Variable Names
Dear R users,
That's probably a silly question even for a newbie but :
Is it possible to assign variable prices as variable names ?
For instance, would something like the following work :
for (i in 1:4)
{
error.i <- some_calculation
}
so "error.i" variables would be created for i=1,2,3,4
i.e. error.1 error.2 error.3 etc. etc.

Memory management
Dear all,
I don't get it:
First of all, the help doesn't say what are the memory limits of
R. Say, what's the max heap size for instance ????
Secondly, I invoke R with the following commands each time:
rgui --vsize 30M --nsize 1000K
rgui --vsize 30M --nsize 2000K
rgui --vsize 30M --nsize 3000K

Matrix_0.8-8 and norm() function
Hello and apologies if this is a stupid question (just rejoined the list):
Has anything changed with the norm() function with the latest update of
the Matrix library?
My old code seems not to be working properly even for very simple tests
of the norm function. I get too many
"No direct or inherited method for function "norm" for this call"
messages. I am using windows, R

Time series plot orientation
Hello,
I am trying to rotate by 90 degrees a time series plot. So I need the
time axis to be the vertical one. Is there an easy way?
I couldn't guess anything from the help pages.
Apologies for a silly question.

Playwith on Mint
Hello,
I am having trouble installing the package playwith on the latest Mint
"helena",
running R version 2.10.1 (2009-12-14).
I suspect it has to do with the GTK library but as far as I can tell there
is nothing wrong with it.
Any help extremely appreciated.
I include the output:

Console Output while running scripts
Hi,
I am using 0.63.2 on Windows. I have some functions
programmed to do repetitive tasks and have some
print(variables) statements to check how my program is progressing
but get no output on screen (console) while the program is running.
I tried CTRL-W as the help says but I get no screen output
before each run terminates. Probably some kind of setting needs to be
predefined correctly.

Vectorization instead of loops problem

I am having problems vectorizing the following (i/o using a for/next/while

the y sequence before a value of 1 is

tryCatch - Continuing for/next loop after error

I am not sure I understand fully the functionality of "tryCatch" and
"try" commands and how these are used to continue a for/next loop if an
error occurs within the loop.
Can somebody point me to material (or share some code) with more
extensive examples than the ones in the help/FAQ pages?
Do explain my problem in more detail:

How can I shade the background area of a zoo time series object between specific dates?
Dear list members,
How can I shade the background area of a zoo time series object between
specific dates?
eg.
library(tseries)

"Close")
plot(SP500)
How can I produce the same plot but with a (say) red background between

and
