Dear all, I'm wanting to do a series of comparisons among 4 categorical variables: a <- aggregate(y, list(var1, var2, var3, var4), sum) This gets me a very nice 2-dimensional data frame with one column per variable, BUT, as help for aggregate says, <<empty subsets are removed>>. I don't see in help(aggregate) how I can change this. In contrast, a <- tapply(y,

Hello, all; I get an unexpected result when trying to plot a probability histogram with R1.9.1 on windows xp: #with the following code: > x <- runif(100,0,1) > hist(x) > hist(x, freq=F) > h <- hist(x, freq=F) > summary(h) # Length Class Mode #breaks 11 -none- numeric #counts 10 -none- numeric #intensities 10 -none- numeric #density 10

Hello all, I'm trying to do a nested linear model with a dataset that incorporates an observation for each of several classes within each of several plots. I have 219 plots, and 17 classes within each plot. data.frame has columns "plot","class","age","dep.var" With lm(dep.var~class*age), The summary(lm) function returns t-test and F-test values

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

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.

Dear, I am a newbie to R. Now I am learning to draw boxplot using graphics(). I want to highlight the median position with a round point and the value left (or on the top of)to the point. Please kindly share the command and thank you. Elaine [[alternative HTML version deleted]]

Estimados amigos, mi pregunta es bien directa, a ver si alguien me puede ayudar: Como marcar la media en un grafico boxplot ?? Por lo que veo, los boxplot en R marcan por defecto la mediana dentro de la caja, pero necesito marcar la media y ojala sacar la mediana para que no aparezcan los dos parametros. Por lo que he leido, imagino que se puede hacer con alguna funcion de bajo nivel, pero soy

Dear List, I have worked through the examples given in the help on boxplot(). If I am reading it right, only the median is produced (as a default), which is represented by the horizontal line inside the box. What argument do I need to specify if I want to show the mean as well? Thanks, platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status

There appears to be a bug in the R xfig() driver. When I run a simple example, eg > data(InsectSprays) > boxplot(count ~ spray, data = InsectSprays, col = "lightgray") the boxplot is fine. Doing the same thing after > xfig(file='test.fig') and then opening in Xfig (ver3.2 patchlevel 2) on my Linux box produces boxplots where the boxes, although correctly shaded in,

Hello R-users and developers, Once again, I'm asking for your help. I've used "identify" to identify points in a scatter plot. However, I can't apple in the boxplot..... I need to identify the outlier's id in the boxplot. Can anyone help me? Thanks in advance, Ana Patricia Martins [[alternative HTML version deleted]]

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]]

Dear all, How can I plot the number of observations per box in a boxplot. Many thanks, Bernard --------------------------------- [[alternative HTML version deleted]]

Hi, I need to convert general numbers to percentages in R to create a boxplot for purposes of comparison. Can you please tell me how I can do that? My data is attached as a csv file. Thanks. Daniel

Hi, I was wondering if there is a ready made function or parameter for indicating the sample size in boxplots? Here's what I came up with so far: library(ISwR) data(energy) attach(energy) boxplot(expend~stature) sample.size <- tapply(expend, stature, length) sample.size <- paste("N=", sample.size, sep="") mtext(sample.size, at=1:length(unique(stature)), line=2,

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 =

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

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

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
