proposed change to 'sample'
There is a weakness in the 'sample' function that is highlighted in the help file. The 'x' argument can be either the vector from which to sample, or the maximum value of the sequence from which to sample. This can be ambiguous if the length of 'x' is one. I propose adding an argument that allows the user (programmer) to avoid that ambiguity: function (x, size, replace

plotting multilevel / lme lines
Dear expeRts, I am trying to plot a lme-object {package nlme) in such a way, that on a selected level the x-axis represents the value on a selected predictor and the y-axis represents the predicted-outcome variable. The graphs would than consist of several lines that each represent one group. I can't find such a plotting function. I could write such a function myself, based on

Is aggregate() what I need here?
I'm pretty new to R, and I've been given a script by a user who wants some help with it. I know enough about the way R works to know that this is a very inefficient way to do what the user wants (the LSB_JOBINDEX stuff is added by me so that this can work on many hundreds of input data files as LSF jobs - it's the nested loops I'm really interested in):

How to implement a schedule of recurring events?
Hello, I am fairly new to Ruby and Ruby on Rails. I am creating an application that "has many :groups", each with their own schedule of events. This is a little different than a calendar of events, since these events recur every week and do not have a specific date. So for example, I need to display a schedule for one group that looks like this: Group A''s Activities - Monday

lattice logaritmic scale (basis "e" ), rewriting labels using xscale.component
Hi there, sorry for troubling everybody once again, I've got a problem rewriting Sarkar's function for rewriting the tick locations in a logaritmic way (s. http://lmdvr.r-forge.r-project.org/code/Chapter08.R): His example works for log 2 but I need log e (natural logarithm). My problem is that if I replace 2 with "e" (using paste()), I get the error message that the location

Strange behavior with time-series x-axis
I recently called plot(x,y) where x was an array of POSIXct timestamps, and was pleasantly surprised that it produced a nice plot right out of the box: z <- as.POSIXct(c("2006-10-26 08:00:00 EDT","2007-10-25 12:00:00 EDT")) x <- seq(z[1],z[2],len=100) y <- 1:100 plot(x,y,type="l") The X axis had nice labels, one tick mark every other month.

Hola de nuevo. Leí mal. Si vas a eliminar esas filas, entonces usa: sqldf("select * from graph where sol!='lim' and dia!=2") En el correo anterior seleccioné precisamente a esas descartando a las demás.

How limits are set in a scales list
I have a lattice plot that has 4 pages with 4 columns and 8 rows per page. I wish to have the rows use a separate x-axis since their ranges are quite different, but I wish to have those same limits used on each page. By setting an element of the scales list to something like x = list(limits = lim.list$CFU, lim.list$CFU, lim.list$CFU, lim.list$CFU,

changes in src/unix/system.c break builds on FreeBSD
Dear R devs, For some days now (~ February, 4th), I am not able to build the recent tarballs of R-devel on a FreeBSD test box anymore.

trouble with plotrix package
Hello list, I wrote a simple program to plot data on polar axes, taking advantage of the plotrix package and its function radial.plot. The basic plot works fine, but I am having difficulties with the formatting. There are three problems, but I thought I would attack them one at a time. Here is the first: If my data set contains values with all vector lengths between 0 and 100 (and various

readline() to vector
Hi! I'm trying to use readline() to ask for xlim() and ylim() values for a subsequent plot. I'm doing: lim <- readline("Enter xlim and ylim values: ") then would like to use the values in lim for a plot: plot(etc, xlim=lim[1:2],ylim=lim[3:4]) The problem is that lim is a character,i.e., "10,20,-10,50" or "c(10,20,-10,50)" depending on the input to
