changing the magnification of axis annotation
Hi all,
how do I change the magnification of xaxis annotation? I need a smaller
axis text size in some of my plots. I tried cex.axix=0.5 in plot(), but
this doesn't work.
Thanks, Sven

Why is.integer() doesn't work with single values?
Hi all,
I don't understand the behavior of is.integer():
> x <- integer()
> is.integer(x)
[1] TRUE
> x <- 10
> is.integer(x)
[1] FALSE
> x <- 1:10
> is.integer(x)
[1] TRUE
Why is.interger() returns FALSE if x has only one element? And how can
someone check if x is an integer but contains only one value? (R 1.5.0
on Linux i386)
Thanks, Sven

replacing values in a vector
Hi all,
there is a vector v with several NAs. I want to create a new vector n of
the same length as v and the same NAs as in v and tried this:
n <- vector(length=length(v), mode="numeric")
replace(n, which(is.na(v)), NA)
but this does't work, all values in n are 0. What went wrong?
Thanks, Sven

How to test a model with two unkown constants
Hi all,
suppose I've got a vector y with some data (from a repeated measure
design) observed given the conditions in f1 and f2. I've got a model
with two unknown fix constants a and b which tries to predict y with
respect to the values in f1 and f2. Here is an exsample
# "data"
y <- c(runif(10, -1,0), runif(10,0,1))
# f1
f1 <- rep(c(-1.4, 1.4), rep(10,2))
# f2

Maybe OT: large fonts in eps-figures
Hi there,
if I copy an x11() graphics device to an eps-file (with dev.copy2eps())
the font in the legend is very large and doesn't fit to the legend box
in the eps-file (same with a postscript file). I'm not sure if this is a
R problem rather than a ghostscript one.
But is there a way to solve this problem in R or depends this on my
ghostscript installation?

comparing elements in a vector
...(d1-d2)!=0
I think d3 is the final vector you wanted.
I didn't test it, so I'm not sure my logic is right, but I think this is
definitely a path you can take...

Is there a "by()" function in R like in S?
Hallo R-users,
I'm a R (release 0.65) novice, but have read some about S. Is there a
similar function in R like the S function "by()" ?
This function groups data typically from a matrix by a variable and
applies a function on the grouped data. Example in S:
> by(data, year, summary)
where "data" is a matrix containing the variable "year". After grouping

Plotting multiple figures
Morning,
I've plotted multiple figures on one page, setup the page with n2mfrow.
This works fine, but I can't figure out how to change to a specific plot
(e.g. first row, second column) to add some details.
Thanks, Sven

Error plotting time series
Hi there,
when plotting a time series I got this error message:
Error in xy.coords(x, y, xlabel, ylabel, log) :
x and y lengths differ
In addition: Warning messages:
1: longer object length
is not a multiple of shorter object length in: vx.1[int.lr] + (-1) *
vx.2[int.rl]
vx.1[int.rl] and vx.2[int.rl] have the same length. Does anybody know
what the warning message means?

Summary on R script editor
Thanks for the advice, folks!
Shravan Vasishth <vasishth at ling.ohio-state.edu>
Try pico.
There's no substitute for/comparison with emacs, though, IMHO.
but just to be sure: you don't have to have ESS to use (x)emacs for
editing R scripts.
Sven Garbade <garbade at psy.uni-muenchen.de>
ESS can be installed via rpm on Mandrake.

ESS is the real answer to your question, and anything else has got

(PR#1287) seek was ignoring the `origin' argument (was
...ur request was to reposition to the beginning of
the file, and that is what happened.
This was already fixed in R-patched: from NEWS there:
o seek() on file connections was ignoring the `origin' argument.
It's always worth looking at the current patched version.
