I have been using lattice xyplot and am quite pleased, and I can use the type=c("b","g") to have it print gridlines into the page, yet if I want to have a line plot with points on it, how do I get the xYplot to print gridlines (I use Hmisc xYplot because of its bands method which allows plotting of confidence intervals). Any suggestions? I have looked at the panel functions but when I try it I get the gridline...

In the example R script below, horizontal gray gridlines are drawn at y coordinates where the points are drawn with the code: panel.abline(h=y, v=xScale, col.line="gray") How do I change this so that the horizontal gray gridlines are drawn at y coordinates where the y labels are drawn? The challenge is that each panel has different y-range...

Greetings. How can I insert gridlines in the following density plot call? Must one compose a panel function? 'data.frame': 46 obs. of 2 variables: $ fallrates: num 5.2 7.1 7.1 9.8 3.7 7.5 5 6.2 1.5 2.9 ... $ prepost : Factor w/ 2 levels "post","pre": 2 2 2 2 2 2 2 2 2 2 ... library(lattice)...

...nto help files before asking. Still cannot figure it out. I think it's because I am totally confused what packages use lettice, which use trellis, etc. Sections 1 and 2 below produce the data and the data to plot. My question is about barplot in Section 3. I am trying to: 1. add only horizontal gridlines and manipulate the type and color of that line. tck = 1 is not flexible enough to do it. 2. make the legend come on top of gridlines and not under them 3. add plotted Y values above the bars Thank you very much for any pointers!

So, I was wondering if it is at all possible to: 1. Create gridlines in an interaction.plot 2. Define the font type of the legend title (e.g., regular vs. bold as in font=2) 3. Put actual values (on Y) next to each point in the graph. Thank you so much for your advice! -- Dimitri Liakhovitski MarketTools, Inc. Dimitri.Liakhovitski at markettools.com

dear all, I have a very simple question but I could not figure out.

Hi, Whats the easiest way to set a desired interval for tics on axes in R ? And will the 'grid' command put gridlines on all tics automatically ? I tend to get stuck with graphs with ranges 0-1 with only 2 tics and 2 gridlines in the 0-1 range, while I would like 10 tics (or every 0.1) tnx, Piet please reply to pvremortNOSPAM at vub.ac.be

To: silwood-r Subject: Removing lattice graph gridlines and editing label box colour Hi, Is it possible to remove the background gridlines from a lattice graph (ie graph made up of multiple individual graphs with annoying blue grid in the backgroun)? Also, Is it possible to change the colour of the individual graph label boxes? - ie the default pin...

I am using wireframe from the lattice package, with the shade option set to TRUE. When I output to PDF or Postscript, a line gets drawn around each polygon of my surface which causes ugly Moir? effects and doesn't make sense in my application (think the plot of Maunga Whau--gridlines don't make sense). This does not happen when I display on the screen-- then I just get the surface as intended. I have tried everything from playing with trellis.par.set() to changing the code of panel.3dwire, but nothing seems to remove these gridlines. Any idea would be greatly apprecia...

I've used to have a script with a barplot command it in, preceded by a png: png(graph.file,height=H,width=W) barplot(t,names.arg=breaks[2:(length(t)+1)],tck=gridlines) -- worked before R 2.6.2. When I tried it in R 2.6.2, which I have for a while but didn't run with that script, it complained, the margins too large, and I've googled the messages from our list where neither height nor width had been specified. Yet here they are specified here...

Hi all, I'm attempting to make a quite-specific plot where the axes cross at the origin and with gridlines for guidance. I've been using ablines to create the reference lines because I want a lot of control as to where they are placed on the axis. This command works very well for such control. However... These ablines don't seem to work when I specify the origin as 0,0. They go beyond the x-a...

...hist(), mostly) with white borders, white (on white background) axes, white grid *under* the bars, and both x- and y-axis labels (both the numeric or categorical label, and the axis titles...I don't quite remember the correct terms in R). I wasn't able to find a way to display only the gridlines parallel to the x-axis, or to overlay that grid on top of the bars, or to turn off the numeric labels on the x-axis without touching the y-axis, or to show the x-axis as a gray line without showing the y-axis. Has anyone done this? How? Thank you, Tom

...kage. As for now I use the following command : print(wireframe(m,main="% my title", colorkey=TRUE, col.regions=rainbow(100), drape=TRUE,aspect = c(1,1.0),ylab="y",xlab="x",zlab="z", scales=list(arrows=FALSE)),split=c(1,1,3,2), more=TRUE) How can I show the gridlines in a 3D surface plot of this type? I already tried with panel.grid, but it doesn't seem to work in combination with panel.cloud (wireframe). I also searched for information about the box.3d, without success. Thanks in advance.

Is there a way in ggplot to make a histogram with the left-hand y-axis label as frequency, and a right-hand y-axis label as percentage? Thanks! Pete

Hi, I'm having trouble editing the qplot layout. I'm using the geom="tile" option and I want to do a few things: 1. move the vertical and horizontal gridlines so that they appear on the edge of each tile (right now they're in the middle) 2. bring the gridlines to the foreground and change their color I've been playing around with the opts(...) options but so far can't get any of them to work correctly. Has anyone done this or have an exam...

I wrote a little function called bgfun that adds gridlines and a background, but it's not working with I plot using the formula. I have some theories on what's happening, but even if my theory is right, I don't know how to fix it. Someone have a straightforward silver bullet? Thank you, Gene bgfun = function(color='honeydew2',l...

Dear R Users, I have a basis question regarding the use of color in the lattice package. I read the ?barchart help page and searched the R archives but could not understand how to do it. I just need to plot a barchart using specific colors for my groups, e.g. green and red instead of the default lattice colors. How do I do that? If I say: barchart(x ~ a_factor, groups=my_groups,
