Brian,
I tried demo('longtrend') and the result is:
# Load data with quantmod
print("Loading data")
[1] "Loading data"
currency("USD")
Error in eval.with.vis(expr, envir, enclos) :
could not find function "currency"
In addition: There were 11 warnings (use warnings() to see them)
My problems started, then I tried to add a new transaction:
addTxn(portfolio, "SPY", '2007-01-03', 50, 96.5, -0.05*50)
[1] "2007-01-03 SPY 50 @ 96.5"
Warning messages:
1: In getInstrument(Symbol) :
Instrument SPY not found, please create it first.
I debugged a bit and I found, that getInstrument function fails on this
line:
if (inherits(tmp_instr, "try-error") | !is.instrument(tmp_instr)) {
I suspect, that FinancialInstrument package isn't committed properly.
Currency, stock methods
do not exist in my environment. The version of FI is 0.02, blotter v.0.4
As well, I have noticed, that environment variables are used very heavily.
What is the reason of using
environment variables instead of local variables? For example, in initPortf
method:
if (exists(paste("portfolio", name, sep = "."), envir = .blotter,
inherits = TRUE))
I found it frustrating, when I tried to recreate a portfolio and an account,
but I couldn't.
Thanks,
kafka
