There seems to be a minor bug in barplot.default when used with log scale w= here one or more values is NA: dat <- matrix(1:25, 5) dat[2,3] <- NA barplot(dat, beside =3D T) #Plots and appropriate barplot with gaps for m= issing data barplot(dat, beside =3D T, log =3D "y") #Error in if (min(height + offset) <=3D 0) stop("log scale error: at least = one 'height +

This in an enhancement requestion, to add the capability to pass arguments through barplot() to legend(). I've created a version that does this. # Run this code; notice that the legend # is superposed over one bar: barplot(height = cbind(x = c(465,91) / 465 * 100, y = c(840,200) / 840 * 100, z = c(37,17) / 37 * 100), beside = FALSE, width =

<<insert bug report here>> barplot hardcodes xpd as "TRUE" causing the bars to go outside of the plot region. True can be the default, but it shouldn't be the only option. *** barplot.R Sat Sep 8 10:15:16 2001 --- barplot.R.orig Sat Sep 8 10:03:39 2001 *************** *** 5,11 **** legend.text = NULL, beside = FALSE, horiz = FALSE, col =

"contour" can't return a list of contours (it would be nice) "arrows" has different options from S-PLUS (no "open" or "rel" options, no "lwd" parameter or graphics parameter pass-through; "size" in S corresponds to "length" in R). [I know we needn't follow S-PLUS syntax slavishly, but it would be nice at least to

Clearly, barplot should have an `axes' argument. The following trivial patch does that ... pls apply. -k *** src/library/base/funs/barplot.orig Sat Aug 2 15:58:44 1997 --- src/library/base/funs/barplot Sat Aug 2 16:00:22 1997 *************** *** 1,7 **** "barplot" <- function (height, names.arg, col=NULL, border=par("fg"), beside=FALSE, space=0.2,

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,

Here are another three problems with logarithmic scales: 1) segments() does not work with logarithmic scales. I suggest to change lines 962-973 in "plot.c": for (i = 0; i < n; i++) { if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0])) && FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) { GP->col = INTEGER(col)[i % ncol];

Dear All, Would you please tell me how to display the sample No. on the map ? ---Below commands don't display the sample No.(from 1 to 150).--- library(som) library(klaR) iris.som3 <- som(iris[,1:4], xdim = 14,ydim = 6) library(klaR); opar<- par(xpd = NA) shardsplot(iris.som3, data.or = iris,label = TRUE) legend(3.5,14.3, col = rainbow(3), xjust =0.5, yjust = 0,legend =

R users, I have a problem with function strwidth in 2.7.1. I'm trying to set the plot margins in a way that horizontal column labels will fit to the graph. tmp.t is a list of data.frame objects. This code works well in 2.6.0. ...snip.. library(gplots) for (i in names(tmp.t)) { bmp(filename=paste(i, "_", Sys.Date(), ".bmp", sep=""), width=1038,

dear r-helpers, i have got another question: i am using the functions par(xpd=T) legend to create a legend below the x-axis. i used the parameter horiz=T. now i would like to put the elements of the legend in two rows: e.g. if my legend has got 5 elements, i would like 3 elements in one row and the last two elements in the next row. does anyone know how to do that? thank you very much for

Dear R developers, I needed to align the title of legend for some of my plots. If there is interest to include this into base R, bellow are the examples and the relevent diffs.

Please find attached a diff for coplot which you may want to consider for the next release. The diff is against R 1.2.2. The reasons for this patch are: 1. The boxes of coplot did not align very well with the panel graphs if applied to a factor 2. Putting the

Dear R users, I'm making multiple plots within the same pdf page (par(mfcol = c(5,1)), and want a legend for this at the bottom of all the plots. From previous mails it has been suggested to use par(xpd=TRUE), increase the margin at the last plot, and then draw the legend. However, when I do this, the last plot gets smaller with the same amount I increase the margin with. The problem seems to

Hola. Tengo un gráfico que tiene muchos names.arg (demasiados...), de modo tal que le vendría bien al lector usar colores intercalados, tal que el primero sea azul, el segundo negro, el tercero azul, cuarto negro, y así. Es decir, definir un vector "similar" a este: rep(c("black", "blue"), length(barras[,1]/2) que permita pintar uno y uno en este gráfico:

Core developers, I couldn't find any simple way to send a vector of colors to apply to each terminal in plot.dendrogram() or plot.hclust()---I asked R-help about it a few weeks ago and didn't get any response---so I hacked that functionality into the plot.dendrgram code (see below for hacked function plus examples).... Is there any chance this functionality could be added to the

Hello, I try to handle a simple bar-plot, but it turns out to be not as simple as I thought. 1) I have created a .dat-File, e.g. test.dat: DATA DATA-SEM 2.2 0.32 6.2 1.30 12.7 1.61 48.6 3.08 4.1 0.86 4.5 0.32 1.5 1.13 1.2 1.08 The first row is the data represented by bars. The second row deals with the Standard Error of Mean. The lines correspond to time-intervals of experiments. 2) I now

Hi everyone, I'm trying to plot density curves on the axes of a plot, in a similar way to the 'rug' function. I have had a look at a few approaches and libraries, including: * layout http://addictedtor.free.fr/graphiques/RGraphGallery.php? graph=78 * fancygraph http://addictedtor.free.fr/graphiques/RGraphGallery.php? graph=81 * ggplot - gave up since it needs R 2.3.0 and

Hello list, I'm trying to plot nls profiles, but the plot.profile.nls function in R doesn't seem to accept any plot.default variables. Specifically, I'd like to be able to change the x-axis title and the colors to black and white. Has anyone had any luck with this? If not, is there a way to override to plotting colors, perhaps in par()? Thanks, Sam fm1 <- nls(demand ~

I have a simple barplot that looks fine in the R graphics device window. However when I export it to png I am losing the x-label. It must be an obvious problem but I cannot see it. Trying to resize the plot does not seem to help. Code is below. Any help gratefully received. ###### Start Code############ Groups <-c(21.8,45, 43, 17.2, 8.3, 18) names(Groups) <- c("Exeter",

Hi, I'm using the lattice function 'barchart' to make a series of 4 histograms. Currently, the y-axis values are graphed in order of the y-axis variable. I'd like to have the y-axis values sorted in ascending order of the x-axis values so that the longest bar horizontally is on top of the graph (in it's seciton) and the shortest bar is on the bottom. I can do this in
