Hi R collective, I quite like the "curve" function because you can chuck a R function into it, and see the graph in one line of R. I had a google and found some threads for filling under the line; http://tolstoy.newcastle.edu.au/R/e2/help/07/09/25457.html However they seem to miss the point of the simplicity of going, "I wonder what that looks like, and can I have some colour

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Symptoms: curve with log x axis gets the wrong x limits (in 2.6.1, I believe introduced in this version). Credit goes to Mike McCoy for detecting the problem. Demonstration: x = 1:5 plot(x,5*exp(-x),xlim=c(0.1,1000),log="x") xvec = 10^seq(-1,3,length=100) lines(xvec,5*exp(-xvec)) curve(5*exp(-x),add=TRUE,col=2,lwd=3) I believe

I am sure it is just me not understanding how R works, but could somebody explain why curve(cos(x)) works and curve(expression(cos(x)) does not? I have done some investigating and here is what I found. If I comment out the line of curve indicated below, both calls work fine. function (expr, from, to, n = 101, add = FALSE, type = "l", ylab = NULL, log = NULL, xlim =

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];

Hi again, another problem: This (below) isn't working and as far as I can see it damn well should. What I'm trying to acomplish is to run several data sets through the same graphing procedure, but for the pH data use a log y axis. using this code all graphs are drawn with a linear axis. Surely I should be able to set the ylog option to T using another object (logaxis). for (n in

1) 'par' doesn't seem to be called from 'plot', as it is in S. I was able to get the plot to work with: par(mar=c(5,5,5,5)) plot(a,b) axis(4,labels=F,tck=0.1) mtext("blabla",side=4,line=3,cex=1.5) NOTE: I tried this on the x11() display, which seemed to reproduce the problem you described. 2) ?? I was unable to get either x or y logarithmic axes using

This problem has been mentioned by Arne Kovac <maak@stats.bris.ac.uk> on May 9-10. The patch is really a replacement of 'axis' in RHOME/src/library/base/funs/ It contains the fixes which where proposed Arne Kovac and fixes (all?) the errors he/she (?) reported on May 9. "axis" <- function (which, at, labels = TRUE, ...) { if (which%%2 == 1) { axp <-

Hi All, I have been able to modify the x-axis to start at zero by adding xlow and xhigh parameters; that was pretty simple. I have been unable to find the location of the code that would turn off the information weighting of the box size (I have smaller randomized trials getting less weight than a much larger non-randomized trial). The function is forestplot() from rmeta. Thanks for any

Here's a number of items that came up in connection with my course for medical ph.d. students this week: boxplot(): - deals ungracefully with empty groups and factor levels not present in grouping variable. - no indication of what variable is being plotted data.entry() (mostly W95 rseptbeta problems) - Entry of first variable name doesn't take before 2nd

I hope it's OK to post a bug report, and a possible patch, on this list. Introduction ======= The split.screen() docs suggest that users should not return to a screen after it has been drawn, and that curious errors may result from doing so. This is clear from the test file I put below. However, I have found that this test file will work properly, with a tiny change to the split.screen

Hi all, As long as I've used R, add=TRUE hasn't worked in contexts like this: f <- function(x) x^2 X <- seq(0, 1, by=1/4) plot(f, col="blue") plot(X, f(X), col="red", type="l", add=TRUE) I attached a fix for version 2.6.2.

I use R on linux and I go through exceed from a windows machine. Depending on the amount of plots I do on a screen, sometimes the numbers on the vertical axis of the plots don't show up. I tried infinite of combinations of mar and cex but nothing helps. Yet, if instead of shooting the graphic upto the screen, I send it to a pdf file or a postscript file, the numbers on the vertical axis of

Hi, I make a graphic using xyplot, it is very good. xyplot((ocorrencia/isca)~frag|especie) But I need to plot a curve for each especie's plot. I try to use panel.abline and others panel., but I dont succeed. I need to plot the function exp(a+b*x+c*x^2)/1+exp(a+b*x+c*x^2), a b and c are different for each especie. Normally I use the curve function to add a curve in a points

If so, I apologize for not doing and would like to know where I should have filled it.
