RMySQL performance over RODBC
R-help list,
I ported some R code from MS Windows PC to sun-solaris. Both do queries on
the same
MySQL database.
PC version of R is 1.6.1 and solaris version is 1.6.0. I use RMySQL_0.5-0
(on solaris)
and RODBC 1.0-1 on PC to connect to MySQL. The PC version took about 65
mins. to run
wheras the Solaris (SunOS 5.7) version took 375 mins. (> 6 hrs). R and
RMySQL are

Enright/Chi-square periodogram / periodicity
I am trying to compute the periodicity of a time series.
I would like to know which function in R does it.
Also, how do I plot a Enright / Chi-square periodogram using R ?
( Enright, J.T., 1965, Journal of Theoret. Biol. 8,426-468)
Greatly appreciate your help.
Thanks in advance,

How do I edit the x-axis on a time series plot?
I am merely trying to reproduce Figure 1.2 of Chris Chatfield's 6th
edition of his The Analysis of Time Series: An Introduction (page 2).
The S-PLUS code is on pages 305-306. I am almost there but I am having a
heck of a time trying to modify and change the x-axis per the book. The
book shows the x-axis with 10 tick marks, correctly positioned, and
labeled "Jan 53", ...,

RODBC - dsn specification
Happy New Year to all in the list!
I am trying to issue an SQL query to a database from R using
RODBC (on Windows). The data source file is on my PC hard
disk : C:\Program Files\ODBC\sql.dsn
The "\" character does not get interpreted properly in R - it
is removed from the file-spec string or if I specify "\\" it
appears as such with a syntax error in

data format of x in x <- sqlQuery()
All
When I read data into an R variable x using RODBC command:
x <- sqlQuery(channel,"select a, b from tabl",as="data frame")
and view x, I get 3 columns the first one being the index of
the rows in x.
What options do I use in sqlQuery so as not have the index in x ?
How do I get rid of the index otherwise.

Stacked plots with common x-axis and different y-axis
Is there a place that shows how to create two plots that are stacked on top of each other where they share a common x-axis scale, but have differnt y-axis scale?
Say have the following data: airquality
Stack plot(airquality$Day, airquality$Wind) on top of plot(airquality$Day, airquality$Temp).
I am interested in stacking the two on top of each other with no seam, or plotting the two lines with

R and computer heat
Hi,
I noticed the temperature of my laptop rises sharply during execution of a
long R script that generates several hundred plots, all of them saved to
files. No screen output. Temps reached above 90 Celsius degrees in the box
and above 80 C deg in the processor. The machine turns on cooler at maximum
speed and exhaled air is really hot. Tried similar operations (batch

Wishlist: more flexible handling of tick labels in axis.Date (PR#7913)
Full_Name: Gavin Simpson
Version: 2.1.0-patched (1-Jun-2005)
OS: Linux (Fedora Core 3)
Submission from: (NULL) (128.40.32.76)
axis.Date() insists on labelling tick marks. It could be made more flexible by
allowing the user to specify if they want the ticks to be labelled, for example,
to add un-labelled minor ticks for "months", added to a plot with "years"
labelled. The user

Changing x-axis when dealing with time
Hi,
I am plotting data in which the x values are a timestamp. I am trying to
change the x-ticks so they will be in specified hours of the day, but it
always start from hour 4 of the day. And I need it to start from the
beginning of the axis (at x=0) and then each tick be on the interval I
specify.

lattice: axis ticks, axis alignment and remove axis from plot
Hi there,
I'm a bit confused concerning the axis tck setting in the lattice
package as the ticks on left sided axis aren't
drawn at all with the following setting:

i = runif(20))

datetime on x-axis of plot
Hello, I'm reading Time Series Analysis and its Applilcations with R Examples
and I have a question...
I notice that in the book there are timeseries plots but without the x-axis
being labeled with dates. They are just numbers 1,...50,...100, etc. How
do I get the date to show up on the x-axis?
Here is my dateframe:

What is the equivalent function in R to xyplot in S?
Page 140 of MASS uses the function xyplot. But I don't find it in R.
Is there a package that I should load to use xyplot. Or there is a
function with a different name in R that does the same thing as xyplot
in S.
xyplot(Gas ~ Temp | Insul, whiteside, panel =
function(x, y, ...) {
panel.xyplot(x, y, ...)
panel.lmline(x, y, ...)

Hashing and environments
Hi,
I'm trying to write a general-purpose "lexicon" class and associated methods for storing and accessing information about large numbers of specific words (e.g., their frequencies in different genres). Crucial to making such a class practically useful is to get hashing working correctly so that information about specific words can be accessed quickly. But I've never really
