Hi all:
I have a directory of files as in -------------> bunchafiles <-
list.files(path="/data/2.3/2006", pattern="returns",
full.names=T,recursive=T) .... Each file is a bunch of returns for a
particular date (unique). There are like 252 files or so.
With a custom function myread (below), I define a vector ----- res <-
vector("list",length=length(bunchafiles)) , and read files into it ----
res <- lapply(bunchafiles, myread)
myread <- function (x) {
y <- read.csv(x, as.is=T, header=T)
if (nrow(y) > 0) {
quotedate <-
strsplit(strsplit(x,"/",fixed=T)[[1]][11],".",fixed=T)[[1]][1]
a <- rep(quotedate, nrow(y))
y <- zoo(y,a)
}
return(y)
}
I now have a list of zoo'd files. Each of them is indexed by a date
which is unique. All fine so far.
Now, I want to combine all of these into one large zoo object. So I say
------ bigzoo <- do.call(rbind, res)
I now get an error .... "rbind(...): indexes overlap"... I am now
wondering how? Because when I do the foll ----- for (i in
1:length(res)) {cat(i," ",unique(index(res[i][[1]])),"\n")}
I see that I have unique indexes for each res.... So why is rbind
behaving thus?
