A common way to do this is to store your data in its own environment.
Then,
use eapply to get a list of close prices. Finally, construct a merge call
with do.call
s - c(SPY, AAPL)
myEnv - new.env()
getSymbols(s, src='yahoo', env=myEnv)
p - do.call(merge, eapply(myEnv, Cl))
this is like calling merge(Cl(SPY), Cl(AAPL)), but it will work for any
number
of symbols.
Similarly, if your data are stored in your globalenv(), you can create a
list
of Close prices and merge them together using do.call.
s - c(SPY, AAPL)
getSymbols(s, src=yahoo)
p - do.call(merge, lapply(s, function(x) Cl(get(x, pos=globalenv()
I also happen to have a function that does this for you in one line in my
qmao
package on R-Forge. https://r-forge.r-project.org/R/?group_id=1113
library(qmao)
p - PF(getSymbols(c(SPY, AAPL)), silent=TRUE)
HTH,
Garrett

Hi,
1) When I call getSymbols with multiple symbols, is there any way I can
obtain everything into one xts. Says, I want only close data from google
for c(SPY,AAPL). Is there anyway I can get an xts with 2 columns
corresponding to SPY and AAPL close prices?
2) Similar to #1, if I have all symbols loaded from files (.RData), is
there any better way to combiing them than merging them one-by-one using
xts?
Thank you.
Robert
