similar to: two issues

On the first issue, there's a recent post you can find in the archives. It's from Deepayan Sarkar on January 2 this year. It would probably pop up on a search for "black white lattice" or something similar. The key part of his answer: I'd do something like this as part of the initialization: <<...>> library(lattice) ltheme <- canonical.theme(color = FALSE)

I really like these Trellis graphics but how do I get this code to skip the missing? logreg<-read.csv("logreg.csv", header=TRUE, sep=",", na.string=" ") attach(logreg) bwplot(yesno~bc_pcb_tot |varlist, data=logreg, main="Box Cox PCB transformation", auto.key=TRUE, fontfamily = "HersheySans" ) Dean Sonneborn M.S.

I'd like to do a simple scatter plot but instead of using the variable values on the X axis I would like to plot the percentiles. I searched in the manual for percentiles but did not find what I was looking for. I've been using SAS for several years but I new to R. -- Dean Sonneborn Programmer Analyst Department of Public Health Sciences University of California, Davis (916) 734-6656

I'm using this code to plot a smoothed line. These two columns of data really represent 4 groups and I'd like to plot a separate line for each group but have them all in the same plot. The R-Docs for lowess do not seem to indicate some type of "GROUPS=var_name" option. What would be the syntax for this? plot(AWGT ~ lipid ) lines(lowess(lipid , AWGT, f=.8)) -- Dean

I want to produce some boxplots and plot the logged values but have the axis scale in the original, not-logged scale. It seeming like I have the first few steps but I'm having trouble with the last. Here's what I'm doing (which I got for the documentation for boxplot and axis). How do I get the ticks to be labeled 2,5, and 9 of the original scale? a<-c(1,2,3,4,5,6,7,8,9,10)

I would like to add a footnote to this graph but do not see a "footnote" command in the package:lattice documentation. I would like to note the "span=.8" as the footnote. postscript(file= ?C:/Documents and Settings/dsonneborn/My Documents/Slovak/output/pcb_tables/smooth_PCB_lines_four.ps?, bg=?transparent?, onefile=FALSE, pointsize=20,paper=?letter?, horizontal=TRUE,

I am trying to create a high low close style chart but I keep getting the following error statement; "x is not a open/high/low/close time series". I've used the function is.ts and R responds TRUE but the ohlcPlot function gives the above error statement. I'm actually planning to plot some odds ratios with their confidence intervals and the hi-low-close chart should do the

I currently have 3 separate boxplots but would like to put them all in the graphic so they would have the same scale. Below are the three statements and as you can see the Y axis is weight: bwplot(AWGT~ male2 .... bwplot(AWGT ~ bin_pcb2 ..... bwplot(AWGT ~ bin_pcb2 | male2 ..... Does anyone have some sample code where they have done something like this? Thanks, Dean Sonneborn M.S. Public

I am running this code to produce some boxplots. I have every thing that I need except that I would like the whisker line to be solid line, not dashes. I have reviewed the lattice docs but have not seemed to come across this point. print( bwplot( group ~ lpcb_tot, data= data7, xlab="Log PCB", + ylab= + " G B + S M S M

I would like to produce a graph which plots a log scale variable on the y-axis but have the tick marks on the y-axis be the non log transformed values that are round like .5, 1, 2, 3, 4 etc. Has anyone done something like this in the past? How did you implement it in the code? Thanks, Dean

This is a solution I am posting for a problem that others may have. If you want to: 1. Place lattice graphics from R into an Adobe InDesign document, and 2. Use the export as eps function in R to maximize resolution (it is much better than exporting as a metafile or bitmap), and 3. Use long strings of text in your titles or captions or to label your axes. Then you will have problems because:

Would anyone with experience with the map functions know how to divide Czechoslovakia into the Czech Republic and Slovakia. They have been two separate countries for some time now.

I'm using this syntax to create data subsets for plots: subset=source=="Both". Now I would like to create a subset defined by two different variables like this: subset=source=="Both" subset=site=="home" but this syntax is not correct. The documents in the manual for subset seem to be creating whole new data files not just selecting rows based on the

I am using the R code listed below to create 4 smoothed lines on a xyplot. I'm having trouble fine tuning it. First I think I may need a black and white plot so how do I get it to plot the lines with different characters, preferable the same characters used in the key (plus, X circle and triangle). I might also be interest in a version that draws four solid lines of different colors but

I'm running some GEE models but when I request the summary(pcb.gee) all I get are rows and rows of intercorelations and they fill up the screen buffer so I can not even scroll back to see what else might be in the summary. How do I get the summary function to NOT print the intercorrelations? Thanks, -- Dean Sonneborn Programmer Analyst Department of Public Health Sciences University of

I am attempting to read in a SAS 9.1 data file. After starting R I change to the directory containing the sas data file and use the "dir" command to confirm that it is there. Then I run the following R-code: library(foreign) sashome <- "/Program Files/SAS/SAS 9.1" test<-read.ssd(file.path(sashome), "pcb", sascmd = file.path(sashome,

Hello! The question is simple: What is the escape sequence for a new line when using Hershey fonts? I obviously tried '\n' but it didn't work (see the sample below). I looked at 'demo(Hershey)' but all it only shows escape sequences for printable characters. The sample I've been using to try to find the escape sequence is below. You can comment or un-comment the

Hi all, I am trying to make tiff files of lattice plots at a resolution greater than 300 dpi required by a journal (PLoS ONE). I have tried both the tiff and bitmap functions. tiff keeps panel colors but reduces axes and tick labels so they are nearly invisible. bitmap maintains correct label size but only produces greyscale. Regular plots work fine with tiff; the problem is only with lattice

I am using lattice to make figures as pdfs: trellis.device(device = "pdf",file = "Figure6.pdf",color = FALSE) I need to specify some blank space on the left-hand margins (the pages will be bound so we need about 0.5 inch)). I have tried a number of solutions but none seems to work (e.g. par.set). Can this be done when initiating the plotting device? Or is the some other way

Also, I am wondering if there is any source where the expressions of many symbols are collected. Thanks you very much!!! Li, Xiang(Sean)
