minor tick marks
Hi !
I need a plot for data extending over several orders of magnitude on the y axis.
The following command generates a nice looking semi-log plot for my data:
plot(x,y,log="y",type="l",lty=3, ylim=c(0.01,2),yaxp=c(0.01,1,1),las=1)
I would appreciate having also minor tick marks in-between the 3 major ticks obtained with the above command. The "minor.tick" function

nested for loops
Dear Admin,
I will appreciate if you advise me an effective way to write the following R
code including nested for loops. I cannot do it by using expand.grid
function because it results with memory allocation problems.
Thanks for your time and consideration.

Call by reference or suggest workaround
I have written code to compute multi-indices in R [1] and due to the
recursive nature of the computation I need to pass around the *same*
matrix object (where each row corresponds to one multi-index). As pass
by reference wasn't the default behavior I declared a global matrix
(mat) and used the <<- operator to write to the global matrix. So the
usage would be to call genMultiIndices(3,2)

colour highlighting inputs and outputs in the R terminal?
Dear all
Is it possible to get basic colour highlighting for inputs and outputs
in the R terminal? I am looking for something similar to what GUIs
provide, such as JGR and (I think) the Windows R GUI: colouring all
inputs in red, and all outputs in blue. All this in a colour-aware
console (in my case, on Linux).
I've been looking into xterm256 and highlight, but I am sofar unable

Syntax coloring in R console
Dear all,
I am a happy user of R console, but I would like to see syntax
coloring. I use R 2.12 in Ubuntu Linux.
I have found the packages "xterm256" and "highlight", but I was not
able to figure out how to use it to highlight the syntax in console
output.
Also, I tried several GUI interfaces, but I was not able to find
something that suits me better than the default R

Rgui.exe fix for "console not found" buffer overflow problem
I'm using R on Windows XP Professional SP2.
I figured out the fix for my buffer overflow problem that did not allow me
to use Rgui.exe for about two weeks. I would keep getting "console not
found" and even when I uninstalled and re-installed got the same problem.
Here's how the problem started. In Rgui.exe, I attempted to get more
visible output in the buffer (I wanted

R (Windows version) users/developers:
While I have checked R-help/-devel mailing lists and R-bug-tracking
system, this problem has not been reported so far. I would like to know
whether this problem is specific to my machine.

link in base help file fails.
I run R on MS Windows. In R2.9.0dev, I type ?base to get "R help for package

Minor nuisance with rw1071
Hola!
Starting with rw1071, just after starting Rgui the scope is not with
Rconsole, but some other place. This means I have to do a mouse click
in the Rconsole before starting to write the first command. Since I
always forget this, I end up writing the first command twice.
This is of course only a minor nuisance, but why is focus no longer
set to Rconsole window when start-up?
