Simple portfolio management - anything in R?

every time I start looking at those things I glaze over...

I recommend a double espresso.  Then:

library(blotter)
?blotter

In the example provided, you can see your starting point:
?getSymbols
?initPortf
?addTxns
?updatePortf
?initAcct
?updateAcct
?updateEndEq

Peter,
   Thanks for the pointers. I've made a little bit of headway this
Friday afternoon and likely can make more progress over the weekend.

   One quick question, mostly out of curiosity. How/where are blotter
portfolios stored? The initPortf function seems to create something
lasts beyond my current run of R. If I exit R-Studio, reenter and
rerun my code that created the portfolio in the first place it tells
me:

initPortf(name="Mark1",symbols="StockList")

Error in initPortf(name = "Mark1", symbols = "StockList") :
  Portfolio Mark1 already exists, use updatePortf() or addPortfInstr()
to update it.

I do see it's in the blotter environment:

ls(envir=.blotter)

[1] "portfolio.Mark1"

   I'm on Linux, ran updatedb and attempted to locate both portfolio
and Mark1 but didn't find anything meaningful.

Thanks,
Mark
