boxplot

问题 I want to (got suggestion to do so) create boxplot with different look and added labels to it. The expected (not complete) output will look like the following (with every box has quatile labeles) and sample size. boxplot(len~supp*dose, data=ToothGrowth, notch=TRUE, col=(c("gold","darkgreen")), main="Tooth Growth", xlab="Suppliment and Dose", names = supp ) # some unsuccessful trials # to add names boxplot(len~supp*dose, data=ToothGrowth, notch=TRUE, col=(c("gold","darkgreen")), main="Tooth

问题 Is there a way to create a boxplot in R that will display with the box (somewhere) an "N=(sample size)"? The varwidth logical adjusts the width of the box on the basis of sample size, but that doesn't allow comparisons between different plots. FWIW, I am using the boxplot command in the following fashion, where 'f1' is a factor: boxplot(xvar ~ f1, data=frame, xlab="input values", horizontal=TRUE) 回答1: Here's some ggplot2 code. It's going to display the sample size at the sample mean, making

问题 My input table has two columns like this: x y 1 187 2 235 3 857 3 253 2 955 1 267 I want to make a boxplot of the y values for each individual x value. The x values are limited to 1, 2, 3. Here is my R code: data=read.table("input.txt") arr=array(dim=3) for (i in 1:3) { arr[i]=data[data.x==i,"y"] // This line raises warnings. } boxplot(arr) How to correct my code? 回答1: foo <- data.frame(x=rep(1:5,each=20),y=rnorm(100)) with(foo,boxplot(y~x)) 来源： https://stackoverflow.com/questions/30750049/in

问题 Per default, for the lower, middle and upper quantile in geom_boxplot the 25%-, 50%-, and 75%-quantiles are considered. These are computed from y , but can be set manually via the aesthetic arguments lower , upper , middle (providing also x , ymin and ymax and setting stat="identity" ). However, doing so, several undesirable effects occur (cf. version 1 in the example code): The argument group is ignored, so all values of a column are considered in calculations (for instance when computing

问题 Let's consider this data: df = data.frame('score'=round(runif(15, 1, 10)), 'group'=paste0("a",rep(c(1,2,3),each=5)), 'category'=rep(c("big", "big", "big", "big", "small"), 3)) I would like to plot boxplots of this data with ggplot2 . What i want is: boxplot(score~group), but with the boxplots arranged according to the mean of the "big" individuals of each group. I can't figure it out in a simple way, without creating new variables. OK to use Dplyr. Thanks. 回答1: I don't know if this qualifies

问题 Following up on this question and for the sake of completeness, I modified the accepted answer and customized the resulting plot, but I am still facing some important problems. To sum up, I am doing boxplots reflecting significance of Kruskal-Wallis and pairwise Wilcoxon test comparisons. I want to replace the p-value numbers with asterisks, and show only the significant comparisons, reducing vertical spacing to the max. Basically I want to do this, but with the added problem of facets, that

问题 I want to plot Delta~Project.Types in R. I have 10 Project Types. I know how to do the boxplot : boxplot(Delta~Project.Types). However, how can I put the fivenum (min, max, 1st, 2nd, and 3rd quantile) on each boxplot? How can I do for that every boxplot of the image will have its five number shown? That would be easier to compare the boxplots when the values are shown Thanks! 回答1: The stats you want can also be obtained with fivenum five <- by(InsectSprays$count, InsectSprays$spray, fivenum)

问题 I have a dataframe with a column of categorical data (two possible values) and multiple variable columns. I need to plot multiple box-plots, one for each variable column. Each plot compares the value of the variable between the two categorical groups given in column 1. So far I have it working by writing an individual plot call for each column. #CREATE DATASET mydata <- data.frame(matrix(rlnorm(30*10,meanlog=0,sdlog=1), nrow=30)) colnames(mydata) <- c("categ", "var1","var2", "var3","var4",
