Hi all, I would like to do a barplot of a dataframe like this one: alfa beta gamma delta qwert 56.5 58.5 56.5 58.5 asdfg 73.0 73.0 43.0 73.0 zxcvb 63.0 63.0 43.0 63.0 yuiop 63.0 63.0 43.0 63.0 with the labels of the rows and columns. I would like to have something that works for dataframes with varying dimensions, and so far I haven't found any way to do it.

Hi all, I am trying to filter the element of a df that start with "TF", like this: alfa = c(123221,"TF13124",41243,"TF1234",32414,"TF13124","TF14333",2134123,"TF1234") beta =

Hi all, I'm trying to process all files with a certain extension "*.ext" in a directory like this: > R --slave --args /my/dir < dir_plot.r where I then I want to do something like: myarg <- commandArgs() inputdir <- myarg[length(myarg)] print(inputdir) "for file with extension "*.ext in inputdir" do data = process.data(file) outfile =

I am trying to have llvm and clang on a centOS 5 without root permissions. I tried to do it downloading llvm and clang src packages and trying the ususal configure, make and make install steps as such: wget http://llvm.org/releases/3.3/llvm-3.3.src.tar.gz wget http://llvm.org/releases/3.3/cfe-3.3.src.tar.gz tar xzf llvm-3.3.src.tar.gz && cd llvm-3.3.src/tools/ && tar xzf

I'm sure this general sort of question has been asked many times before - I would _like_ automatic and sensible legend placement in barplots so data is not overwritten... but since there doesn't seem to be one, one of the following would be useful: One approach for this would be to place the legend to the right of the graph, and rotate it by 90 degrees. Is there a sensible way to do

Hi all, I'm trying to superimpose a rchisq density line over a histogram with something like: hist(alnlength) lines(density(rchisq(length(alnlength), 4)),col="red") But the rchisq line won't appear anywhere, Anyone knows what I am missing here? Thanks in advance, Albert.

Hi, I've got a csv file with scores like this: 40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,32,38,40,20,40,26,40,30,40,5,5,13,12,40,40,3,33,29,23,2,24,9,15,4,21,16,5,26,8,8,18 40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,32,40,40,30,40,40,37,34,40,36,13,40,13,40,5,40,8,29,5,15,34,5,22,14,20

Hi, I've got a dataframe like this: df = data.frame(a=rnorm(100,1),b=rnorm(100,10),c=rnorm(100,100),d=rnorm(100,-100)) and I want to calculate sd1 for (a,b,c) for each entry, and sd2 for (b,c,d) for each entry. I don't seem to find the answer using aggregate or apply, How can I do this? Thanks in advance, Cheers, Albert.

Hi, (I googled for this answer but didn't find anything) I am using density plot and I want to trim the ends of the line. eg: i = rnorm(100,100,2) j = subset(i,i<102 & i>98) summary(j) plot(density(j)) I only want the line to go from 98 to 102. How can I limit the line (and the axis) to the values I specify? Cheers, Albert.

Full_Name: Ximing Zhao Version: R 1.7.1 OS: MacOs X Submission from: (NULL) (64.136.27.51) When I used function plot in R 1.7.1, I found two bugs. My whole function is this: ***************** drawexp<-function(X,x,c,b){ exp<-function28(X,x,c,b) if(max(exp)>=max(dexp(x,rate=1))){ plot(x,exp, type="l",main= paste("Exponential ,n=",length(X),"

Full_Name: Fran Rizzardi Version: 0.90.0 OS: Solaris, NT 4.0 Submission from: (NULL) (128.32.135.223) If you use the horiz= option with hist() you get the message: Warning: parameter "horiz" couldn't be set in high-level plot() function. and the plot comes out vertical. The documentation says this option comes from barplot() and it does work correctly in barplot(). This

Hi, I've got a list of ~20000 elements that look like this: [1] "A00096:A00096:A00096:A00096:A02178:A02178:A07776" [2] "A00046:A00076:A01101:A04146:A05671:A07169" [3] "A00038:A00932:A02185:A02370:A02818:A02818:A02818:A02818:A04732:A07142:A07142" [4] "A00096:A01352:A01352:A02023:A05001:A05001:A07776" [5]

R Version 2.2.0 Platform: Windows When I use barplot but select a ylim value greater than zero, the graph is distorted. The bars extend below the bottom of the graph. For instance the command produces a problematic graph. barplot(c(200,300,250,350),ylim=c(150,400)) Any help would be appreciated. Paul [[alternative HTML version deleted]]

Dear R-users, I am using R version 2.10.1 under windows. In a barplot, I want to mark one of the bars with a special border color. For example: barplot(c(3, 7, 11), border = c(NA, "red", NA)) But how to do this when the bars are stacked? for example: barplot(matrix(1:6, ncol=3)) # border of second bar (i.e. the one with total height = 7) should be red again, I try: barplot(matrix(1:6,

Dear all, ## I have 4 tables like this: satu <- array(c(5,15,20,68,29,54,84,119), dim=c(2,4), dimnames=list(c("Negative", "Positive"), c("Black", "Brown", "Red", "Blond"))) dua <- array(c(50,105,30,8,29,25,84,9), dim=c(2,4), dimnames=list(c("Negative", "Positive"),

I have a problem with the ylabs in barplot. When I draw the bars horizontal the text for the y axis is not drawn horizontal too. The text remains vertical. How can I change that. Thank's for your advice. There is an example below. ##Example plot.new() jib <- data.frame(c(1:15),c(11:25),c(15:1),c(25:11)) colnames(jib) <-

Hello, I'm wondering how to set a value of mar ( par( mar=c(.......)) ) in order to allow labels to be visible in barplot. Is there any relation between the number of characters in a label and the second value of mar? Look at my example. x <- seq(20, 100, by=15) ety <- rep( "Effect on treatment group", times=length(x)) barplot(x, names.arg=ety, las=1, horiz=TRUE) Labels are

Hi All, I'm using the following code to produce some stacked bar graphs. *setwd("C:\\Users\\Tinus\\Documents\\NMMU\\R\\Seamounts")* *SChla <- read.csv("SM_Chla_data.csv")* * * *#Extract mean values from data file* * * *Coral <- SChla[185:223,] #Reduce SChla to Coral only* *coral <- with(Coral , aggregate(cbind(Pico, Nano, Micro), list(Depth),FUN=mean))*

Hi there, I am wanting to create 8 side-by-side histograms which have been rotated 90 degrees clockwise from how they usually sit.. all with the same scales. Is someone able to help me out?

Dear r-help, I am trying to plot several scatter plots with marginal histograms on one page. Ideally, a page is equally divided into 4 figure regions. Within each figure region, a scatter plot with marginal histograms will be plotted. I followed Dr. Paul Murrell's code released online to successfully plot the scatter plot with marginal histograms. The code applies "layout()" to
