[R] Background color of symbols in xyplot
Dear R-users, I am using plot symbols given by pch=21:25 in a xyplot. The background color of these symbols can be defined by 'fill' in the panel argument, however I have a hard time to find how to define the same background color in the key. I tried different options like using the auto.key argument and modifying the par.settings, or using normal key argument plus 'fill', 'bg' or 'background'... nothing seems to do I want. What should I change in the following code to make it work ? key=list(space=bottom, points = list(pch = 21:25, col = 32, bg=15), text=list(mylegend)), Thank in advance Sebastien PS: cheng __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] background color

Maybe this is enough: plot(seq(-3,3,.01), dnorm(seq(-3,3,.01)), type=n, xlab=x, ylab=f(x), main=Normal density) polygon(x=c(-4,0,0,-4), y=c(-1,-1,.5,.5), col=red) polygon(x=c(4,0,0,4), y=c(-1,-1,.5,.5), col=blue) lines(seq(-3,3,.01), dnorm(seq(-3,3,.01)), type=l, lwd=2) Play a little bit with the polygon margins to get what you need.

[R] background color behind symbols in legend()
Hello,
I try to display coloured rectangles behind symbols in a legend (as a
background):
plot(10,10)
legend(top, c(text,text2), pch=c(21,22), fill=c(red,green),
pt.bg=black)
On the resulting graph, the symbol is not centered upon the coloured
rectangle. Is there a way to adjust their relative position, so that they are
centered? Looking through ?legend has not helped me (but I might have missed
the line where it is explained)...

Yes, you just have to write a custom strip function (slightly beyond
what strip.custom is capable of):
xyplot(y ~ x | f,
strip = function(..., which.panel, bg) {
bg.col = trellis.par.get(strip.background)$col;
## or bg.col = c(red, green) if you prefer
strip.default(..., which.panel = which.panel,
bg = rep(bg.col, length = which.panel)[which.panel])
})
This will only work when you have one conditioning variable (otherwise
'which.panel' won't be a scalar), but you haven't told us what you
want to happen otherwise.

(as would be obtained by a suitable manual combination of 'plot' and

arguments of matplot and handling similar to 'lty', 'cex' and the like
inside the function including transfer to 'plot' and 'lines' argument
list).
is the present behaviour a bug of 'matplot' or is it for some reason
intended behaviour?
The real point is that you might want to mark by rows *or* by columns,
so it's not that easy to specify a sensible default behaviour, at least
one has to think about it.
I'm aware of this: any specific behaviour could be the 'best' default
for someone. in terms of consistency, I would argue that matplot plots
columns of x against columns of y, so these columns should be
addressed. that is how 'lty' and 'pch' and 'cex' do it. the present
behaviour of 'bg' ('bg' interpreted only for column 1 of x against
column 1 of y) is not sensible.
If you want to implement it for all possible arguments, the well known
problem of huge number of arguments springs to mind as well.
that is indeed a problem, but I think mainly when reading the help
pages, which then are cluttered with many not often used graphic parameters.
Since you say the modification [...] is obvious: I think R-core
welcomes your contribution.
well, I'm not a fluent R programmer. I'm not sure if the simple minded
modification of 'matplot' would be welcome by R-core. rather, I attach
here the modified code 'matplot2' (sic!), if someone wants to use it. a
'diff' vs. the original versions shows easily the few modified lines.

RE: [R] Background color Windows device (newbie)
What you should realize is that xYplot() uses lattice, and that color theme is the default for lattice. trellis.device() has the `theme' argument that you can use to change it. The help page explains how you can change the default: theme: list of components that change the settings of the device opened, or, a function that when called produces such a list. The function name can be supplied as a quoted string. A possible use of this argument is to change the default settings at session startup, for example by setting 'options(lattice.theme = col.whitebg)'. If 'theme' is a function, it will not be supplied any arguments, however, it is guaranteed that a device will already be open when it is called, so one may use '.Device' inside the function to ascertain what device has been opened.

Thank you both for pointing out that this is a lattice plot (ie, R's version of Trellis graphics) and therefore needs something other than par(). I was able to use IE6.0 to search for trellis and find the relevant commands (after using help.start(), of course). This brings up another question: Is there a convenient way to decide whether or not the generic plot( ) is going to use regular or trellis plotting? I looked at methods(plot) and didn't find any groupedData plot methods listed, so perhaps this is the clue? -david paul __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
Re: [R] Background color(s) for groupedData plot
Paul, David A wrote: I've been using par() to check the graphics parameters associated with both plot(fitted linear model) and plot(grouped data object). AFAIK the only differences are in the $cxy, $usr, $xaxp, and $yaxp parameters but the background color for the grouped data plot is grey while the linear model plot has a white background. When I've tried par(bg = white) prior to using the plot(grouped data object) command it doesn't seem to make any difference. How can I change the grey background to something else? Much thanks in advance, David Paul __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help I guess you are using package nlme. Plots for the different GroupedData classes are produced with package lattice. So you cannot use par(). See the documentation for package lattice. After you have opened a device, you might want to use lset(col.whitebg()) or simply look into ?trellis.device how to set black and white schemes and so on.

It's there, but as the GroupedData methods, not groupedData.
require(nlme)
methods(plot)[grep('groupedData',methods(plot),ignore.case=T)]
[1] plot.nffGroupedData plot.nfnGroupedData plot.nmGroupedData

[R] Background color of plot
I'm using the parameters mfrow and mfg to display some graphics(plots)
at the same time. Although, because of the parameter mfg, the parameter
bg don´t change the background color.
What can I do to solve this?
Here is the code I'm using...
...
i - 1
for(j in 1:4){
for(k in 1:2){
limiares - tabLimiar(arrayMetricas[,i])
op - par(mfrow=c(4,2),pty=s)
par(mfg=c(j,k))
plot(limiares,main=a[i],ylab=frequencia,xlab=limiares,bg=white,col=green,col.main=seagreen,type=b)
box(which=figure,lty=solid,col=white)
par(op)
i - i+1
if(i == ncol(arrayMetricas))
break
}
}
...
Patricia.
