[R] pass character vector in instrument field of get.hist.quote function

[algotr8der]

Thanks David for the reply. I just tried the following with the same result:

>library(tseries)
>tickers <- read.csv("testticker.txt", header=FALSE, sep=",")
>tickers <- tickers[1]
     V1
1   XOM
2   COP
3 PBR-A
4  FFIV
5    SU
6 PBR-B


> tickers$V1 <- as.character(tickers$V1) 
> tickers$V1
[1] "XOM"   "COP"   "PBR-A" "FFIV"  "SU"    "PBR-B"

> symbols <- tickers$V1
> symbols
[1] "XOM"   "COP"   "PBR-A" "FFIV"  "SU"    "PBR-B"

> stockdata <- data.frame()
> stockdata <- coredata(get.hist.quote(instruments=symbols,
> start="2011-01-01", end="2011-01-31", quote=c("Close"), provider="yahoo"))
Error in get.hist.quote(instruments = symbols, start = "2011-01-01", end =
"2011-01-31",  : 
  unused argument(s) (instruments = symbols)
