[R-SIG-Finance] What are the requirements for instrument names in a blotter portfolio?

[Robert Nicholson]

Why when

names(getPortfolio(portfolio))
  [1] " -24702R9GE"

do I have

[1] "2008-05-30  -24702R9GE 10 @ 35"
Error in get(x, pos = .instrument) : object ' -24702R9GE' not found
Error in get(Symbol, envir = as.environment(.GlobalEnv)) : 
  object ' -24702R9GE' not found

when I call

	portfolio = updatePortf(Portfolio = portfolio, Dates = CurrentDate)
