similar to: barplot with varaible-width bars

I'm using barplot2 to plot some data. Is there any way to determine the width of the bars in the generated plot? I know that barplot2 returns a list of the coordinates of the center of each bar, but since there is some white space between each bar, I don't know how to get the width of each bar. Jamie

Dear r-help mailing list, this seems stupid, but I actually don't find the solution: if I have a vector of numbers x of length n, ranging, say, from -3 to 4, if I do barplot (x) all the values below 0 go downwards, and all the positive values go upward. How can I make them all begin from the minimum pointing upwards? Thanks! Gabriele Zoppoli, MD Ph.D. Fellow, Experimental and Clinical

I need to increase the width of the border in a barplot, i checked both barplot, and barplot2, but cant find how to do it. how can I do? thank you john [[alternative HTML version deleted]]

Hello, I have simulated 30 observations from a binomial(5,0.1) distribution. Now I need to make frequency table( that means I need to tally how many 0's , 1's 2's....... 5's) I know that the simple R function table() will do this, but I am afraid that some times I may get zero frequency for some particular values (for example in the above there are 5-0's 10-1's ,

Dear R-users, apologies for the total beginner's question, but I have been trying to solve this problem for ages and I seem to be getting nowhere. I also have tried to search through the archives of the R mailing list, but I am still left with my problem. How do I change the width of the bars for this simple barplot? I understand that the the "width" argument might do what I want

Greetings guRus -- If a variable, e.g., 'varname', is a character string, e.g. varname <- "datavector", and I want to apply a function, such as table(), to datavector, what syntax or method will do so using only the variable varname? This seems similar to indirect addressing, but I have not seen a method for it in the R manuals. Is there a general name for such indirect

Is it possible? I was hoping to find something like: lwd for the different bars in the barplot but couldn't find it. Does it exist ?

Dear all, I am trying the barplot command but some of the labels are disappearing as there is not enough place on the graph to put them all. Here is an example of code that doesn't show all the labels: barplot(sort(runif(9,0,0.2),decreasing=TRUE),xlim=c(0,20),width=2,names.arg=c("first name","second name","third name","fourth name","fifth

Hello, I try to make barplots with rather wide labels. A simplified example of this: x <- c(12, 33, 56, 67, 15, 66) names(x) <- c('Richard with a long surname','Minnie with a long name,'Albert','Helen','Joe','Kingston') barplot(x, las = 2) Now the label 'Richard with a long surname' is too long to fit beneath the bars. A simple solution

Can I create a barchart in lattice with clusters of adjacent bars, which is possible with barplot() when beside=TRUE? How can I accomplish the grouping in lattice that is done with inputting a matrix to barplot()?

Is there any way to control the spacing between bars in a histogram, or change the border width (I'm assuming the hist() function, though alternatives are welcome)? I'm interested in changing the visual spacing between columns in a plotted histogram. The general effect I'm looking for can be accomplished in barplots using the "width=" parameter, but I have not been able

Hi again, Thanks Ted and Marc its works. But of course after pulling in in some real life data I discoverd one hitch. Often there are missing intervals. For example: from <- c(0, 1.2, 4.0, 4.2, 5.0, 25.0, 30.1, 45) to <- c(1.2, 4.0, 4.2, 5.0, 25, 30.1, 36.2, 50) intensity <- c(0, 1, 3, 2, 1, 0, 2, 5) barplot(intensity, width = -(to - from), space = 0, horiz = TRUE, ylim =

Dear R users I am modifying a column chart which I have created in R using barplot to make it clearer. I have been able to change the settings to increase the width of the axes lines and the text size but I cannot find the code to change the width of the lines which create the bars/columns themselves. Can anyone point me in the right direction please? Many thanks Claire -- View this message in

hi R-users: I want to draw three plot into one figure by layout and the script has been shown below. But I find R does not show the xlab and ylab information completely as shown the figure attached. How can I midify the script.? thank you . xxlab<-paste(cpmd," (",ro,"%)",sep=" ") yylab<-paste(rfmd," (",co,"%)",sep=" ")

I have the following in my functional test file. class UserControllerTest < ActionController::TestCase fixtures :users def setup @controller = UserController.new @request = ActionController::TestRequest.new @response = ActionController::TestResponse.new @invalid_user = user(:invalid_user) @valid_user = users(:valid_user) end def test_login_success

I'm trying to create a barplot that has two sets of data next to each other. I'm using barplot with the add=TRUE option, but this simply adds the second dataset on top of the first, obscuring it. How do I add the new data to the right on the existing barplot so that both sets are visible? I've been playing with all sorts of option and reading the list archives with no

If I have two models that are in a one-to-one relationship in Ruby on Rails, and I wish to delete a record. How do I make sure I will delete all the related data from both tables? Is there a simple elegant Ruby way to do this?

hi, I have a barplot with six clusters of four bars each. Now I would like to add the exact value of each bar as a number above the bar. I hoped to get some tips here. I could simply add text at the different positions, but I don't understand how the margins on the x-axis are calculated (how can I get / calculate the x-ticks of a barplot?). Also I would like to code this flexible enough so

Hi, I couldn't find how to have the values written on the top of each bar in a barplot. When using hist(), it is possible to use labels=T, but this option does not seem to exist for barplot(). Is there a trick I could use to do that ? Thanks to all Luc

Hi, I need bars' values on barplot, and I don't know how I can put it. I do my barplot as: data<-read.table("/my_path/file.dat",header=T, sep="\t") barplot(as.matrix(data),log="y",beside=TRUE,main="my_title", xlab="x name", ylab="y name"). How can I add the values on each bar? Thanks.. [[alternative HTML version deleted]]
