Dear Colleagues, When I try to install Rcmdr the following happens: ---------------------------------- > library(Rcmdr) Error in structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"), class = "tclObj") : [tcl] invalid command name "font". Error : .onAttach failed in 'attachNamespace' Error: package/namespace load failed for

Hi, I want to put text on a plot containing something like: a = b^2 = <squared numeric value of b> using bquote. Example: mu = 5 plot(1:10,1:10) text(2,8, bquote(delta == mu^2)) # This works text(2.5,8, bquote(phantom(0) == .(mu^2))) # but is unpredictable text(2,8, bquote(delta == mu^2 == .(mu^2))) # This doesn't work The last text function returns the error:

Hi, I repeatedly get an error when trying to read an SPSS v. 18 .sav file into R. > require(foreign) Loading required package: foreign > femaleSPSS.dat <- read.spss("female-04-02-2010.sav") Warning message: In read.spss("female-04-02-2010.sav") : female-04-02-2010.sav: Unrecognized record type 7, subtype 18 encountered in system file > However, read.spss works

There are a couple of points to keep in mind when doing a log-transform of an exponential model, such as -- y = a*exp(b*x) 1. The implicit statistical model is multiplicative in the error. The implied statistical model of the log transform is -- log(y) = log(a) + b*x + u which implies -- y = a*exp(b*x)*exp(u) A linear regression in the log

Hi, I'm responding to a post about finding roots of a cubic or quartic equation non-iteratively. One obviously could create functions using the explicit algebraic solutions. One post on the subject noted that the square-roots in those solutions also require iteration, and one post claimed iterative solutions are more accurate than the explicit solutions. This post, however, is about

Hi all, I am using * as a PBX for a Broadvoice VoIP account. It had been working well since about last November, although not perfectly (similar disconnection problems, although I am pretty sure it had to do with my PPPoE setup, but I think these issues were resolved). As of a few weeks ago, though, I started having serious problems. Basically, I can start up * and connect to Broadvoice and
