similar to: Quasi-bug in boxplot().

I'm graphing a series of boxplots of grouped data inside a function that passes the data.frame, the names vector, and a title vector. Because both the data subset changes with each successive pass through the function, occasionally the names vector turns up with only one group to plot. This is an expected result. However, when the names argument in boxplot has only a single name, it

Was there ever a convenient method provided to add boxplots to the current plot at specified x values? There was a question by Martin Maechler some time ago here, but I could seem to find any satisfactory resolution of it. I see that there is an add=T option to boxplot and bxp, but I don't see how to set the x-values. url: http://www.econ.uiuc.edu Roger Koenker email roger at

Dear all, I am a total beginner in R, so sorry if this is the wrong place. I am using R 2.10.1 on a Mac (Mac OS 10.6.2). I have this small dataset : growth sugar 75 C 72 C 73 C 61 F 67 F 64 F 62 S 63 S I have no problem reading the table, or getting the summary, but if I try boxplot(growth~sugar, ylab="growth", xlab="sugar", data=Dataset), I have the following error :

Full_Name: Steve Ellison Version: 2.4.1 OS: Windows, Linux Submission from: (NULL) (194.73.101.157) bxp() allows specifcation of box locations with at=, but neither adjusts xlim= to fit at nor does it respect xlim provided explicitly. This is because bxp() now includes explicit xlim as c(0.5, n+0.5), without checking for explicitly supplied xlim (or ylim if horizontal). This also prevents

Dear guRus, I want to do some boxplots, but the median sould appear in another line-thickness and another color. I do not know, what to do in order to realise my wishes. Sorry for that question, but I am new to R. cheers steph -- Linux: the operating system with a CLUE...

Hola, por mi parte doy por zanjado el tema. He llegado a la causa raíz de mi problema: falta de conocimiento de la forma en la que se debe usar la ayuda de las funciones de R y gracias a vuestra colaboración, ¡ya se cómo hacerlo :) !   Nuevamente,gracias a todos. Saludos,   Fernando   -- ____________________________________   Hola,   La misma función boxplot indica la existencia de estas

v 2.0.1 (sooooh old!) on Win2k I think I know the answer to this but I can hope ... I have data for continuous variables (measures of residents) by a categorical variable in range (1,22), the units in which they live. I want to plot these data with a pair of boxplots one above another with same x-axis (1,22) using par(mfrow=c(2,1)) and then plotting first for the women then for the men.

I''d like to make the following changes (differences are from R1.0.1): boxplot.default() 1c1 < function (x, ..., range = 1.5, width = NULL, varwidth = FALSE, --- > function (x, ..., range = 1.5, width = NULL, varwidth = FALSE, boxwex=0.8, 37c37,38 < bxp(groups, width, varwidth = varwidth, notch = notch, --- > bxp(groups, width, varwidth = varwidth,

Hi, the graphical parameter "cex.axis" does not have any affect for "boxplot": data(iris) boxplot(iris[,1:4], ylab="y", cex.lab=2, cex.axis=2) The patch is simply adding "cex.axis" to the search for axis relevant parameters in "bxp": ax.pars <- pars[names(pars) %in% c("xaxt", "yaxt", "las",

Dear List, ? I am creating a boxplot with two subsets, very similar to the example by Roger Bivand at ?boxplot (reproduced below).? I am trying to change the labels on the x-axis to have one number to cover both subsets.? I can do this in other plots by using axis=FALSE followed by a separate axis() command.? I have also tried variations in the names= argument but can't get it to work.?

Dear R-core team, I think I found a small inconsistency in the boxplot function. I don't want to post it as a bug since I'm not sure this might be considered as one according to the FAQ --- and this is not a major problem. Don't hesitate to tell me if I'm wrong. If you try to do a boxplot on a matrix and set the "at" argument to some vector different from 1:n, n is the

When plotting using the cex.axis argument to boxplot(), the size of the plotting symbols beyond the whiskers of the boxplot are being changes. Example: par(mfrow=c(2,1)) boxplot(c(rnorm(10), 10), horizontal=TRUE, main="Test", las=2, cex.axis=2) boxplot(c(rnorm(10), 10), horizontal=TRUE, main="Test", las=2, cex.axis=1) This is from the following line in bxp()

Hello, I have created two boxplots with following R code. There is one outlier in B group. The outlier is 33. But the all other data are between 0 to 4. How can I skip y-axis around 5 to 25, and expand 0-4 for this case. Also I want keep the outlier in my boxplot. I want my boxplot look like the second one, keep the outlier, and make an interrupt of y-axis from 5 to 25. Thanks, Jianghong

Greetings, I am trying to add a boxplot to the bottom of a histogram, right between the histogram bars and the x axis. Here is the code I am using at the moment (the par line is probably not relevant for our discussion): hs <- hist(x, breaks = 20, plot = F) par(mar = c(3,3,2,1)) hist(x, breaks = 20, main = NULL, ylim = c(-2, max(hs$counts))) boxplot(x, horizontal = T, axes = T, add =

Hi I have two vectors of integers and I am plotting a box plot that contains both vectors. I have done the following: vec1 < -scan("file1") vec2 < -scan("file2") boxplot(vec1, vec2, range=0, horizontal=TRUE, names=c("One","Two"), boxwex=0.15) I managed to get both boxplots on the same figure but there they are wide apart. Is there a way to reduce

A student asked me if it was possible to draw boxplots where the boxes themselves were grouped: I was able to hack boxplot.formula() to do the right thing, more or less, by incorporating an argument (space) and some code from barplot. with the extended boxplot.formula() below, the following commands "do the right thing" (produce boxes grouped by levels of the second factor): r =

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

Hello there, I was wondering if anyone might be able to help me as I'm pretty new to R. I'm trying to create a boxplot from a data table returned from an sproc. I have the following code, which generates the plot as I'd like it: library("RODBC"); conn <- odbcConnect("datawarehouse"); # connect to datawarehouse results <- sqlQuery(conn, "call

Dear list, With the below codes, I got 8 bwplots but I would like to put 2 bwplots in one single graph so that instead of 8 separate bwplots I would have 4 graphs, each contains 2 bwplots. How can I do that? Another question is how do I add the mean as a point to each boxplot in the bwplot but also keeping the median line. for (i in 1:length(dat)){ windows() with(dat[[i]],

Hi! I am trying to get the tick / label under a stacked boxplot with only a single data row. With >=2 rows it works, but with a single one the tick resp. my class name is not printed below the boxplot. Can anybody point me to what am I doing wrong? For example: boxplot(data.frame(c(3,4,5)),names=list("a"),beside=F) Here, I would like to have the "a" below the single
