How can I shade the background area of a zoo time series object between specific dates?
Dear list members,
How can I shade the background area of a zoo time series object between
specific dates?
eg.
library(tseries)
library(zoo)
SP500<-get.hist.quote("^GSPC", start = "1990-01-01", quote =
"Close")
plot(SP500)
How can I produce the same plot but with a (say) red background between
2007-04-12
and
2008-05-14
?

Combining playwith with par(mfrow... ) i.e., multiple plots.
Hi,
I have the following problem:
library(playwith)
x<-ts(rnorm(100))
y<-ts(cumsum(x))
playwith({
par(mfrow=c(2,1))
plot(x)
plot(y)})
I can't make playwith identify (using the button top left) datapoints on
multiple graph plots (eg. par(mfrow=c(2,2) for a 2 x 2 frame of plots).
Is it possible any other way?
Many thanks in advance,
Costas

forecast & xreg
Dear all,
I am fitting an arimax (arima with some extra explanatory variables)
model to a time series. Say, I have a Y (dependent variable) and an X
(explanatory).
Y is 100 observations (time series) and X is 100 + 20 (20 to use for the
forecast horizon).
I can not make xreg work with the forecast function for an arima fit.
The "predict" function seems to be working but the

ctv, install.views, install.packages (& update.packages)
Dear all,
Wouldn't it be helpful if the
install.views
install.packages
update.packages
had a "downloadonly=TRUE" flag which would allow us to download the
packages and install them later (or put them in a USB stick and take
them for installation on anothe PC).
I am behind a firewall (Bank) and I have serious plroblem updating R or
installing views (Finance, Econometrics etc.
