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 R-community, using R.2.9.1, how do you put reference lines or grids into the _background_ of a plot? For example: barplot(3:1) abline(h = seq(0.5, 2.5 ,0.5), col = "red", lty = "dashed") -> The lines are before the bars (and the line parts going through the bars might be considered as "chart junk", I suppose). Now, in this toy example I could just do the

Hi all, I'm plotting a histogram of dates and would like to shade the bars, e.g. hist(.leap.seconds,"years",col='gray',freq=T) -but the axis color also changes, how do I prevent that? thx in advance Janus [[alternative HTML version deleted]]

Hello R Fundi, The poetic title of this post is a request for help in regard to a "simple" plotting question. I have displayed the mean observations of a series variables using barplot(). On the same figure I have colored the bars to represent the Standard deviation of each variable using color.scale(). Now I wish to add a graduated colorbar (legend) that corresponds to the colors

I've made a barplot that has several bars. I'd like the bars to be colored according to the type of category they are in. Is there a way to put a conditional into the color parameter in barplot? i.e. if data$category[i] == 1, color the bar red Do I need to generate the coloring sequence before the plot code first? Thanks!! -- View this message in context:

Hi all, I want to represent two categories with one color and have other categories a different color on a bar plot. I can do this using for one category/number using the ifelse call in col but how to extend to two categories/numbers? barplot(dataframe$vector_o_numbers, col=ifelse(dataframe$vector_o_numbers == 00, "red", "black"), names.arg=dataframe$labels) For example if

Hi, In barplot(height, col = ...), the col = vector recycles so that the same colors are used for each bar. I would like to use different colors in different bars (corresponding to another piece of information, here, the region of the country being represented). For example, x = matrix(c(5,2,3,1),nrow=2) barplot(x,col=1:4) will draw two bars with two segments each, but each colored red and

Hi, I'm trying to construct a legend which has four lines of text and associated symbols. The first two symbols need to be normal lines which vary only in colour. The second two symbols should have filled boxes. How do I suppress the fill boxes in the first two lines? J.

Hello! In a grouped Dotplot, is there any way to set the color of error bars to be the same as the corresponding symbols? Example data: require(lattice) require(Hmisc) data(barley) Dotplot(variety~Cbind(yield, yield+2, yield-2)|year, groups=site, data=barley) I experimented with changing trellis settings of plot.line (as mentioned in the Hmisc documentation) as well as col.line settings in

Hi, I am plotting a distribution of (ordered) values as a barplot. I would like to label groups of bars together to highlight aspects of the distribution. The label for the group should be the range of values in those bars. As this is hard to describe, here is an example; x <- rlnorm(50)*2 barplot(sort(x,decreasing=T)) y <- quantile(x, seq(0, 1, 0.2)) y plot(diff(y)) That last

Hi, because wine 1.0 rc3 isn't available via yum (I'm using Fedora 9 btw.) I've installed it via Source-Code. In this case I downloaded it, run ./configure --verbose, followed by make depend, make and make install. It's installed and seems to run, but there is no entry in Applications. Have I forgotten to install something for that? best regarts Heinrich

Dear R-helpers, (1) I can't figure out how to tell Dotplot that I want the colors of the CI bars to be the same as the colors of the dots. For example: t2a.ci3 <- data.frame(est = c(7, 20, 75), lower = c(-9, 0.5, 42), upper = c(22, 39, 109)) mypal <- c('skyblue3', 'mistyrose3') condNames <- c('noise', 'horn', 'marimba') Dotplot(1:2 ~

Hello, we frequently face locking issues with office applications and documents on samba shares. The office applications claim that the document is locked and hence no write access is possible. I can check on the samba server that there is no concurrent access/locking from other computers or users. It looks like the same user holds some lock and is denied to access the document because it?s

Hello, a probably rather stupid question to which I can't find an answer: I have a bar chart, and I want to present which bars are significantly different by placing a line with an asterisk above then (similarly to fig. 3 in: http://jnm.snmjournals.org/content/46/4/574.figures-only). Does anyone have a reference where can I find some instructions how to learn this? Thanks a lot! Omer --

Hello, I have a bar plot where I am already using colour to distinguish one set of samples from another. I would also like to highlight a few of these bars as ones that should be looked at in detail. I was thinking of using hatching, but I can't work out how or if you can have a background colour and hatching which is different between bars. Any suggestions on how I should do this? Thanks

Hi list, # net join asks for the root password (seems to be new). This is not a problem, but when i do: # ssh root@remote_host net join mydomain the root password is echoed on the terminal. Is this expected behaviour? (I hope not).

Hello, I am working with R version 2.10.1 under windows. In a text file, I need to replace all characters at certain column positions with blanks. For example, say the file contains two lines and looks like this: ab34cd78e fg3 hi78j I'd like to replace everything at positions 3-4 and 7-8 with blanks, so the output should be: ab cd e fg hi j [I'm not sure if this is really an R

I am trying to add 2 stdev error bars to lattice type plots: panel.ebar<-function(x,y,dy=NULL,...) { panel.xyplot(x,y,...) panel.segments(x,y-dy,x,y+dy,...) } Then: xyplot(y~x|fc,data=dat,dy=dat$dy,panel=panel.ebar) This adds error bars but they are not conditioned on the factor fc. xyplot(y+I(y-dy)+I(y+dy)~x|fc,data=dat) This produces 3 series of points in different colors, conditioned

Hello everyone, I'm evaluating the Celt in terms of robustness against bit errors. So what I have done is encoding a wav file using the \tools\celtenc.exe and then manipulated the wav file according a desired bit error rate or burst error length. But the Celt decoder stops decoding with the first bit I manipulated even if this bit is not in the header. So is there a way to do the test
