Hi, I'am using the playwith library to write my own small GUI application.

Hi, I looking for a graphic device on Linux with more functionalities than the X11 (). I find the plotAndPlayGTK package and the playwith function. It is a good device. It is possible to make it default in my system. Now I need: > library(plotAndPlayGTK ) Loading required package: RGtk2 Loading required package: cairoDevice > > playwith(plot(1,1)) Error in plot.new() : figure margins

A new package, *latticist*, is available now from CRAN. Latticist is a graphical user interface for exploratory visualisation. It is primarily an interface to the Lattice graphics system, but also produces displays from the vcd package for categorical data. Given a multivariate dataset (either a data frame or a table), Latticist attempts to produce useful displays based on the properties of the

Hello, I am trying to execute an example provided in the help files for the playwith() function. I try to execute the first example: library(playwith) if (interactive()) { options(device.ask.default = FALSE) ## Scatterplot (Lattice graphics). ## Labels are taken from rownames of data. ## Just click on the plot to identify points. playwith(xyplot(Income ~ log(Population / Area), data =

Hi, I have the following problem: library(playwith) x<-ts(rnorm(100)) y<-ts(cumsum(x)) playwith({ par(mfrow=c(2,1)) plot(x) plot(y)}) I can't make playwith identify (using the button top left) datapoints on multiple graph plots (eg. par(mfrow=c(2,2) for a 2 x 2 frame of plots). Is it possible any other way? Many thanks in advance, Costas P Think

playwith package version 0.8-55 is now on CRAN. It provides a GTK+ interface for interacting with R plots.

Hi, I am having problems installing playwith on a Linux Mint ver. 8 (Helena) computer running R-2.10.1. <src/base/R-2/R-2.10.1.tar.gz> Anybody facing similar problems? Is it a GTK issue? I can not install the cairo related packages/libraries as well. Any pointers very welcome. Thanks + bestregards, Costas [[alternative HTML version deleted]]

Hello, I am having trouble installing the package playwith on the latest Mint "helena", running R version 2.10.1 (2009-12-14). I suspect it has to do with the GTK library but as far as I can tell there is nothing wrong with it. Any help extremely appreciated.

Helllo, I am having trouble with running the library Playwith in the R-2.12.0. running under 32bit Windows XP. After calling the library the error message "The procedure entry point gdk_cairo_reset_clip could not be located in the dynamic library libgdk-win32-2.0-0.dll." occurs and the R asks for instaling the GTK+ package. However the instalation of GTK+ thorugh the R fails. I have

Hi guys, I am new to R, so sorry if my problem seems trivial. Sometimes I encounter some lists, which I cannot index their components with [ . ] For instance the prcomp() function returns a 'prcomp' object whose components are some 'lists'. the second component is a list that comtains the following: > mylist <- churn[2] > class(mylist) [1] "list" >

Dear R users, When I tried to use princomp() from stats packages to do Principal Components Analysis, I am not very clear what is the "scale". And the scores are different from "PROC PRINCOMP" procedure from SAS. Using the example data from this package: restpc <- princomp(USArrests, cor = TRUE) > restpc$scale Murder Assault UrbanPop Rape 4.311735 82.500075

Hello, For basic linear regression lm() does the job well, for datasets that are larger than memory biglm() seems to work. I'm working on a parallel implementation of multiple linear regression for datasets that are too large for memory. Currently I am working over least squares: calculating: t(X) %*% X and t(X) %*% y separately in parallel on each node This generates a

Hello all, I'm currently using R to do PCA Analysis, and was wondering if anyone knew the specific R Code that could limit the output of the PCA Analysis so that you only get the Principal Component features as your output and none of the extraneous words or numbers that you don't want. If that was unclear, let me use linear regression as an example: "lm(y~x)" is the normal
