# One more question, Joshua: let instead of merging tickers

ticker.list <- c('SPY', 'TLT', 'GLD')
getSymbols(ticker.list, env = data)
X <- do.call(to.weekly, list(data))
I think you need do.call(rbind, as.list(eapply(data, function(x) Cl(to.weekly(x)))))
My apologies: that should be rbind()
Damnit.... cbind() Michael
Also, you might want to re-attach names: names(X) <- ticker.list Best, Michael
Working from the inside out: to.weekly -- go to weekly frequency Cl -- take the close eapply -- do this to each element of the data environment as.list -- convert to list do.call(cbind, ...) -- put them all together. Though there may be something simpler. Best, Michael
