Hi, When using method L-BFGS-B along with a parscale argument, should the lower and upper bounds provided be on the scaled or unscaled values? Thanks. Cheers, -- Seb

Hi, I've run into a ridiculous problem I can't find any solutions for in the archives or help pages: data(barley) cutYield <- with(barley, by(yield, variety, cut, breaks = c(0, 30, 60, 90))) As in this example, I'm using 'by' to return a factor for each level of another factor. The problem is that 'by' returns a list of the factors, and I need all these factors

Hello, I'm adding a private library tree in my home directory by adding this to my ~/.Renviron: R_LIBS="~/R/library:${R_LIBS}" so that once in R: R> cat(Sys.getenv("R_LIBS"), "\n") ~/R/library:/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library Is this the best way to proceed? Cheers, -- Sebastian P. Luque

Hi, I'd like to add, say, the sample size for every group in a bwplot as a parenthetical annotation to the axis. Here's a sketch: --8<---------------cut here---------------start------------->8--- require(Hmisc) age <- sample(1:100, 1000, replace = TRUE) sex <- gl(2, 8, 1000, c("Male", "Female")) grp <- gl(4, 6, 1000, letters[1:4]) bwplot(grp ~ age |

Hi, I admit that I rather carelessly built lots of large objects and therefore ran out of memory. Most objects, which I have at the moment are now unnecessary, but it would take a lot of time to recreate the last few ones from scratch. So I would like to erase (get rid of) selected objects in order to be able to continue. Does anyone know how I could do this? Machen Sie aus 14 Cent spielend bis

Hi, I came across a case where there's a discrepancy between minimum and maximum values reported by 'summary' and the 'min' and 'max' functions: ---<---------------cut here---------------start-------------->--- R> str(tt) num [1:1397] 1952 1970 1976 1967 1946 ... R> summary(tt) Min. 1st Qu. Median Mean 3rd Qu. Max. 1920 1960 1970

Hi All: This follows my earlier post on webized slides on lecture presentation on introducing R. I learned that in Mozilla (Firefox) browsers, the slides did not show up. Sorry for the no show. As a reluctant windows user, I kind of carelessly clicked through Powerpoint to convert the presentation file to its html form, unwittingly leading to the mess. See if it got corrected now (I do not have

Hi, The following code produces a plot on X11: splom(~iris[1:4], groups = Species, data = iris, panel = panel.superpose, key = list(title = "Three Varieties of Iris", columns = 3, points = list(pch = super.sym$pch[1:3], col = super.sym$col[1:3]), text = list(c("Setosa", "Versicolor", "Virginica")))) However,

Hi, I'm usually confused about when to use 'slot' or '@'. I've frequently read that it's always preferable to use accessor functions, so I would think the '@' operator should be avoided. However, ?slot contains the following advise: "Generally, the only reason to use the functional form rather than the simpler operator is _because_ the slot name has to

Hello, I've encountered the need to cut some chron objects of the form: R> mychron <- chron(sort(runif(10, 0, 10))) R> mychron [1] (01/01/70 16:36:20) (01/02/70 00:08:46) (01/03/70 16:54:49) [4] (01/04/70 06:45:00) (01/07/70 06:21:24) (01/07/70 18:28:44) [7] (01/08/70 00:47:05) (01/08/70 05:11:44) (01/10/70 01:07:53) [10] (01/10/70 17:46:53) into arbitrary (e.g. a given number

Hello, I'm trying to build a frequency table for a vector, broken down by the combination of factors. For further analyses, I need to have the result arranged in a new data frame, with the upper limit of the histogram's breaks, the per bin count, and the factors identifying each record. My problem is including the latter: ---<---------------cut

Fellow R-helpers, Suppose we create a histogram as follows (although it could be any vector with zeroes in it): R> lenh <- hist(iris$Sepal.Length, br=seq(4, 8, 0.05)) R> lenh$counts [1] 0 0 0 0 0 1 0 3 0 1 0 4 0 2 0 5 0 6 0 10 0 9 0 4 0 [26] 1 0 6 0 7 0 6 0 8 0 7 0 3 0 6 0 6 0 4 0 9 0 7 0 5 [51] 0 2 0 8 0 3 0 4 0 1 0 1 0 3

Hi, The following produces almost exactly what I needed. The problems are that the 'panel.dotplot' call (commented) generates the error 'Error in NextMethod("[") : argument "subscripts" is missing, with no default'. The other problem is that the colors alternate between the levels of the 'site' variable, rather than 'year'. barley$yield2

Hi, I'm having a bit of trouble with 'scales="free"' in the segplot() function of latticeExtra. Say we need panels for each year, showing only those counties that are represented in each one: ---<--------------------cut here---------------start------------------->--- library(latticeExtra) data(USCancerRates) uscr.w <- subset(USCancerRates, state ==

Dear R-helpers, I need to show a linear fit through a subset of the data within each combination of levels of two factors. So I prepared an xyplot with different panels for each level of one of the factors, and different symbols within each panel for the levels of the second factor. My problem is selecting the subset of each combination through which the line should be fit for subsequent

Hi, The following call: xyplot(incidence ~ year, melanoma, panel=panel.smooth) produces a blank plot region with an error message: Error using packet 1 plot.new has not been called yet > sessionInfo() R version 2.11.1 (2010-05-31) x86_64-pc-linux-gnu locale: [1] LC_CTYPE=en_CA.UTF-8 LC_NUMERIC=C LC_TIME=en_CA.UTF-8 LC_COLLATE=en_CA.UTF-8 LC_MONETARY=C

I am using R 2.0.1 Patched on Windows 2000. I have created a binary package for Windows that builds, checks, installs and works without errors. In some of my .Rd files, I have links to functions in the standard packages supplied with R as well as links to others in add-on packages that I have installed. For instance, one .Rd file has the following snippet: \seealso{

Hi everyone, Thank you for all your input; may I pose you one last question? If I wish to _ensure_ that I can _always_ do real-time encoding, what is the cheapest AMD chip I should buy? I really don't need "better than real-time" encoding, but I do wish to be sure that the CD is ripped when I am finished listening to it, so that I can carelessly eject it without checking if the
