[R-SIG-Finance] Problems with xts and plotting charts in quantmod

[Brian G. Peterson]

at least part of your problem now is that you're storing the data as 
character, rather than numeric.

in your as.xts call, you'll want to remove the first column in the 'x' 
argument,

e.g.

y <- as.xts(x[,-1], order.by=as.POSIXct(x[,1],...))
# the above is not reproducible, it is missing the format argument at least

I also see that you have spaces in your character data, so you may need 
an as.numeric in there too.

Another way to do it would be to make sure that read.csv sees the 
columns as numbers rather than character, which proably has to do with 
your choice of separator.

Regards,

Brian
