Multiple series plot with different 'type' argument
Hi:
I need to plot two time series in the same plot and
they cover the same time range and have the same
frequency. With
RSiteSearch("multiple series plot")
i found this post by Gabor Grothendieck:

Exactly what i need except for one detail. I want one series
to be made of points and the other by a line. When I simply

Need something like multiple plots in ts.plot but then change x values
Hi:
I need to plot two data sets and then I need to change labels of xaxis. I
can manage to achieve something like it with this:
x<-data.frame(a=c(1,2,3,4,5),b=c(2,4,6,8,10))
y<-data.frame(a=c(3,4,5),b=c(1.5,2,2.5))
xts <- ts(x$b,start=x$a[1])
yts <- ts(y$b,start=y$a[1])
ts.plot(xts,yts,col=c("red","blue"))
But ts.plot does not allow to change x labels. Besides,

Spectral Coherence
Greetings,
I would like to estimate a spectral coherence between
two timeseries. The stats : spectrum() returns a coh matrix
which estimates coherence (squared).
A basic test which from which i expect near-zero coherence:
x = rnorm(500)
y = rnorm(500)
xts = ts(x, frequency = 10)
yts = ts(y, frequency = 10)
gxy = spectrum( cbind( xts, yts ) )

plotting multiple series in one plot
say we have:
> x<-data.frame(a=c(1,2,3,4,5),b=c(1,1,1.5,2,2))
> y<-data.frame(a=c(1,2,3,4,5),b=c(1,2,2,3,3))
How would I plot this so that, with the shared $a as the x-axis values, I
have both $b columns plotted together? (a comparison of the two?)
thanks.

I think this is another one of the same kind of bugs in ts:

Dear all,
I found really difficult with the time series questions, please help me with this monthly airline series!
I have run the following r code, and there is an error appeared at the end. The data files was enclosed in the email.

NFS Mount: files owned by nobody
This is one of those simple-been-doing-this-forever things that, for
some reason, has me stumped today.
When I try to NFS (v4) mount a directory, the user/group ownership shows
up as user "nobody" even though /etc/passwd has values for the correct
user names. How do I get it to mount with the correct user IDs?

We have configured asterisk to trunk with avaya with ooh323 channel driver. The sip phone registered on asterisk

plotting a subset of a time series
Dear R People:
I have the following time series and plot:
> x <- ts(rnorm(50),start=2005,freq=12)
> plot(x)
>
which works fine.
I would like to plot a subset of that time series, which I did with:
> plot(window(x,2005,2006.83))
Is there a better way to do this, please?
Thanks,

R: Help xts object Subset Date by Day of the Week
I have a xts object made of daily closing prices I have acquired using
quantmod.
Here is my code:
library(xts)
library(quantmod)
library(lubridate)
# Gets SPY data
getSymbols("SPY")
# Subset Prices to just closing price
SP500 <- Cl(SPY)
# Show day of the week for each date using 2-6 for monday-friday
SP500wd <- wday(SP500)
# Add Price and days of week together

Another quantmod question
I'm having troubles with the names of columns.
quantmod deal with stock quotes. I've created an array of the first 5
closing prices from Jan 2007. (Is there a problem that the name is the same
as the variable name? There shouldn't be.)

Math problem with xts objects
Hello,
I coming across a strange problem doing math on an xts object.
If I have an xts object of stock prices (perhaps 5 minute bars of open, high, low,close) and want to do some math, the results fail.
For example:
d$close[10] - d$open[10] works perfectly
d$close[10] - d$open[9] fails. I just get an answer of "numeric(0) Index: numeric(0)".
My guess is that xts is breaking

xts dates spacings
Hello!
Please help - can't find any options how to remove very big spaces between
two dates containing intraday prices plotted by plot.xts. It looks like the
following: on the left side of the plot window is the first bunch of points,
the same is for the right hand side and a long line connecting them in the
middle. I would want to merge them (cut spaces) somehow.

Time Series Have Date Show Days of the Week

Creating regularly spaced time series from irregular one
Hello,
I have a series of intraday (high-frequency) price data in the form of POSIX
timestamp followed by the value.
I sucesfuly loaded that into "its" package object. I would like to create
from it a regularly spaced time series of prices (for example 1min, 5min,
etc apart) so i could calcualte returns.
There is an interpolation function locf() that for timestamp with value NA
