similar to: A question about boxplot: mean and median

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]]

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.

Hi all, what a great help list! I hope someone can help me with this puzzle... I'm trying to find a simple way to do: boxplot(obs~factor) so that the factors are ordered left-to-right along the x-axis by median, not alphabetically by factor name. Complicated ways abound, but I'm hoping for a magical one-liner that'll do the trick. Any suggestions would be treasured. Thanks,

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 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]]

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???

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

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

Hi, I just made a boxplot but I want to change the thickness of the line used for the median to look a little thinner. Could anyone please help me figuring out the R-code to do it? Thanks, I really appreciate it. Suyan

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

I am very new to R so forgive me if this seems basic but I have done extensive searching and failed to come up with the answer for myself. I am trying to label a boxplot I have created with the values for the median, upper and lower quartiles and max and min values. I have been unable to do this or find anything on the net to say how it might be done. Is this possible and if so how? Regards,

Hi, I tried to use boxplot function. I am following the ?boxplot and can change the whisker box width using lwd parameter. However, when outline=TRUE, the thickness of the circle of the outliers is not proportionally changed when I change the line width of the whisker box. There must be another parameter for that. Unfortunately I don't know. please help and thanks much in advance. --

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,

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

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

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 =
