Title obscured when using par(mfrow) (PR#3463)
I want to put multiple plots on a page using par(mfrow), then a single title at
the top. This should work, but doesn't:
R> par(oma=c(0,0,4,0), mfrow=c(3,4))
R> for (i in 1:12) {plot(1); title(i)}
R> ## text(10,10, ".")
R> par(mfrow=c(1,1), oma=c(0,0,1,0))
R> title("Main Title")
The main title does not appear. However, uncommenting the third line

par: mar and mgp dead?
I just installed 99.0a, and I can't set mar and mgp:
> par(mar(2,2,.1,.1))
Error in par(mar(2, 2, .1, .1)) : couldn't find function "mar"
I had the same happen with mgp.
Are these bugs or a problem in my installation (everything else seems
OK)?
Is R core going to kill mar and mgp? If so, how should I fix the
huge margins and huge space between axis title and axis? Try this

small first graph of par(3,2), other 5 are correct
Hi,
I'm trying to produce 6 graphs on a single page using code I've borrowed
from an example by Paul Murrell:
(http://www.stat.auckland.ac.nz/~paul/RGraphics/custombase-xmastree.R).
It involves placing 6 horizontal barplots on one page and adding common
labels.
The problem is the first graph in my figure (the one in the (1,1)
position) is smaller than the other 5. A toy example is

sudoku
Any doubts about R's big-league status should be put to rest, now that
we have a
Sudoku Puzzle Solver. Take that, SAS! See package "sudoku" on CRAN.
The package could really use a puzzle generator -- contributors are

as.character.factor when the factor contains "NA"
as.character.factor contains this line (where cx=levels(x)[x]):
if ("NA" %in% levels(x)) cx[is.na(x)] <- "<NA>"
Is it possible that this is no longer the desired behavior? These
two results don't seem very consistent:
> as.character(as.factor(c("AB", "CD", NA)))
[1] "AB" "CD" NA
> is.na(.Last.value)[3]

outer(-x, x, pmin) cannot allocate
R> x <- 0. + 1:8000
R> y <- outer(-x, x, pmin)
Error: cannot allocate vector of size 1000000 Kb
Why does R need to allocate a gigabyte to create an 8000 x 8000 matrix?
It doesn't have any trouble with outer(-x, x, "+"). Thanks.

R help files -> S-Plus; par('mgp')
Thanks to Brian Ripley I have been using R utilities for
some time for converting S-Plus UNIX nroff help files
to .Rd to .html files. .Rd files seem to be the most
natural format for help files and this format is probably easier
to maintain than nroff, so I would like to start
using .Rd files as my master documentation format
if anyone has a utility for going from .Rd to nroff.
I guess I could

par(mgp) - unexpected behaviour (PR#6045)
Full_Name: Nicholas Boers
Version: 1.8.1
OS: Windows XP Home Edition, Debian GNU/Linux 3.0
Submission from: (NULL) (24.68.84.10)
mgp[2] specifies the axis labels' margin line relative to that of the axis line

The following code demonstrates my observation:

pointsize in png graphics
Dear all,
I'm trying to produce 2 png files, one consisting of an image plot and a
color-table (also an image plot) and the other one consisting of 4 image
plots and a color table. I'd like the color table to be exactly the same.
The way I proceded is the following:
for one plot and the color-table
png(file = png.file, width = 650, height = 800, pointsize = 16)

Bug in "[<-.matrix"? (Was: Feature Request: "matrix[1:10,1:10, block=F] <- 1:10")
Thanks to David Meyer [david.meyer@ci.tuwien.ac.at] and David Brahm
[brahm@alum.mit.edu] who suggested:
m[ cbind(index.i, index.j) ] <- vals
This works fine for the example I gave.
Unfortunately, this approach doesn't extend to using the row and column
names to make assignments:

Floating point imprecision in sum() under R-2.3.1?
After upgrading to R-2.3.1 on Linux Redhat, I was suprised by this:
R> x <- c(721.077, 592.291, 372.208, 381.182)
R> sum(x) - 2066.758
[1] 4.547474e-13
Now I understand that floating point arithmetic is not precise, but
1) the result is exactly 0 in R-2.2.1 (patched) on the same machine,
2) .Machine$double.eps = 2.2e-16, so the error seems quite large.
Also note I get the same

question concerning par("plt") and par("mar")
Hello,
I have a function that changes par("plt") to plot a colorkey, and upon returning resets the original value.
Unfortunately this changes the size of the plots when I change the layout. A simplified example:
par(mfrow = c(1, 1))
plt <- par("plt")
# .... # change par(plt) and create colorkey
par(plt = plt) # resets the default

Is r-announce alive?
I sent a message to <r-announce at stat.math.ethz.ch> last Thursday ("New package:
colSums"), and still haven't seen it echoed on r-help or on the web archive (in
fact there is no r-announce web archive for 2002). Is something broken? Did I
need to use <r-announce at lists.R-project.org> instead?

Superassignment (<<-) and indexing
In a clean environment under R-2.1.0 on Linux:
> x <- 1:5
> x[3] <<- 9
Error: Object "x" not found
Isn't that odd? (Note x <<- 9 works just fine.)
Why am I doing this? Because I'm stepping through code that
normally lives inside a function, where "<<-" is appropriate.

Subsetted 1-D arrays (PR#4110)
In R-patched_2003-10-20, subsetted 1-D arrays no longer get converted to
vectors. The NEWS file documents this change, as an indirect result of bug
report 4110. I just wanted to mention this can break code in some rather
obscure ways, such as this toy example:
R> x <- sort(tapply(1:8, rep(1:4,2), sum)) # Was vector, now is 1D array

self-split plot on multiple device
Hello!
I would plot more than 10 (this number is always different)
graphics on a figure with layout like 'mfrow=c(4,2)'.
There is some existing function able to open the right number of
device if number of graphics is done or I have to build it myself
with some 'IF.....ELSE.....'?
Thanks.

ARMA and ARIMA modeling
I'd like to play with ARIMA models of stock prices, but I am a complete novice.
Could some kind soul explain the relationship among packages "ts", "tseries",
"dse", "dse2", and "fracdiff"? Are they 'competing' products or does one
depend on another? Where would be the best place for a novice to begin?
Thanks for any advice.

Daylight Savings Time unknown in R-2.2.1
Under R-2.2.1, a POSIXlt date created with "strptime" has an unknown

This is true on both Linux (details below) and Windows. It did not
occur under R-2.1.0. Any ideas? TIA!
