text plots?
Is there a way to do text plots in R?
I'd like to do some simple XY plots in R with the output in text
(ascii). For example, with gnuplot I can do the following:
echo 'set terminal dumb ; plot sin(x)' | gnuplot
To generate a simple sin wave. Since I connect to a remote Linux
machine using SSH, being able to generate a rough idea of what a plot
will look like in text would be

screen wrapping
Hello all,
How can I increase/decrease the line length for screen wrapping?
Currently when I run the following the output appears to wrap at just
under 80 columns:

large data set, error: cannot allocate vector
Why am I getting the error "Error: cannot allocate vector of size
512000 Kb" on a machine with 6 GB of RAM?
I'm playing with some large data sets within R and doing some simple
statistics. The data sets have 10^6 and 10^7 rows of numbers. R
reads in and performs summary() on the 10^6 set just fine. However,
on the 10^7 set, R halts with the error. My hunch is that

SQL like manipulations on data frames
Is there a cheat-sheet anywhere that describes how to do SQL-like
manipulations on a data frame?
My knowledge of R is rather limited. But from my experience it seems
as though one can think of data frames as being similar to tables in
a database: there are rows, columns, and values. Also, one can
perform similar manipulations on a data frame as one can on a table.
For example:

R more Unix-like?
Is there a way to stream data into R so that it can be used in a
command pipe?
Most Unix commands read data via standard input and read the script
from the command line. For example:
$ seq 1 10 | sed -e 's/^/foo /'
$ seq 1 10 | awk '{print "foo " $1}'
$ seq 1 10 | perl -lane 'print "foo $F[0]"'
In contrast, R seems to read the script

Using DBI and RMySQL
Dear All,
I am having a bit of problem using the DBI and RMySQL
package. I have already installed DBI but now I want
to connect to MySQL. So how do I do it. The CRAN
package repository does not have RMySQL windows binary
to install from?

Suitability of R for Algorithm simulations
Greetings,
Sorry for the basic question, but I am trying to find out if R is a suitable platform for what I want to do...
I am interested in creating simulations of distributed algorithms (i.e. team formation, Byzantine Generals , P2P communication modeling, mobile networks) that would be represented in GUIs. I would like to be able to instantiate an object for each node in my simulated

xy.coords(MATRIX) bug in code or documentation (PR#8937)
Hi, people.
xy.coords() does not behave like its documentation says, when given some
matrices. ?xy.coords says:
If 'y' is 'NULL' and 'x' is a [...] formula [...] list [...]
time series [...] matrix with two columns [...]
In any other case, the 'x' argument is coerced to a vector and
returned as *y* component [...]

R-generated animation of a polynomiograph
Hi, people.
Two days ago, I sent to this list a little toy for exploring
polynomiographs (yet, the mathematical formulas were not polynomials
anymore, so the name is not really appropriate).
After studying R calls, expressions and functions a bit more, I gave
myself the homework of producing an animation out of my recent toy. The
resulting animation, and also the sources, are available at:

Excel (off-topic, sort of)
Except for the ability to perform circular recalculation, I believe that the closest programming analogy to a spreadsheet is a functional programming language. Check out Haskell (or LISP or Erlang) to do what you describe.

Truncated labels in hist (PR#8864)
Hi, people. Executing the following command:
hist(rpois(100,5), labels=TRUE)
yields a graphic in which some labels are truncated (on an X11 device).
The truncated labels are those over the highest bars. The hist function
should ideally manage enough room for the labels, automatically.
(Specifying ylim solves my problem, but yet, hist could be frienlier.)

Combine matrix
Hi R user,
I am new to R, and I have a very simple question for you. I have two matrix
A and B, with internally redundant rownames (but variables are different).
Some, but not all the rownames are shared among the two matrix. I want to
create a greater matrix that combines the previuos two, and has all the
possible combinations of matching rownames lines among matrix A and B.

R 2.5.1 - Rscript through tee
Hi, people.
I met a little problem for which someone might have a solution. Let's
say I have an executable file (named "pp.R") with this contents:
#!/usr/bin/Rscript
options(echo=TRUE)
a <- 1
Sys.sleep(3)
a <- 2
If I execute "./pp.R" at the shell prompt, the output shows the timely
progress of the script as expected. If I use "./pp.R | tee

Matrices given to pt? [was: [R] for loops and counters]
Hi, people.
I was a bit intrigued by the message quoted below. Indeed, if pt() is
given a matrix, it returns a matrix. Should this feature be documented?
?pt speaks about "a vector of quantiles", and says nothing about the
type of what it returns.
The same might presumably apply to other distribution-related functions.

Mere chat on vectorisation matters
Hi, people. Allow me to chat a tiny bit on two vectorisation-related
matters, in the context of R. I'm curious about if the following ideas
have ever been considered, and rejected already.
First is about using the so-called Duff's device for partially unrolling
loops. I did not overly check in R sources, and am not familiar with
them anyway, but the only usage I saw is within
