blotter updatePortf issue..

FYI, R-Forge has built Rev. 1151.  So, you should be able to install with

    install.packages("blotter", repos="http://R-Forge.R-project.org")

If you are able to checkout the code using an svn client, but can't
figure out how to build it, you can probably install it with something
similar to this:

    install.packages("/path/to/svn/blotter/pkg/blotter/", repos=NULL,
type='source')

You want to see

    > packageVersion("blotter")

    [1] ?0.8.11?

Good luck,
Garrett

Hi Garrett,
Thank you for both the fix as well as for your guidance. I will go
through the links and try to build the latest version and try again
along with the changes suggested.

Regarding warning messages (while downloading data from Yahoo), I have
been getting these messages right from the time I started using R
(including on demo code). So I just assumed it was a harmless message
everyone gets. I will check it out.

Regards,
Pie

Hi Pie,

Thanks for providing reproducible code.  I committed a patch in Rev.
1151 that I believe will fix your problem.  If you need help checking
out and building the latest revision, see this post on SO:
http://stackoverflow.com/a/11105132/967840

Internally, the code was checking to see if "Dates" was timeBased.  If
it wasn't, it was being converted to a timeBased vector.  But, later,
the code was treating "Dates" as if it were not timeBased.  Hopefully
my patch fixes your problem and doesn't create others.

There are a couple other things to mention.  First, these lines are
not going to work:

    updateAcct(account, Dates=paste('::',as.Date(Sys.time()),sep=''))
    updateEndEq(account, Dates=paste('::',as.Date(Sys.time()),sep=''))

These functions do not support that type of "Dates" strings.  You'll
have to either use Dates=NULL, or supply both starting and ending
dates like this:

    updateAcct(account, Dates=paste(initDate, as.Date(Sys.time()),sep='::') )
    updateEndEq(account, Dates=paste(initDate, as.Date(Sys.time()),sep='::') )


Second, I didn't get these warnings that you got

getSymbols(symbols, src='yahoo',

index.class=c("POSIXt","POSIXct"),from='2001-01-01')
[1] "QQQ" "IWM"
Warning messages:
1: In download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m,  :
  downloaded length 147933 != reported length 200
2: In download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m,  :
  downloaded length 147996 != reported length 200

I'm not sure why you get those warnings, but your version of quantmod
is a little older than mine (the R-forge version).

HTH,
Garrett

Hi,
Currently I am stuck on an error with updatePortf function in blotter. The
error message is same as the issue mentioned on R-sig-finance previously
