Let us assume you are running under X11, so you are invoking

Installing R on Knoppix
Knoppix is a small LINUX distribution
(http://www.knoppix.net/) runnable from a CD (without
an installation) It can be also installed on a hard
drive from a single CD. The idea was to reuse an old
laptop with 6gb hard drive and 128mb memory.
I had few days experience with
Dear R-List,
I use Sweave (which is wonderful) and I have a problem with the
strings when they are too long according to the width of the page. For
example when I do in my .Rnw document :

df1 <- sqlFetch(channel,"table1",
I don't know what kind of computer you are using.
If you are on a Mac, then this might be relevant:

Have you looked at Quantian? I think it would have saved you lots of time.

Hi Charles,
Nice iniative for Linux newbie :) Some of us may have done a few things
differently. I'll just point out one or two below. If you want to continue
this discussion, why don't we carry it over to the r-sig-debian list that is
more appropriate? I'll set the reply-to header accordingly.

Did you try
It will change the coefficients from lm and therefore their t-values but it
will not change the residuals, fitted values, R-squared, F
statistic, etc. For example, try this:
set.seed(1)
x <- 1:10
y <- x + rnorm(10)
lm0 <- lm(y ~ x) # without scale
lms <- lm(y ~ scale(x)) # with scale

Hi All,
recently I used Design Expert for some Design Of Experiment work.
I was happy with the interface to select which effects I want to see in my
experiment, and which not.
For example: I can select of course my main effects, but also if I want to see
interaction A:B, B:C, A:B:C,but not A:C.
Does the following example answer your "arima" question:
IntReg <- cbind(It=(1:48)>20, It.w=((1:48)>20)*(1:48),
It.lh=((1:48)>20)*c(0, lh[-48]) )
arima(lh, order = c(1,0,0), xreg=IntReg)
hope this helps.

Hi all,
I'm an R novice (and I'm making progress!).
I'm getting sick of looking at all my old commands though! Can I
clear the console from the command line?
I'm running a GUI version of R in Mac OSX.
Thanks in advance!

Hi, Paul:
By my lights "paste" and "expression" work counter-intuitively. But as has
been said here often, you CAN do it in R. Figuring out how might be a
challenge, but you CAN do it (whatever it is).
Here is some code that does what I think you intended. I also added some
phantom characters
Suppose one has
x <- c(1, 2, 7, 9, 14)
y <- c(71, 72, 77)
How would one write an R function which alternates between elements of
one vector and the next? In other words, one wants
z <- c(x[1], y[1], x[2], y[2], x[3], y[3], x[4], y[4], x[5], y[5])
I couldn't think of
Try bquote (I may not have followed precisely what you
want but hopefully this gives the idea). Note that you
may need to use a few judiciously placed ~ and
phantom(), as shown, in order to maintain syntax:
plot(NA, xlim = c(0, 100), ylim = c(0, 100))
avar1 <- 10
amath1 <- bquote(slope == frac(p
Try this (note that your x and y do not have the same length
and in this case the expression will recycle the shorter one
and give a warning):
z <- c(rbind(x, y))

Dear R helpers,
Is it possible to create a semilog plot in R?
I have been scanning the help archives and manuals and semilog does not
appear anywhere.
Should i use specific package?
Thanks
