Changing the ranges for the axis in image()
Dear all,
I can not find/understand the solution to this from the help pages:
Say we have the following script:
x<-matrix(c(1,1,0,1,0,1,0,1,1),3,3)
image(x)
How can I change the ranges on the vertical and horizontal axis to a
range of my own or at least place a box frame around the image if I
choose to use "axes=FALSE"?
Apologies for such a bsic question and thanks beforehand

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:

the y sequence before a value of 1 is

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)
library(zoo)
SP500<-get.hist.quote("^GSPC", start = "1990-01-01", quote =
"Close")
plot(SP500)
How can I produce the same plot but with a (say) red background between
2007-04-12
and
2008-05-14
?

tryCatch - Continuing for/next loop after error
Dear all,
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:
