2-15.2 Windows 32-bit version anywhere ?
Dear R Users,
I am working in an environment in which I am not able to compile any code. Sad, but true.
Is there a Windows 32-bit version of 2-15.2 anywhere ? I am currently unable to use packages Matrix and mgcv because they appear to have been compiled for 2-15.2 but only 2-15.1 is available for download from the regular CRAN websites.
Thanks in advance,

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,

Automatic placement of Legends
Dear R-Users,
I am looking for a way to get legends placed automagically in an empty
spot on a graph. Additional complication comes through my useage of
multiple graphs on the same plot through mfrow.
Is there a way to achieve this in R ? I have legends for each of the
sub-plots.
Many thanks in advance,

Information on the number of CPU's
Dear R Users,
I am on Windows XP SP2 platform, using R version 2.7.2 . I was wondering
if there is a way to find out, within R, the number of CPU's on my machine
? I would use this information to set the number of nodes in a cluster,
depending on the machine. Sys.info() and .Platform do not carry this
information.

Plotting three time series on the same graph
Dear R Users,
I would like to plot three time series on the same graph, two axis on the
left and one axis on the right.
The time series that I am graphing on the left do not share a similar
scale: one has a range of 1:100 and the other a range of 25000:70000. How
can I display the tick marks for both on the left hand side without
superimposing them, i.e. one set of tick marks in black right

How can I execute a .R/script file
Dear R-Users,
I've written a number of functions in a .R/script file. I would like to
call those functions from another script file. How can I execute all the
code in a script file so that the functions are available for use in my
other script file ?
I have tried help.search("script") and various Google alternatives but
couldn't come up with anything.

col.names ?
Dear R Users,
A bit of an elementary question, but somehow, I haven't been able to
figure it out. I'd like to changes the column names of a data frame, so I
am looking for something like col.names (as in row.names). Could someone
please show me how to change the column names of a data frame ?

Sorting a list
Dear R Users,
A bit of a simple question, but I could not find the answer thru google
("sorting lists r cran","how can i sort a list r cran") or RSiteSearch...
how can I sort a list ?
One imagines something like sort.list would do the job, but that's not the
one.
> foo<-list(a=10,b=2,c=3)
> sort.list(foo)

Landscape mode for pdf
Dear R Users,
I would like to get the pdf() command to create graphics in landscape
mode, as I am plotting 8 graphs in 2 rows and 4 columns. This is being
generated for an a4 printer (so I also use the paper="a4" command). Is
there a way I can ask pdf() to generate the document in landscape mode ?

Converting the results of granger.test into a matrix
Dear R Users,
The granger.test command in the MSBVAR package estimates all possible
bivariate Granger causality tests for m variables. If one passes a data
frame with 3 rows, it returns 6 granger tests in two rows, one for the
F-statistic and another for the p-value.
For example:
> a<-rnorm(1:10)
> b<-c(lag(a),rnorm(1))
> c<-c(lag(b),rnorm(1))

smooth function advice
Dear R Users,
I am looking for a smoothing function with the following characteristics
for a time series of data:
- at each date, should only use data up to that date (so, right aligned
and not centered)
- should return a smoothed series of length equal to the original time
series:
- for a one-day time series, just returns that day
- this means the front part of the series will

I am trying to do a 3d plot where the x,y,z axes intersects with the origin

lapply item names
Dear all,
I am using lapply to generate plots by applying a plot function to a list of

Is there a way to call the list item number inside the plot function so that
I can identify each graph?

which alternative tests instead of AIC/BIC for choosing models
Dear R Users,
I am looking for an alternative to AIC or BIC to choose model parameters.
This is somewhat of a general statistics question, but I ask it in this
forum as I am looking for a R solution.
Suppose I have one dependent variable, y, and two independent variables,
x1 an x2.
I can perform three regressions:
reg1: y~x1
reg2: y~x2
reg3: y~x1+x2
The AIC of reg1 is 2000, reg2 is

Yule Kendall resistant measure of skewness
Dear R Users,
Is anyone aware of a package which calculates the Yule Kendall resistant
(to errors,outliers) measure of skewness ? An easy calculation to perform,
but was just wondering if a package exists (as the contents of that
package would probably include other cool things I would also be
interested).
Thanks,
