i wanna compare functions to be simple , let's say i want x^2 and x^5 in same plot ( it's not the case but if i get it i'll understand for others ) how i do it? x<-seq(-10, 10, l=100) > plot(x^2) and? tks [[alternative HTML version deleted]]

i calculated the density and wanna do something like this separate in 0-19-29-39-49-59-69-79-99 and put in these spaces 8 densities .. 0.something i have the frequency in % and divided already in 20 or 10 to get the density i tried and tried..made breaks vector to separate but couldn't put the other vector with the frequency density onit directly anyone know how to do it?? tks

Hello, does somebody know in a boxplot, what does each element in the boxplot represent? 1. lines at the extremes of the dotted lines? 2. Extremes of the boxes 3. Black line in the middle of the box? 4. notches? Thank you Felipe Parra [[alternative HTML version deleted]]

Dear R users, I have a matrix "final" which looks like this: final oSO4 oNO3 mSO4 mNO3 [1,] 3.3728 0.2110 1.9517421 1.01883602 [2,] 0.8249 0.0697 1.5970292 0.11368781 [3,] 0.2636 0.1004 0.6012445 0.24356332 [4,] 8.0072 0.3443 6.1016998 3.63207149 [5,] 13.5079 0.6593 12.4011068 1.55323386 [6,] 6.1293 0.1989 5.7620926 0.12884845 [7,] 0.6004 0.0661

Dear list, How can I add the mean and standard deviation to each of the boxplots using the example provided in the boxplot function? 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",

Hi, ggplot/qplot is great - it has really helped me do some nice things. However, simple boxplot of different columns/variables is a bit tricky, because of (i think) qplot's generic Y conditional on X input form. Se below. # Some data: a <- rnorm(100) b <- rnorm(100,1,2) c <- rnorm(100,2,0.5) # normal boxplot of a,b,c boxplot(a,b,c) # Looks good library(ggplot2) # loads qqplot2 #

Buenas. Alguien sabe como representar juntos , de forma fácil, los boxplot de todas las columnas de un data.frame. A mí lo único que se me ha ocurrido es unir las columnas en un vector numérico y crear un factor que me diga a que columna pertenece cada uno . ¿hay alguna forma más fácil? indice <- rep(1:ncol(datos),each=nrow(datos)) indice <- factor(indice) levels(indice) <-

Hi all, I have a question regarding the boxplot function. The data I am working on has 1 grouping variable (G) and it has many numerical variables (V1, V2, V3, V4, Vx, etc). What I would like to do is create a boxplot where the Y-axis represents the numerical values of variable V1...Vx (all the variables have the same range). The X-axis needs to represent the G-V combination. So suppose the

Dear all, I am trying to make boxplots in one diagram but it is not working. Actually I have a large dataset, around 35 water quality variables with different units and of course in different ranges (some are orders of magnitude bigger than others). I want to produce one diagram with all the boxplots of the variables of my dataset. I tried these series of commands: >oldpar <-

Thanks to David and Jorge - both of your helpful suggestions got me to the desired endpoint. In case anyone else has this question: I boxplotted my y variable data, but did the "cut" operation on the x variable in order to conserve the order of the y data. I see another suggestion coming in from another user that basically says this. So, my working line of code was: boxplot(count$RPKM

Hi, I am a complete newcomer to R and although I can plot standard box-plots I am struggling with this... I have two treatments - A & B, and 2 variables 1 & 2. I want to compare boxplots of variable 1 with variable 2 for each treatment. I would also like them to all be on the same graphic. I would like treatment to be on the x axis (A and B) and above A and B have their corresponding

Hi there, assume that you have data with different sampling like d1 <- rnorm(100) d2 <- rnorm(150) now, I'd like to create two boxplots in one graph but each plot located at the sampling number at the x-axis. This, I can do with "at" l <- list(d1,d2) boxplot(l, at=c(length(d1), length(d2)), xlim=c(0,200) ) but both plots are very thin and I'd like to increase the

I want the levels to appear in the boxplot instead of 1 and 2. What do I need to do for that? Here is the dummy code. x<-runif(100,50,80) x1<-runif(100,70,80) True.positives<-c(x,x1) splice<-factor(c(rep("Human.AA.200",100),rep("Human.AA.100",100))) splice<-factor(splice,levels=c("Human.AA.200","Human.AA.100"))

Hello: If anyone could guide me with this I would greatly appreciate it. Thanking you in advance for your assistance. Using a 3-level input factor alternative so that a function(below) can compute both a two-sided and one-sided p-values. Making the two-sided test the default. And produce output information about which alternative was tested. Where would I place the ifelse statement?

Hi everybody! I'm trying to write a script to plot a histogram, a boxplot and a qq-plot (under Windows XP, R2.10 if it matters) What I want to do: define the variables (x and y) to be used at the very beginning, so that I don't have to change all occurrences in the script when I want to plot a different variable. The dataset is called "ssfa". TO_POS is a categorical

my dataset looked like this in the beginning: >Daten V1 V2 V3 1 Dosis Gewicht Geschlecht 2 0 6.62 m 3 0 6.65 m 4 0 5.78 m 5 0 5.63 m I need box plots for V2 with all combination of V1 and V3, so I deleted the first row, and tried this: boxplot(Daten$V2[Daten$V3=="m"]) but it does not work and I

Dear R users, in the example below the name of the genus will be displayed in the main titles using the variable predictor[i] and paste. I would like to have the genus name in italic. However all my attempts using expression and substitute failed. Does anybody know a solution? Thanks a lot in advance. bernd Acrobeles <-c(65.1,0.0,0.0,0.0,0.0,0.0) Acrobeloides

Dear All, I am new to R. I amazed by this software. I have a question regarding boxplot. I have three columns say X, Y,ID (X is time from 0 to 12 hrs, Y is a variable dependent on X) I can plot a simple boxplot if it is just one group. But I have 10 groups and I want to plot all of them in one graphs. Something like multiple boxplots in one graph. I am not in R mailing list please reply to me

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")).
