Re: [R-SIG-Finance] object .blotter not found
My guess is that either you used a clear workspace button on your
GUI, or you did something to the effect of rm(list=ls(all=TRUE)).
.blotter is an environment that is stored under your .GlobalEnv when
you load the package. If you delete it, you have to put it back with
something like this
if (!exists('.blotter')) .blotter - new.env()
Prior to 2012, the .instrument environment was also stored in the
.GlobalEnv, but with FinancialInstrument version 0.10.0, it was moved
to live in the top level of the package. Therefore, the .instrument
environment doesn't get wiped out if the user clears their workspace.
But, it appears to be missing unless you know where to look.
This should work
ls(FinancialInstrument:::.instrument)
But, it's not as robust as using
ls_instruments()
.blotter should probably be moved out of the .GlobalEnv as well, but
for now, either don't clear your .GlobalEnv, or recreate a .blotter
environment after you do.
HTH,

Hi Garrett
Yes your guess is good and solution works. Also just found upon the
getAnywhere() function, which can find hidden objects. Thanks very much.
