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

[Robert Nicholson]

Why then do I get this?

I added

Transactions$Symbol = sub('[ -]*','INST',Transactions$Symbol)

so this prefixes everything I had with INST presumably I can have digits in the name

1] "2008-05-30 INST24702R9GE 10 @ 0.35"
Error in get(x, pos = .instrument) : object 'INST24702R9GE' not found
Error in get(Symbol, envir = as.environment(.GlobalEnv)) : 
  object 'INST24702R9GE' not found
