Controlling the length of line with abline(lm())
Hi
I just realized that when I use linear regression to draw a line through my
data points with something like the following:
abline(lm(y ~ x))
the length of the line is infinite, i.e., the line goes beyond the smallest
and the largest data values. This seems not very right to me (not to mention
it looks unaesthetic). I do not mean to imply that the straight-line
behavior of my system is

Plotting multiple continuous lines with symbols
Hi,
I am trying to plot multiple lines on one plot such that all lines are of
the same color (black) and continuous. I need to distinguish these multiple
plots from each other by using different symbols (I am using pch=). However,
all my lines are broken on both sides of the symbols. This unfortunate (and
unsightly) behavior seems to be the default. In my search of the help

Help with unstack() function
Hi Everyone,
I am trying to understand the unstack() function but after struggling for
two days, I have given up. More specifically, I am trying the exercises at
the end of Chapter 1 of Data Analysis and Graphics Using R by Maindonald
and Braun, 2nd ed. Exercise 18 (p. 41) asks to unstack the Rabbit data frame
from the MASS package to get a certain data frame that is shown in the
exercise.

Superscript/Subscript in main title
I have been trying to figure out how to get superscript/subscript in the
main title for a plot. I have tried various approaches and suggestions but
none of them work. I am trying to get the following as the main title of my
plot:
Emission of CO2 with time
(but note that 2 is subscript.)
I have tried

Help with axis labels
Hi
I have patched together (from various sources) the following code to get
semi-logarithmic plot. Unfortunately, my labels come out also at
intermediate places between 10^2, 10^3, 10^4 etc. Since I put the code
together from various sources and do not understand fully how the code is
working, I have not been able to get rid of the labels like 10^1.69897,
10^2.69897 etc. I would appreciate if

Specifying fonts in R
Hi
I am a novice user of R. I got hold of "R Graphics" by P. Murrell the other
day and am trying to follow examples in the book. In chapter 3, the section
on font specification gives 16 "basic" font families and face combinations
available in R (Figure 3.9). However, the book also warns that even if a
font specification is given, it does not mean that the font will always be

R Packages and Permanent Datasets creation

Kalman Smoothing - time-variant parameters (sspir)
Dear R-brains,
I'm rather new to state-space models and would benefit from the extra
confidence in using the excellent package sspir.
In a one-factor model, If I am trying to do a simple regression where
I assume the intercept is constant and the 'Beta' is changing, how do
I do that? How do i Initialize the filter (i.e. what is appropriate to
set m0, and C0 for the example below)?

S4 'properties' - creating 'slot' functions?
Dear R users!
Several languages like C# or VB allow one to create properties; typically
these are under 'get', 'set' tags. My question is this really, what are
similar or comparable strategies in R, and what might be preferred? I have a
couple of situations where I want a certain computation to belong to a
class, but I do not really want to seperate it out to a stand-alone

Using the lazy data mechanism
Dear list members,
I'm trying to use the lazy data mechanism with the car package, so far
without success. The data sets are in the source package's data subdirectory
in the form of compressed .rda files, and I added the directive LazyData:
yes to the package's DESCRIPTION file.
I suspect that the problem is that the package has no namespace, but I've
