Lattice zoo plot: no x ticks on first panel
Hi all,
I want to use lattice v0.17-4 on R 2.6.2 to draw a panel of time series of zoo objects (zoo v1.5-0). Everything works until I try to separate panels a bit and show only the bottom axis line with tick marks on every panel (but not axis labels, which I want only on the bottom panels).
I've tried several approachs, and the best I've got for showing only the bottom axis line and

fine grain tick marks for zoo plots
Dear R Users,
I am trying to get plot.zoo to place monthy tickmarks/labels for a time
series which spans daily data going back a bit over a year. Right now, I
am getting only one tick mark on the x-axis for the beginning of 2008. How
can I force plot.zoo to place more regular x-axis tick marks on a monthly
basis ?
Thanks in advance,
Tolga

plot.zoo labels
I would like to know if there is a way to use plot(zoo) and suppress the
label text to increase the amount of the screen that if for the plot and
not the labels. I tried xy.labels=FALSE, but that had no effect. Thanks

warning upon automatic close of connection
I noticed that under R 2.6.0 there is a warning about closing the connection
in the code from this post:

which is evidently related to the following from the NEWS file:
o Connections will be closed if there is no R object referring to
them. A warning is issued if this is done, either at garbage

is there a way to avoid "traveling" grid?
Hello!
If you run the whole code below, it'll produce a stacked diagram. And
it looks good - because the tick-marks are aligned with the grid.
However, if I stretch the graph window, grid becomes misaligned with
the tickmarks. Or, rather, it seems aligned for the first and the last
tick mark, but not for tickmarks in between.
Can it be addressed?
Thank you!

problem with tick graph
Dear all,
I'm having problems with the tick of my graph. I'mpcombining lines and

For my I'm using the function axis combined with the function pretty to have
more efficient tick, but all my tick (for example, 300 as my max tick and -100
as my min tick) are not printed on my graph.
So I would like to have for the left axis the seq from 0 to 100 (with 0 and

zoo timeseries plot; minor tic mark level control
I cannot figure out how to tune the minor tic marks on the date axis of a
zoo plot.
I read hundreds of CSV files from a zip archive transparently. The
time/date strings I convert to POSIXct format, order them and then make a
zoo object as there may be cases which have unequal time stamping. As

Newbie: Barchart Gray with White Grid?
Hello,
I'm just getting in to R, been reading manuals (thanks to all who
provided pointers to good docs!), and messing with different commands.
I'd appreciate a little help with this exploration, and I hope that my
question is relatively easy to answer (probably, there's a simple way
to do what I'm working toward).

Working with quantmod chartSeries and plot.zoo
Hi all,
I'm a newbie to R and it has been very helpful to use your website.
Unfortunately I've been struggling with my code now for two days so I wanted
to ask few questions. I've been trying to create nice graphs to put into a
pdf sheet but I'm having little problems with all the packages I've been
using. So what I want to accomplish is create one pdf sheet with three

irregular time series and multiple, overlaid plots
I am new to R and am trying to solve the following problem:
I have a data file containing tick-by-tick, millisecond level prices for
some stocks. I have another file or two containing orders and trades,
again, with millisecond time-stamps. Both of these files are irregularly
spaced and the time stamps are in an iso format (<date>
<time>.<millisecond>)

Can't format x axis on a stacked plot of a zoo object
As an example data set:

adding a legend to the plot (but outside of it)
Hello!
My code below creates a data frame and a plot for it.
However, I can't figure out how to add a legend that is not ON the
plot itself, but outside of it (e.g., to the right of my graph or
below it). I tried something: I put a line par(xpd=T,
mar=par()$mar+c(0,0,0,4)) right before my plot command), but that
screwed up all my gridlines - they covered all graph and do not
coincide with

Adding two files into one and vlookup
I have two files with dates and prices in each. The number of rows in each of
them will differ. How do I create a new file which contains data from both
these files? Cbind and merge are not helpful. For cbind because the rows are
not the same replication occurs. Also if I have similar data how do I write
a vlookup kind of function? I am giving an example below:

Construct time series objects from raw data stored in csv files
Hi,
I have time series data stored in csv files (see below for an example of the
data). I understand that in order to analyze my data in R, I need to first
transform it into a ts object. Howeve, I could not find an example on how
exactly to do that. Is ts the only function I need? What are the steps that
I need to go through to build a time series object from raw data like this?
Thanks,
Tom
