Hi, In the example dataset below - how can I cahnge "gray20", to "blue" # data black <- rep(c("black","red"),10) gray <- rep(c("gray10","gray20"),10) black_gray <- data.frame(black,gray) # none of this desperate things works # replace(black_gray$gray, gray=="gray20","red") #

Hello, I apologize for the post as I am certainly overlooking a simple solution to my difficulties with getting a legend to print on a survplot from the rms package. I am plotting the following: survplot(survest(fita), n.risk=T, conf='none', cex.n.risk=.85, dots=T, col='gray10', lty=2) survplot(survest(fit), n.risk=F, conf='none', add=T) survplot(survest(fitb), n.risk=F,

Hi everyone, I have a problem with adding points to scatter plots. The plot is drawn with the scatterplot() function from the car library: scatterplot(data[,2] ~ data[,1], data=data,smooth=F,reg.line=F,xlim=c(0.5,1),ylim=c(0.5,1),ylab="ML",xlab="Freq",cex.lab=1.9,cex.axis=1.8) after that, I draw one line with abline(0,1,col="gray20") which works perfectly fine.

Dear R graphics gurus, Another question about lattice graphics. This time I would like to plot means and confidence intervals by group factor in a lattice graph. I can not find any working lattice examples. Maybe a custom panel function is the answer, but that is a bit beyond me for now. The individual plots within the lattice graph could look like this: # Example with confidence intervals

Hello R usuer, The code given below superimposes a pie diagram on another plot containing some points. However, I would like to center the pie diagram on the xy location on the plot, but not on the center. is there any way to re-center pic diagram. Any suggestion or better alternative are highly appreciated. Thank you in advance for your help. Regards, Bibke library(visualFields) library(car)

Dear all, back in 2002 Martin Henry H. Stevens wrote (https://stat.ethz.ch/pipermail/r-help/2002-May/019851.html) > How do I control the text in strips?

I assume that the answer worked back then, but I've tried

I probably need to be more specific. What confuses me is not the use of substitute, but the parenthesis after the dots. It clearly works and I can make guesses as to why but it is definitely not obvious. The following function gives the same final result but I can understand what is happening. dots <- function (...) { exprs <- substitute(list(...)) as.list(exprs[-1]) } In the

Hi Tim, I have also asked a similar question a couple of months ago, and someone else did the same recently, maybe on r-devel. We received no "official" response, but Deepayan Sarkar (R Core Team member) claimed that: " There is no documented reason for this to work (AFAIK), so again, I would guess this is a side-effect of the implementation, and not a API feature you should

I'm trying to create a graph where different cells of a grid (a shapefile) will be painted with a color share scale, where the most easy way is to use gray(). Can I somehow get a vector (gradient) of colors, a vector of colors with other methods but gray()? I'm doing this until now quad_N_sp <-

Hello, I have two questions: 1. How can I get black and white graphics using the pdf() device? I have tried pdf(Name.pdf, bg="white", fg"black"), but I still get full-color graphics. 2. When using lattice, how do I change the title for each panel? By default it uses the categories of the grouping factor. I would like to modify the labels in the graphic without changing

I do not know the precise language to describe the situation. But here it is what I want to do. I need to annotate a graph that contains two or more curves with labels that contain math symbols. The label must go on top of the curve. The problem is that when I annotate the plot, I can see the curve behind the label. Here it is an example using a simple straight line. x<-c(0,1)

My apriori apologies if this is felt to be the wrong list for this issue - although it starts with R, it's a combination of programs that creates the problem. Currently we are using windows metafile format for in-text tables for reports created in Word. However, we've discovered some artifactual lines being created in our final output once the Word document is changed to PDF. The process

Hi All, When I run the following code, I cannot see the entire number. As opposed to seeing 1,000,000,000. I only see 000,000 because the rest is cut off. The cex option doesn't seem to be doing anything at all. y<-seq(1e09,5e09,1e09); plot(1:5,y,ylab='',yaxt='n' ); axis(2, at=y, labels=formatC(y,big.mark=",",format="fg"),las=2,cex=0.1); Any thoughts?

Dear R community Have just recently got back into R after a long break and have been amazed at how much it has grown, and how active the list is! Thank you so much to all those who contribute to this amazing project. My question: I am trying to calculate Mahalanobis distances for a matrix called "fgmatrix" >dim(fgmatrix) [1] 76 15 >fg.cov <- cov.wt(fgmatrix)

Hi, I hope somebody can help me with this issue: I am doing population pyramids using the barplot command, so in the left side I have male age structure and in the right side the female age structure. To plot the male age structure I put the data in negative numbers. Now, I want to change the sign in the bar plot in such way that I have no-sign numbers, both in left and right side of the graph. I

Hi all I am not a C programmer, but I am trying to understand formatC to get consistent printing of reals to a given number of significant digits. Can someone please explain this to me? These first three give what I expect on reading ?formatC: > formatC(0.0059999, digits=2,format="fg",flag="#") [1] "0.0060" > formatC(0.59999,

Hi, a couple of simple graphics questions: 1. I have a little function that makes bar plots. Now I would like to limit the Y-axis outside this function (that means after calling the barplot() command) depending on the data to be plotted . Does anyone know how to do this ??? 2. When using barplot() and limiting the yAxis, R draws the bars below the x-axis. How can I avoid this problem ??

Hi all, I'm an R newbie, I did this script to create a scatterplot using the "tree" matrix from "datasets" package: library('datasets') with(trees, { plot(Height, Volume, pch=3, xlab="Height", ylab="Volume") symbols(Height, Volume, circles=Girth/12, fg="grey", inches=FALSE, add=FALSE) } ) I'd like to use the column Named

All, I am constructing a pharmacokinetic dataset and have hit a snag. The dataset can be demonstrated in the following way: myData <- data.frame( evid = c(1, 0, 0, 0, 1, 0, 1, 1, 1, 0), time = 1:10, last.dose.time = c(1, 1, 1, 1, 5, 5, 7, 8, 9, 9) ) The evid field is an indicator variable for whether the associated observation is a dosing record (when it takes value 1) or an
