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 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

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, I posted in R-devel, thinking it might be a general R problem, but Uwe cannot reproduce it in his GNU/Linux distro, with the same R version. So I'm posting here to ask whether Debian R users are having this problem. I'm getting a segmentation fault as follows: ---<--------------------cut here---------------start------------------->--- R> begt <-

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 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

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 ==

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

Hi, How can we set the environment for the minuslog function in mle()? The call in this code fails because the "ll" function cannot find the object 'y'. Modifying from the example in ?mle: library(stats4) ll <- function(ymax=15, xhalf=6) { -sum(stats::dpois(y, lambda=ymax/(1+x/xhalf), log=TRUE)) } fit.mle <- function(FUN, x, y) { loglik.fun <- match.fun(FUN)

Hi, I'm trying to fit the following model to data using 'nls': y = alpha_1 * beta_1 * exp(-beta_1 * x) + alpha_2 * beta_2 * exp(-beta_2 * x) and the call I've been using is: nls(y ~ alpha_1 * beta_1 * exp(-beta_1 * x) + alpha_2 * beta_2 * exp(-beta_2 * x), start=list(alpha_1=4, alpha_2=2, beta_1=3.5, beta_2=2.5), trace=TRUE, control=nls.control(maxiter =

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'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, Suppose we need a function that takes a POSIXct object and need to calculate the time difference between it and GMT time: gmtDiff <- function(time) { time.gmt <- as.POSIXct(format(time, tz="GMT")) time.plt <- as.POSIXlt(time) dlstime <- ifelse(time.plt$isdst > 0, 1, 0) timezone <- as.numeric(difftime(time, time.gmt, units="hours"))

Dear Debian R users, This is more of an apt question rather than R. I have a testing Debian system, but would like to use the unstable packages for R, *without* using the -t flag in apt-get. I think this is done by using a 'pin' rule in /etc/apt/apt.conf, but don't understand how this should be done. Can somebody provide an example please? Cheers, -- Seb

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'm keeping a Debian unstable system, and recently found 2 problems: 1) building a package (R CMD build diveMove, available from CRAN) depending on KernSmooth fails with: ---<---------------cut here---------------start-------------->--- Loading required package: KernSmooth Error in dyn.load(file, ...) : unable to load shared library

Hi, Recently during an upgrade I was asked to use labels or UUID in /etc/fstab. I've done that and everything went fine, except for the only CD/DVD ROM device in my system. According to KInfoCenter (the KDE devide information application) the this device has the label: CD/DVD Drive. So I placed this line in /etc/fstab: LABEL="CD/DVD Drive" /media/cdrom0 udf,iso9660 user,noauto 0

Hi, Since upgrading to version 2.11.0~20100402-1, starting R fails with: /usr/lib64/R/bin/exec/R: error while loading shared libraries: libblas.so.3gf: cannot open shared object file: No such file or directory Is this occurring to others on sid? -- Seb

Hi, What is the best way to tell a locally-built R-devel (somewhere in the user home directory) to use the libraries from the Debian installation (i.e. /usr/local/lib/R/site-library and /usr/lib/R/site-library). I suppose this would take setting one or all of R_LIBS, R_LIBS_SITE, R_LIBS_USER in ~/.Renviron, but that would also affect the Debian R in the system so is not an option. How do R
