Why are my coefficients getting appended with a 1? It borks a match I

The linearModel function that is easiest to find appears (on the basis
of its help page anyway) to be designed as a dialog control function
rather than to be used in the manner you are illustrating. Of course I
could be wrong about which package you are using, and the the
appropriate use of linearModel, but why not see if you don't get more
expected results with:
lm(formula = modelSource ~ +UNITBUILD + UNITDB + ITBUILD + ITDB +
UATBUILD + UATDB + HOGANCODE + RCF + ReleaseST1 + ReleaseST2 +
ReleaseBLA + Small.Bank.Acquisitions + HLY.NewYear + HLY.MLK +
HLY.PRES + HLY.MEMORIAL + HLY.J4 + HLY.LABOR + HLY.COLUMBUS +
HLY.VETS + HLY.THANKS + HLY.XMAS + HLY.ELECT + HLY.PATRIOT +
EOM,
data = mcReg)
Call:
lm(formula = modelSource ~ +UNITBUILD + UNITDB + ITBUILD + ITDB +
UATBUILD + UATDB + HOGANCODE + RCF + ReleaseST1 + ReleaseST2 +
ReleaseBLA + Small.Bank.Acquisitions + HLY.NewYear + HLY.MLK +
HLY.PRES + HLY.MEMORIAL + HLY.J4 + HLY.LABOR + HLY.COLUMBUS +
HLY.VETS + HLY.THANKS + HLY.XMAS + HLY.ELECT + HLY.PATRIOT + EOM,

Now all the variables with a 1 appended are factors so is that normal
behavior? (if so then I can adjust the match() command to pad a 1 to
the master list.)
