Hi, I was trying to get a list of S3 method for a given generic, along with the package in which they are defined, and I came across what looks like an issue in the data.frame returned in attribute 'info'. The column 'from' mostly gets the value "registered S3method for ..." except for visible methods. Is this the expected behavior? See code and output below. Thank you.

Dear List, This may be related to this email thread initiated by Ben Bolker last month: https://stat.ethz.ch/pipermail/r-devel/2011-July/061630.html In answering this Question on StackOverflow http://stackoverflow.com/q/7195628/429846 I noticed that `methods()` was not listing some S3 methods for `plot()` provided by the mgcv package. At the time I wanted to check the development version of R as

Hi! How to find out which plot function is used when i call plot(hist.default(1:10,plot=F)) and all works fine ? The reason why I would like to know it is that after loading some self written R functions > plot(hist.default(1:10,plot=F)) Error in xy.coords(x, y, xlabel, ylabel, log) : x and y lengths differ > traceback() 5: stop("x and y lengths differ") 4: xy.coords(x, y,

With the recent changes in R 1.9.x, it is now impossible to properly call plot on a formula() where the formula is provided via a named first argument. On today's R-1.9.1-alpha: > x <- 1:10 > y <- rnorm(x,0.25) > > plot(x~y) > > plot(x=x~y) Error in terms.formula(formula, data = data) : argument is not a valid model > > plot(formula=x~y) Error in

What is plot.new? and how can i get it to work so i can load other data? > library(splancs) > area = 6*4 > lambda = 1.5 > N = rpois(1,lambda*area) > u = runif(N,-2,4) > v = runif(N,0,4) > plot(u,v,asp=1) > h = chull(u,v) > h = c(h,h[1]) > plot(u[h],v[h],"1",asp=1) Error in plot.xy(xy, type, ...) : invalid plot type '1' >

Dear R folks, currently the section Examples contains the following as an example on how to plot a ?normal? function. plot(sin, -pi, 2*pi) Since it does not contain the argument for the function it would be helpful to add for example the following. ## plots the graph of f(x) = x**2 with f(x) ? [1, 10] curve(x**2, 1, 10) ## plots the graph of f(x) = x**3 with f(x) ? [1, 10] and adds it to an already existing plot curve(x**3, 1, 10, add=T) ## plots the graph of f(x) = x**4 connected by...

Hello, I am puzzled by the behavior of hist() when generating multiple plots per page on the pdf device. In the following example two pdf files are generated. The first results in 4 plots on one pdf page as expected. However, the second, which swaps one of the plot() calls for hist(), results in a 4 page pdf with one plot per page. How might I get the histogram wi...

Dear R users, I create a graphic with two plots side by side using layout(), like this: layout(matrix(c(1,2),1)) plot(1:10,main="left plot") lines(c(3:7,7:3),col="red") plot(10:1,main="right plot") The lines() obivously get added to the "left plot" plot. Now, I'm trying to write a function that buil...

Today's R-devel has a problem in `example(medpolish)'. It appears that the `plot.medpolish' method is not available. Here is the output and traceback() after starting `R --vanilla': > library(eda) > example(medpolish) mdplsh> deaths <- rbind(c(14, 15, 14), c(7, 4, 7), c(8, 2, 10), c(15, 9, 10), c(0, 2, 0)) mdplsh> dimnames(deaths) <-

How can I add an overall plot title to these four plots? I would like to have something that says, "Distribution Comparisons": par(mfrow = c(2, 2)) # Plot 1 plot(rnorm(10),type="l",col="red") title(main = list(paste("Normal"), ????????????????????????? col="black", cex = 1.0)) # Plot 2 plot(rpois(1...

...ing to graph, but a way to reproduce the error I observed. Plotting without the sin() did not reproduce the error. I realize this might be unique to my system, but I thought I would report the problem and see if anyone else had encountered this difficulty. I have also tried a variety of other plots and those results are summarized below. Other plot() attempts: R version 2.0.0 > plot(x=c(1:100),y=c(1:100), type="l") > plot(x=c(1:100),y=sin(c(1:100)), type="l") > plot(x=c(1:1000),y=sin(c(1:1000)), type="l") > plot(x=c(1:10000),y=sin(c(1:10000)), type...

...is hook can be used to create a new plot " The name of the hook is not very important -- I've suggested "plot.prenew" here. Another possibility could be "plot.new0". More detail on the reason: In a tabbed graphics widget (https://r-forge.r-project.org/projects/tabbedplots/ ), having this hook would enable it to operate in a mode where a new tab is automatically created for each new plot. thanks for your consideration, Tony Plate

I am trying to get a function written in R that calls a cascade of functions from the graphics package, and I want to eventually call replacements to functions in the graphics package instead of the originals. Specifically, I have a function that calls qqnorm in stats, which calls qqnorm.default in stats, which calls plot in graphics, which calls plot.default and plot.new, and I want my own

Dear All, I am trying to plot four diagnostic plots for my lm in one window. Here is some random data for an example: a = rnorm(20, mean=2, sd=0.2) b = rnorm(20, mean=1, sd=0.4) model=lm(a~b) When I set the page as: par(mfrow=c(1,1), oma=c(1,0,2,0)) and plot my model: plot(model) above all four plots the formula lm(a~b) is printed. Wh...

Hi, I'm trying to plot something in the following way and would like if you could help: I'd like in a same plot window, two plots are shown, the left one is a bird-view plot of the whole data, the right half keep changing, i.e., different plots will be shown up on request, so that when I select/click on some where in the left plot, the right plot will be the corresponding plot. What I did is: par(mfrow=c(1,2)) plot(x, y) w...

Hi, Suppose I already have two plots on the same screen, and I want to draw lines in each of them. Is that possible in R? It seems that once you have two plots on the screen, you can only draw lines in the the last plot, never the 1st. Here is what I mean: #some data y1=rnorm(1:3) y2=rnorm(1:3) #draw two plots on the same screen par...

Dear colleagues, I wish to create a figure with 6 plots arranged vertically with no spacing between them as they all have a common x-axis. However, using the code below I'm unable to get the plot area the same size for each plot. The bottom plot with the x-axis label is smaller than the others, as is the top plot which has larger margins. How...
