R 2.15.1 OS X (MLion) Colleagues, I am aware that changes in mfrow / mfcol in par() affect cex (from help: In a layout with exactly two rows and columns the base value of ?"cex"? is reduced by a factor of 0.83: if there are three or more of either rows or columns, the reduction factor is 0.66). I generate a multipage PDF in which mfrow varies such that cex is impacted. This affect

Dear R people, I am using par(mfrow=c()) to plot multi-figures in the same window. And I like to put a common title (and xlab, ylab) for all of plots. I have already left some margin by resetting omi values in par() and hided all (xlab, ylab) for each sub-plot. Could anyone tell me how to do that? Thanks a lot, Frank

Hello, I am trying to wrap my head around the coordinates systems associated with the layout() function ...with the end goal of simply drawing a decorative line in the upper margin of my figure, which is composed of three plots. My output is defined as this: ---------------------------------------------------------------------------- postscript("out.ps", horizontal=FALSE,

I would like to use gridBase to place four separate heatmaps (actually, a stripped-down heatmap.2 from ght gregmisc package that contains only the "image" part) into four different viewports. I can get the placement correct, but I keep 'losing' the previous plot. Any suggestions? Here is some quick example code trying to put a heatmap into the left viewport and then

Dear R gurus, I am trying to plot a legend in the margins of a figure. The basic idea is to have two (or more) plots on the same figure, but then to have a common legend at the bottom of the plot. The approach that I have taken is to setup the figures, then do a "dummy" plot of the legend to determine the height of the legend box (ie from the value returned by the legend() command). I

Sorry, I have read other posts on tick marks but nothing is working. Here is my R code. I was able to turn off the x axis at one point (I removed that code), but never got the tick marks on by 20s. It always goes to the default of 50, 100, 150, 200. Thanks. R code: hist(OMY$FL, main = "2010 Oncorhynchus mykiss Fork Length Frequencies at Buck Creek Reach 1", include.lowest = TRUE, col = "blue", border = "white", breaks = 140, xlab = "Fork Length in mm", ylab = "Frequency", xlim = range(0,200), ylim = range (0,15), xba...

Dear all, I am currently trying to create a plot showing multiple single plots, for which the important issue is that the size of each plot region (not figure region!) has to be of a fixed dimension (in my case: width=1 inch, height= 0.87 inches). I tried to use "pin" to fix the plotting region to a specific size, but without success. The following example will visualize the problem:

I have been trying to draw histogram for my manscript and found some strange things that I could not figure out why. Using the same code listed below I have successfully draw histograms for a few figures with fraction labeled on Y axis less than 1 (acturally between 0 to 0.1). But one dataset gives the Y axis label 0 to 5 as fraction. This is not true, as fraction are less than 1, although the

Dear helpers, I'm using a R script on several different datasets, which makes that axis scales may vary quite a lot from dataset to dataset. So what I'm looking for now, is how to automagically find out how to position the legend (horizontal) in the space below the x-axis title, and how to make sure that the legend is within the limits of the lower inner or outer margin? I'm aware of

There seems to be something different about pdf files generated under RAqua (1.8.1). I am losing text. I am not sure when things changed but, on Carbon 1.7, when files were 'drag and dropped' onto another application they worked fine. Now the text is lost but the graphics are intact. However the text is there when viewed with Acrobat. On the other hand, if I output to an eps file and

Dear [R]-list, I am trying to do a pdf() of the following graphs but don't understand why the pdf() function does produce an empty pdf file. (I use R1.7.0 on MacOS 10.2.8) any idea? Is pdf() incompatible with screen? Thanks a lot, DLC ## create dataset x=rnorm(1000,10,2) y=rpois(1000,5) ## graphs pdf() par(col.main=4,omi=c(0,0,1.25,0)) split.screen(c(1,2))

Hello all! I am relatively new at R and was having a few issues with the following graph: barplot(c(5724.688,7290.7875), ylab=expression(paste(Delta, "AUC 45-200 min (?g/ml * 155 min)")), xlim=c(0,2), width=0.5, border="black",font.lab=2,cex.lab=1.7, names.arg=c("Saline (n=8)", "Exendin (9-39) (n=8)"), axisnames=TRUE, cex.names=1.7, ylim=c(0,9000),

Hi everyone. I'm using this following code: pdf(file="Fig5.pdf", width = 4.86, height = 6.29, pointsize = 10, family ='Times') par(mfcol = c(3,2), mai = c(0.4,0.8,0,0), omi = c(0.7, 0, 0.7, 0.1)); hist( rnorm(100) ) dev.off() When I open this in any vectorial software (like Illustrator), it says that my font size is 7 instead of 10 that I specified. I have tried

Dear all, I have a simple plot using "gridBase" like this. The problem occurs whenever I execute this code there is always a blank page created before the actual plot. How can we disable that blank page? I am using: R version 2.7.2 (2008-08-25) and gridBase version: 0.4-3 __ BEGIN__ library(grid) library(gridBase) opar <- par(no.readonly=TRUE) par(opar) grid.newpage()

Hi, what i need is as the example i attached in the box plot. As you can see, the boxplot have margins and it kind of follow the coding I've added, but, it does not happen for the heat map. Could you help me with this.. Thanks in advance. the following is the coding i've used: # Draw the heatmap # heatmap.r # # Purpose: Create a heatmap # # Input: Data matrix as

Hi all, I have read through the archives, but can't find a solution to this problem. I need the text direction on "dependent B", plotted in margin 4, to go top to bottom (opposite what it is now). Here's some sample code: #plot with mtext example par(mgp = c(2,1,0), mfrow=c(2,2), las=1, mar=c(2,2,2,2), omi= c(0.5,0.2,0,0.2)) a<-1:10 b<-7:16 c<-21:30 plot(a~b,

I am creating a CDF plot function more user-friendly than any default r function. Depending upon the bimodality of the data (it is often bimodal), or any other strange data trends, the points can end up gathering in just about any corner of the plot. So, when I add a legend, whether I choose to add it in the bottom right, top left, or wherever, it will sometimes end up putting the legend right

Hello! I want to display four xyplots in the same window (sorry if I don't use the propers words, but my English is rude) I know that if I use plot(y~x) then x=(1:100) y=(1:100) par(mfrow=c(2,2)) plot(y~x) plot(y~x) plot(y~x) plot(y~x) would give what I want, but this is not the case because I need the functions of xyplot. So I did the following: plot.new()

Dear all; I'm trying to create a 2 x 3 plot (something I know like lattice can do better) using the plot function. However; I'm not sure how to make the width of the plots to be the same on each column. I guess the answer maybe obvious but I haven't been able to figure it out. I'll appreciate any suggestion. Here is the (highly inefficient) code for the first row: par(mfrow =
