats.ox.ac.uk/~ripley/Win64/W64porting.html
and
R-admin Manual.
But a hack was required, and this seems to be related to
a com

v2.11.0 there is now an arrayInd() in the 'base' package doing exactly
the same thing. See help(arrayInd).

For what it's worth, see arrayIndex() in R.utils, e.g.
# Single index
print(arrayIndex(21, dim=c(4,3,3)))
# Multiple indices
print(arrayIndex(20:23, dim=c(4,3,3)))
# Whole array
x <- array(1:30, dim=c(5,6))
print(arrayIndex(1:length(x), dim=dim(x)))
# Find (row,column) of maximum value
