boxplot

问题 This question already has an answer here : Closed 7 years ago . Possible Duplicate: geom_boxplot with precomputed values I have a table where each row is a different sample and each column is the name, minimum, maximum, mean, 25th percentile, 50th percentile, 75th percentile respectively. Here is a sample. sample1 1 38 10 8 10 13 sample2 1 39 10 9 11 14 sample3 2 36 11 10 10 13 I would like to know how I can use the data in this format in order to plot boxplots since that is the data that is

问题 Ok, so I think I'm pretty close with this, but I'm getting an error when I try to construct my box plot at the end. My goal is to place letters denoting statistical relationships among the time points above each boxplot. I've seen two discussion of this on this site, and can reproduce the results from their code, but can't apply it to my dataset. Packages library(ggplot2) library(multcompView) library(plyr) Here is my data: dput(WaterConDryMass) structure(list(ChillTime = structure(c(1L, 1L,

问题 I've created a side-by-side boxplot using ggplot2. p <- ggplot(mtcars, aes(x=factor(cyl), y=mpg)) p + geom_boxplot(aes(fill=factor(cyl))) I want to annotate with min, max, 1st quartile, median and 3rd quartile in the plot. I know geom_text() can do so and may be fivenum() is useful. But I cannot figure out how exactly I can do!. These values should be displayed in my plot. 回答1: The most succinct way I can think of is to use stat_summary . I've also mapped the labels to a color aesthetic, but

问题 I would like to create boxplots of multiple variables for groups of a continuous x-variable. The boxplots should be arranged next to each other for each group of x. The data looks like this: require (ggplot2) require (plyr) library(reshape2) set.seed(1234) x <- rnorm(100) y.1 <- rnorm(100) y.2 <- rnorm(100) y.3 <- rnorm(100) y.4 <- rnorm(100) df <- as.data.frame(cbind(x,y.1,y.2,y.3,y.4)) which I then melted dfmelt <- melt(df, measure.vars=2:5) The facet_wrap as shown in this solution (

问题 I have a boxplot showing multiple boxes. I want to connect the mean for each box together with a line. The boxplot does not display the mean by default, instead the middle line only indicates the median. I tried ggplot(data, aes(x=xData, y=yData, group=g)) + geom_boxplot() + stat_summary(fun.y=mean, geom="line") This does not work. Interestingly enough, doing stat_summary(fun.y=mean, geom="point") draws the median point in each box. Why would "line" not work? Something like this but using

问题 I have X=c(20 ,18, 34, 45, 30, 51, 63, 52, 29, 36, 27, 24) With boxplot , i'm trying to plot the quantile(X,0.25) and quantile(X,0.75) but this is not realy the same lower and upper quartiles in boxplot in R boxplot(X) abline(h=quantile(X,0.25),col="red",lty=2) abline(h=quantile(X,0.75),col="red",lty=2) Do you know why? 回答1: The values of the box are called hinges and may coincide with the quartiles (as calculated by quantile(x, c(0.25, .075)) ), but are calculated differently. From ?boxplot

问题 I'm trying to make a similar plot to Fig. 2d-f in an article published on Nature this year. It's basically a half boxplot with points on the other half. Can anyone give me some hints? Thank you very much! These are my data and code which produced full boxes with points inside require(magrittr) require(tidyverse) dat <- structure(list(p1 = c(0.0854261831077604, 0.408418657218253, 0.577793646477315, 0.578028229977424, 0.48933166218204, 0.53117814324334, 0.526653494462464, 0.00687616283435221, 0

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . I had a question on how to change/customize the upper and lower limit of a notch on a boxplot created by ggplot2. I looked through the function stat_boxplot and found that ggplot calculates the notch limits with the equation median +/- 1.58 * iqr / sqrt(n). However instead of that equation I wanted to change it

问题 I have a matrix with 8 columns. For each row I'd like to a plot a single boxplot. I prefer the boxplots to be in a single plot. So the following example should produce 4 boxplots (8 values each) - all in a single image. Data example: > data[2:5,] [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [1,] 0.6 0.5 0.5357143 0.5357143 0.5357143 0.5357143 0.5357143 0.5185185 [2,] 0.5 0.5 0.5357143 2.5357143 0.5357143 0.5357143 0.5357143 0.5185185 [3,] 0.5 0.7 0.5357143 0.5357143 0.5357143 0.5357143 0.5357143 0

问题 How do you make an horizontal box-and-whiskers plot in gnuplot? Similarly to this one: Gnuplot can easily be used to produce vertical box-and-whiskers plots with the 'candlesticks' and 'whiskerbars' keywords, but I have not managed to find any example of an horizontal candlesticks/box-and-whiskers horizontal plot produced via gnuplot online.
