Hi there, I was wondering if anybody can explain to me why the boxplot ends up with different results in the following case: I have some integer data as a vector and I compare the stats of boxplot with the same data divided by a factor. I've attached a csv file with both data present (d1, d2). The factor is 34.16667. If I run the boxplot function on d1 I get the following stats:

The issue is not with boxplot, but with split. boxplot.formula() calls boxplot(split(split(mf[[response]], mf[-response]), ...), but look at what split() returns when there are empty levels in the factor: > f <- factor(gl(3, 6), levels=1:5) > y <- rnorm(f) > split(y, f) $"1" [1] 0.4832124 1.1924811 0.3657797 1.7400198 0.5577356 0.9889520 $"2" [1] -1.1296642

Hello, I was wondering if I can plot two curves I get from "density(data)" into one plot. I want to compare both. With the following commad, I just get one curve plotted: plot( density(mydata) ) Sorry for this stupid question but I could not find a solution until now... Antje

Hi, I am trying to color the data points on my boxplot but I only get the default black. Not sure why. Any ideas? Thank you, Mark Here is my code. > dat.g100 <- dat.sg[100,] # selected gene (row) from a dataframe of 37 columns > d1 <- as.matrix(dat.g100[,1:18]) # subset 1 > d2 <- as.matrix(dat.g100[,19:37]) # subset 2 # boxplots > par(mfrow=c(2,1)) > boxplot(d1,

Hi there, I get a strange behaviour of a boxplot with the following code. There seems to be a problem with the xlim-parameter. Did I do anything wrong? What else can I do to force the boxplot to have a defined x-range? x <- rnorm(100) boxplot(x, notch=TRUE, xlab=parameter, xlim <- c(-4,4), horizontal = TRUE) Antje

Dear all, I would like to have the same color for the all boxplots from the same panel, but my code below shows the two colors alternating. Thanks! set.seed(42) D1 <- rnorm(200) D2 <- factor(sample(letters[1:2],200,TRUE)) D3 <- factor(sample(letters[3:5],200,TRUE)) DF <- data.frame(x=D1,a=D2,b=D3) print(bwplot(b~x|a,data=DF,col=c("black","black"),

Hi folks, I've just discovered that the following code leads to boxplot (surprisingly to me). Can anybody explain to me why? Is this documented somewhere? I've never consider this option before. x <- rnorm(300) l <- c(rep("label1",100), rep("label2",50), rep("label3",150)) df <- data.frame(as.factor(l), x) plot(df) Thank you! Antje

Is there any way to get a boxplot of several data sets beside one another on the same graph, as there is for barplot? If I do: d1 <- data.frame(a = c(rep(1:3, each = 3)), b = c(1:9)) d2 <- data.frame(a = c(rep(1:3, each = 3)), b = c(9:1)) boxplot(d1$b ~ d1$a) boxplot(d2$b ~ d2$a, add=T) It will show the two datasets on the one graph, but the middle point will overlap. What I want is

Hi there, I'm trying to solve a boxplot problem (should be simple, but I cannot find the solution...): data <- list( "long_name1_xxxxxxxxxxx" = rnorm(100), "long_name2_yyyyyyyyyyyyyy" = rnorm(200)) boxplot(data , las = 2, mar = c(20,4,4,4)) Why does the margin not change whatever I put there??? With other plots it worked for me, why not in this case? I just want to

Hi, I want to add boxplots to a scatterplot: plot(x,y, xlim=c(80,120),ylim=c(80,120)) boxplot(y,add=TRUE,at=118) boxplot(x,add=TRUE,at=118,horizontal=TRUE) How can I control the width of the boxes (say, I'd like them to be of width 3 in the variables' scales). I've tried the "width" parameter but failed. Thanks in advance, Marcin

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

Hi everyone, I made this set of boxplots that would show me the widths of some sites broken up by some chromosome, but I don't know how to make it indicate the number of data points that created the boxplot. How do I do that? boxplot(data$site~data$chr,varwidth='TRUE') -- View this message in context: http://r.789695.n4.nabble.com/boxplot-width-tp2266805p2266805.html Sent from the

Thank you for your guys reply for my previous question. But I got one more question about the boxplot. With the code in the R-help: boxplot(len ~ dose, data = ToothGrowth, boxwex = 0.25, at = 1:3 - 0.2, subset = supp == "VC", col = "yellow", main = "Guinea Pigs' Tooth Growth", xlab = "Vitamin C dose mg", ylab =

I'm relatively new to R, and have looked through the documentation and FAQ, and have not been able to find out how I can accomplish something. If someone can point me in the right direction, I would greatly appreciate it. I am doing system performance tests, and end up with large volumes of data that consists of transaction timings, coupled with system timings. The analysis process is

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

bonjour, je voudrais savoir s'il serait possible de sugg?rer aux d?veloppeurs de R de proposer une option suppl?mentaire pour les moustaches, ? savoir les placer sur d1 et d9 comme c'est pr?conis? dans les programmes du secondaire en France, option du style boxplot (serie,range=91) par exemple... i would like to know if it is possible to have (with the agrement of developpers)

I have some code as shown below. Basically, I would like three boxplots to be set next to each other with no ylabels on the two "inner" plots, and I want the same x axis range on all three. However, it seems like boxplot does not respect the xlim setting. I've tried the various ways I thought would work (par, boxplot(...xlim=)) but none of them seem to work. I then tried plot.window,

Is there a quick way to make boxplots groups by two variables? By that I mean, that if x axes have values ("A","B","C"), than at each value there would be a few boxplots each for a value of second variable (say ("1","2","3")). Thank You. -- Vadim Kutsyy http://www.kutsyy.com vadim at kutsyy.com The University of

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 =
