[R-SIG-Finance] Question in blotter::updatePosPL file: argument is of length zero

[Lei Jin]

In the file updatePosPL.R, line 35 is

if(ncol(Prices)>1) Prices=getPrice(Prices,Symbol)

However, if the Prices() is NULL (which is by the default parameter to
this function), then ncol(Prices) is also NULL, and
this will cause the error below.

Should line 35 checks the prices, not Prices?

==================================================
debug: if (ncol(Prices) > 1) Prices = getPrice(Prices, Symbol)
Browse[2]> print(Prices)
NULL
Browse[2]> print(ncol(Prices))
NULL
Browse[2]> n
