patch proposal for plot.ts
Hi all.
Currently, if you try:
> lag.plot(1:10)
you get superposed labels '1' and '10'. Things go worse in more extreme cases:
x <- ts(1:10)
x1 <- lag(x, 4)
plot(x1, x)
This is due to a mistake in plot.ts. My suggestion is the following
really minimal patch to plot.ts:

ts.intersect bug?
This code gives an error:
a <- ts(1:10, start=0, freq=10)
b <- ts(1:10, start=1, freq=10)
ts.intersect(a,b)
This one works normally (and correctly):
a <- ts(1:10, start=0)
b <- ts(1:10, start=1)
ts.intersect(a,b)

P.S. How to switch off italian error messages to post on r-help?

creating lagged variables
Hi all.
I'm looking for robust ways of building lagged variables in a dataset
with multiple individuals.
Consider a dataset with variables like the following:
##
set.seed(123)
d <- data.frame(id = rep(1:2, each=3), time=rep(1:3, 2), value=rnorm(6))
##
>d
id time value

barplot can put legend in wrong place, request option to override that (PR#13265)
This in an enhancement requestion, to add the capability to pass
arguments through barplot() to legend(). I've created a version that
does this.

ts.plot data labels
Dear R users,
I am trying to put labels on the data points on a ts.plot.
I have tried:
ts.plot(df.ts, gpars=list(xy.labels=colnames(df.ts), xlab="group", ylab="level"))
which plots fine but gives no labels
xy.labels=TRUE
also plots without labels
I also tried using text() but got an error

Problem with logarithmic axes labelling
Dear R-helpers!
Using logarithmic axes sometimes results in an odd labelling.
In some cases, only half of the axes do have labels. Hmmmm.
I've played around with par(lab=c(5,5,7)) but that didn't help.
An example:
---- begin example ----
x <- c(0.12, 0.3, 0.53, 1.1, 1.8, 2.6, 4.5)
y <- c(0.012, 0.021, 0.032, 0.055, 0.1, 0.2, 0.35)

idea for GSoC: an R package for fitting Bayesian Hierarchical Models
Dear R developers,
these days I'm working on some R code for fitting completely generic
Bayesian Hierarchical Models in R, a la OpenBUGS and JAGS.
A key feature of OpenBUGS and JAGS is that they automatically build an
appropriate MCMC sampler from a generic model, specified as a directed
acyclic graph (DAG).
The spirit of my (would-be) implementation is instead more focused on
experimentation

The plot function is generic so the actual function call depends on what
arguments you give it:

labelling plots with ancillary data in data.frame
Hi All,
I am busy using R to do some regression modelling and have been using plot(x,y,"") to visualise my variables. I would now like to label my points using data stored in the data.frame used for the regression analysis. For example each of my data points is made up of a field measured forest volume value and a remotely sensed vegetation estimate (NDVI). Each point is an enumeration

bug in plot.ts?
Dear all,
I think I have found a buglet in plot.ts
plot.ts(x=1,type="n") # correct: does not show the plot
plot.ts(x=1,y=1,type="n") # not correct: does show the plot
I did not investigate the problem in depth but it could be related to
the switch xy.labels, in fact
plot.ts(x=1,y=1,type="n",xy.labels=TRUE) # does show the plot

escaping 'comment' chars in example sections
Dear list,
I've noticed that, when writing examples in an Rd file, you need to
escape the '%' character, even if it is valid R code.
I can see maybe this is the intended behaviour, but I found it a bit
surprising, and leads to cryptic error messages from 'R CMD check'.
The relevant section in the "writing R extensions" manual isn't clear
on that point either.

R-2.6.1 is released
I've rolled up R-2.6.1.tar.gz a short while ago.
This is a maintenance release and fixes a number of mostly minor bugs
and platform issues, as well as a couple of major problems.
Probably, the most important issues were
- save-to-postscript on Windows
- tcltk event loop with X11
- build issue on recent MacOSX
See the full list of changes below.

problem plotting "ts" in a data.frame
Hello:
I'm having trouble plotting an object of class "ts" that is in a
data.frame. I can do it with(data.frame, plot(...)) but not with
plot(..., data.frame); see the example below.
This work around gets me past this problem. However, I thought
the R Core team might want to know about this if they don't already.

variance from correlated observations
Hi all.
A statistical question. I have to estimate the variance of the sum:
X(1) + X(2) + ...+ X(n)
from an observed sample, where X(i) are *correlated* and not necessarly
identically distributed. Someone can suggest a simple strategy
(I hope by exploiting some already present R package) for obtaining such
estimate from an observed vector X[1:n]?
Tnx all,

Wishlist: mention Vectorize in 'outer' man page (PR#10490)
Full_Name: Antonio, Fabio Di Narzo
Version: 2.6.1
OS: linux
Submission from: (NULL) (213.140.16.187)
In 'outer' man page, there is no mention of the Vectorize function.
Moreover, I think it isn't underlined enough that the FUN argument to 'outer'
must be a vectorized function (doc speaks about a function which has to 'operate
elementwise').
