The cubic regression of my model is significant and I want to plot a line that best fits. It's not abline() function, because it has a curve. Please, how can I plot it? --- Fernando Andreacci Biólogo Fone +55 47 9921 4015 fandreacci@gmail.com [[alternative HTML version deleted]]

I'm trying to make a monthly boxplot using this: boxplot(varmeasure ~ vardates) vardates = [1] 10/1/2010 10/1/2010 10/1/2010 10/1/2010 10/1/2010 10/1/2010 10/1/2010 [8] 10/1/2010 10/1/2010 11/1/2010 11/1/2010 11/1/2010 11/1/2010 11/1/2010 .... varmeasure = [1] 0.0 26.0 0.2 -0.2 -1.2 -0.8 0.0 4.4 -0.6 -0.2 14.4 -0.2 [13] 4.8 4.0 2.8 3.2 3.8 3.2 -11.4 0.2 0.4

Dear Friends, Yesterday I posed a question to the list concerning the possibility of doing animation examples in R. Here is an example S-Plus (4.5 for Windows ) that I wrote to illustrate my problem. If I try this in R (comment out the graphsheet and guilocator calls) I don't see my results until after the function has iterated through the 100 trials. I would like to plot each iteration.

Hi everyone, I am desperately looking for a method to interpolate strings within an SQL statement as follows: I get a lot of rows out of a database (in my example POSITION_to_ZIPCODE Database with holds records for German ZIP Code <--> Gauss-Krueger Coordinate System ) and want this to be selected and computed individually row by row as follows: library(RODBC) channel <-

Dear All, I am not very into object-oriented programming, but I would like to learn the ropes for some R applications. Quoting from the online R language definition (paragraph 5.1) > Consider the following simple example. A point in two-dimensional > Euclidean space can be specified by its Cartesian (x-y) or polar > (r-theta) coordinates. Hence, to store information about the location

Hi, I'm looking for the way to make vector plot over a time line. This plot, similar to the "feather plot" in Matlab, is a line in which every thick (a time value) one vector is drawn with its length proportional to one variable (wind speed, for example) and its direction to another (wind direction, for example). Any ideas? Thanks, EKS -- ---------------------------- Eduardo

Hello. Is it possible to set specify the font used by legend()? I would like to specify a fixed-width font so that I can line up parts of vertically stacked curve labels. For example, it would be nice if I could align the names, ages, and weights in the following three curve labels: Bob age=7 weight=100 Alexander age=13 weight=150 Susan age=20 weight=130 Is there perhaps a clever

Hello all, Is it possible to change the radii line type in radial plots? I wasn't able to find anything online.

I've wrote some code to simulate a random walk in 2 dimensions on a lattice. Basically I want to add something in to make it plot it point by point so you can see what is going on. Heres my code for the random walk in 2d RW2D<-function(N) { i<-0 xdir<-0 ydir<-0 xpos<-vector() xpos[1]<-xdir ypos<-vector() ypos[1]<-ydir for (i in 1:N-1)

Hi all, these are the remaining unapplied patches of the ARM HDLCD patch series. Changes in v7: - rebased on b61ed421d2c85b5b106c63f2c14f8aa162b282f0; - turn more printk and panic into early_printk and early_panic. Changes in v6: - rebased on 77d3a1db3196b1b5864469f8d3f41d496800c795; - remove useless initializations to NULL in lfb_init; - more compact checks in lfb_init. Changes in v5: - move

Hi all, Roger Peng and Jason Turner's suggestion with ImageMagick seem to be the simplest "dirty" way to get the problem solved. But I ran into yet another interesting but quite round-about way to solve the problem (partially). Through tcltk package, one can read in the gif image with > x <- tkcmd("image", "create", "photo", file=mypic.gif)

I am very confused about this. I want to convert a string to a name so I can use it to extract an element of a data frame using `$'. Here is my (non-working) code: do.graph <- function (meas) { fn <- paste("a", meas, ".dat", sep='') themeas <- read.table(fn, header=F) ameas <- as.name(paste("a", meas, sep=''))

How can I look up the aspect ratio of a plot, so I can use that to correctly adjust the angle of text which is supposed to be parallel to a line in the plot? The following example code works for a 1:1 aspect ratio, but puts the text at the wrong angle if the plot region is short and wide or tall and narrow. I can't find a par() component containing the plot aspect ratio. It will be for

Hello, I would like to know more about how to use the "apply" family and have attempted to convert nested "for" loops in example code from Contributed Documentation ("The Friendly Beginners' R Course? by Toby Marthews (ZIP, 2007-03-01)") to an "apply" function(s). The relevant code is: distances=c(51,65,175,196,197,125,10,56) #distances of 8 houses

Hi listers, A few days ago I posted a question about the use of the stars function on selected lines of a frame. Thanks to two helpers, a closer look at the scale argument allowed to partially solve the problem. Yet I still have a problem with stars. Allow me to explain what I intend to do (sorry for my poor English and the long post): I want to graph an activity index of a fish during the day

Hi, I was wondering if someone in the mailing list has any insight into this segfault error that I consistently find when running a script containing heatmap() in R 2.8.1 and 2.8.0 on a Linux 64-bit machine. Some points: 1. This occurs when running heatmap(). 2. Interestingly, if I source() the script or copy and paste the script in its entirety, this error occurs. However, if I run the

Hi everyone, I want you all help me to give an idea, how to draw pentagon with points? Maybe can use function, but I'm stuck. Yhank you. -- Hemavathi Ramulu [[alternative HTML version deleted]]

Hi, is there a way to place text at the upper left corner (or another corner) of the plot? I want to place it really at the upper left corner of the whole plot (the file I get), not at the upper left corner of the plot-region. I tried text() and mtext(), and corner.label() of the plotrix package but it didn't work out. thanks!
