What nonsense. There is a group of finger-waggers on this list who jump on
every poster who uses the name of an R function as a variable name. R is
perfectly capable of distinguishing the two, so if 'c' (or 'data' or 'df',
etc.) is the natural name for a variable then go ahead and use it.
Is it really that complicated? This looks like an ordinary quadratic
programming problem, and 'solve.QP' from the 'quadprog' package seems to solve
it without user-specified starting values:
library(quadprog)
Dmat - t(C) %*% C
dvec - (t(C) %*% d)
Amat - -1 * t(A)
bvec - -1 * b
rslt -
I agree that 'list' is a terrible package name, but only secondarily
because it is a data type. The primary problem is that it is so generic
as to be almost totally uninformative about what the package does.
For some reason package writers seem to prefer maximally uninformative
names for

The following approach works for both of your examples:
xx - rep(x, length.out=n)
xx[m:n] - NA
Thus:
n - 2
aa - rep(a, length.out=n)
aa[(length(a)+1):n] - NA
aa
[1] 2008-01-01 NA
bb - rep(b, length.out=n)
bb[(length(b)+1):n] - NA
bb
[1] aNA
Levels: a

I think this was posted to the wrong list, so my followup is going to
R-devel.
