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]]

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,

Hi all, I have the following dataset, call it test.data (30 columns, and one row named "0"): ADVP ADVP AP AP CONJ CONJ CP CP DU DU INF INF MWU MWU NP NP PP PP PPRT PPRT REL REL SMN SMN SSB SSB SV1 SV1 TI TI 0 96.85 2.05 89.07 2.54 70.91 2.37 94.92 3.46 82.31 11.33 40.96 2.25 98.06 3.43 90.77 17.63 86.60 10.78 60.27 1.32 93.27 0.97 77.60

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"),

Greetings all, It would appear that some default behavior changes for barplot() have been introduced into Version 1.9.1 alpha (2004-05-30). One change is in the specification of the default 'col' argument, which is now: col: a vector of colors for the bars or bar components. By default, grey is used if height is a vector, and heat.colors(nrow(height)) if height is a matrix.

I've just uploaded gregmisc 0.8.6 to CRAN, it should show up in the package tree shortly. It contains both an enhanced barplot() [named barplot2 in my code] and an enhanced heatmap() function that I would like to see propagate to the base and mva packages respectively. I've checked the code for both functions against the code in R 1.8.1, and these functions have all of the latest

Should I be able to use axis() on a barplot? i have a data.frame, the first 3 values of which are: > c[1:3,] median mean A1 56.5 58.50000 A61 73.0 73.00000 A62 63.0 63.00000 > str(c) `data.frame': 19 obs. of 2 variables: $ median: num 56.5 73 63 161 51 55 44.5 22 54 49 ... $ mean : num 58.5 73.0 63.0 161.0 47.5 ... if I do barplot(median) and then try

To all, Recently I created a version of barplot() to include some new features as follows: 1. Plot confidence intervals for each bar: The user can pass lower (ci.l) and upper (ci.u) bounds in the same vector/matrix format as "height". The CI boundary lines will vary in width per bar, if a varying "width" argument is specified. CI line width, type and color can be

Hello there, I have a question regarding bar plots. I am trying to plot the data from the following matrix as a barplot - # input data mdat <- matrix(c(0.1,0.9,0.9,0.1,0.5,0.5,0.45,1-0.45,0.6,0.4,0.8,0.2), nrow = 6, ncol=2, byrow=TRUE, + dimnames = list(c("Mon", "Mon", "Tues", "Tues", "Thurs", "Friday"), +

Hello, I've been looking through ?phantom and ?expression and this forum for examples of how I might be able to manipulate some of the names that appear on the y-axis of the barplot below. For example, the "gw" in "ECgw" would appear as a subscript...or "qr" would be the theta symbol followed by subscript "r". My attempts haven't even come close

Hi all Can anybody help me with this? I am trying to include in an automatic way the argument in arg.names in a barplot. I generate the labels I want to appear below the bars with a for loop, and they contain subscripts, so I need to use expression anch<-0.05 esp<-4 for (i in 1:dim(Ntot)[1]) { naux<-Ntot[i,] naux2<-naux[naux>0] nind<-which(naux>0)

I've used barplot(), including the anmes.arg parameter, on data frames successfully, but I'm even newer to using zoo than I am to R. :-} I am working on a functon that accepts a data frame ("df") as its primary argument, extracts information from it to create a zoo, then generates a plot based on that. The data frame has a column called "time" which is a standard

How can i set a rotation for the names.arg in barplot?

Hello! Does anyone know of a handy way to wrap the names.arg text in a barplot? I'm creating a bar plot with rather long labels; I can adjust the margins, but I'd also like to have the text wrap to about 4cm. Thanks! Kyle H.

Hello everyone, i am currently creating a barplot. This barplot takes a vector of ~200 datapoints. Each datapoint represents one bar. http://img96.imageshack.us/i/human1w.png/ (Ok as you see, it is not only one barplot, but a series of barplots). Now, these barplots represent a human chromosome. This means they are ordered. For instance bar number 50, means position 50 in the human chromosome.

'barplot' doesn't seem to work with vcd library. Am I supposed to detach vcd when I want to use barplot? Here's an example. Say I have the following matrix, > m <- matrix(c(1,2,3, 4,5,6, 3,4,5, 2,3,4), ncol=4) > m [,1] [,2] [,3] [,4] [1,] 1 4 3 2 [2,] 2 5 4 3 [3,] 3 6 5 4 Then > barplot(m) gives a barplot of the data. However,
