Dear useRs, I'm trying to plot spray quantities against dates, and label the points on the plot. Basically quite simple, but sometimes two chemicals have been used and are listed in separate rows in the table as below; then the labels are written on top of each other. > spray SprayDate PD Trt Qwater Qai 1 2005-03-09 Spidermites Pegasus 1300 1.04 2

I'm trying to select a subset of a dataframe while dropping some factors. While the dataset gets smaller all Factor levels remain and I need to get rid of them. Strangely enough, I am almost certain that the same code on the same data worked OK earlier today - and it is not the first time that I'm not able to replicate earlier results with this command (I know, I might just be going

Full_Name: Bob O'Hara Version: 2.6.0 OS: Windows XP Submission from: (NULL) (88.112.20.250) Using horizontal=TRUE with boxplot() confuses it as to what is an x- or y-axis. At least, xlim= and ylim= are the wrong way round, log="x" (or "y") and xaxt= work as expected, I haven't looked at anything else. Some code to see if you can reproduce the bug (or discover

Hey, Here is a snippet that generated a boxplot and separates points so that they do not overlap. I have a problem to avoir text overlapping. Any help would be helpful. > attach(InsectSprays) boxplot(count ~ spray, data = InsectSprays, outpch = NA) stripchart(count ~ spray, data = InsectSprays, vertical = TRUE, method = "jitter", pch = 21, col =

I have data in a file named hands.dat, which is given at the end of this question. (It's from a stats textbook example on anova). I'd like to do an aov on this, which I guess would be d <- read.table("~/hands.dat", header=TRUE) aov(Bacterial.Counts ~ Water + Soap + Antibacterial.Soap + Alcohol.Spray, data=d) but this fails. Do I need to break d$Method up into columns for

Hi I'm using R 2.0 in SuSE 9.2. When I plot data as a boxplot, the boxes appear on the plot in alphabetical order (of group) rather than the order in which they appear in the data. So far, the only thing I can do to fix this is to prefix the group labels with a,b,c...etc to trick R into plotting them in the right order. Can sorting be turned off? How should I address this sensibly? Thanks

I am using R 2.2.1 on a Windows 2000 PC. When I do a grid() after the boxplot it overprints the boxplot: > boxplot(count ~ spray, data = InsectSprays, col = "lightgray") > grid(nx=NA, ny=NULL) > if I try the panel.first > boxplot(count ~ spray, data = InsectSprays, col = "lightgray", + panel.first=grid(nx=NA, ny=NULL)) > I can see the grid flash

Hi everybody! I recently tried out Wine, and decided to write an article about it. Well, that means I need to get some interesting windows apps working, so far it's only Notepad and Solitaire (won't make anyone cheer). The problem is, when I try to start any installer.exe file, I get some rows of nonsense ("fixme pthread...blabla") and then it exits with the message that it

Dear all - With the following code I get Boxplots and Stripcharts in one Plot: with(InsectSprays, boxplot(count ~ spray, boxwex = 0.3)) with(InsectSprays, stripchart(count ~ spray, col = "red", vertical = TRUE, add = TRUE)) But the dots from the stripchart are plotted over the Boxes. Is there any possibility to have Stripchart and Boxplots side-by-side, i.e. to move boxplots and/or

I'm still having trouble getting to grips with time classes. I wish to calculate the difference in days between events. Browse[1]> insp.j$First [1] "2002-02-19 13:00:00 NZDT" Browse[1]> spray.j$Date [1] "2001-11-29 13:00:00 NZDT" Browse[1]> insp.jk - spray.j$Date Time difference of 82 days If I save insp.jk to a vector, I get a nice useful value of 82.

Dear R-users, Does anyone knows how I can order my serie of boxplots from lowest to highest median (which is much better for visualization purposes). thanks in advance, willem [[alternative HTML version deleted]]

Hello everyone! I downloaded CodeWeavers wine the other week and had it up and running in the instant of a sec. So, I mounted my Cd and installed StarCraft with no problems (except all this jibbrisch about missing fonts). Happy as a newborn daddy I started it up, and noticed that since I couldn't fill in a userid for playing, I couldn't play. it turned out that all my keyboard pressing

Hi, I would like to use the beanplot() function from the beanplot package. Unfortunately, I can't find out how to suppress the dashed horizontal line, that shows the overall mean. In the help I've found the argument "overallline", but it only allows for "mean" or "median" . I have tried overallline = F, overallline="n", and

That sounds like an esthetic argument, not a logical argument. ?Heap spraying? sounds scary, so let?s fix it! What I want to know is, what can you *do* with a sprayed heap caused by an unprivileged executable? Realize that as soon as a second executable starts, it doesn?t see the sprayed heap...

Dear List-Members, I would like to produce a ordered boxplot in which the categories with the smallest median are plotted at the left end and the box with the largest median at the right. Thanks in advance for any advices Thomas H.

HI there, why these lines of code are correct plot(count~spray, data = InsectSprays) plot(InsectSprays$count) but this return an error: plot(count, data = InsectSprays); "data" method is not implemented in plot?!

Quite a simple one really! When I run boxplot(), the labels on the X axis are horizontal, and I want them vertical. So I did: par(las=3) boxplot(...) And my labels just aren't there anymore.... Any help???
