[R] figure margins too large in RGtk2 drawing area as cairo device - why?

When using a gtkDrawingArea as a Cairo device I very often encounter the error: figure margins too large Even for the below getting started example from http://www.ggobi.org/rgtk2/ this is the case. win = gtkWindow() da = gtkDrawingArea() win$add(da) asCairoDevice(da) [1] TRUE plot(1:10)

[R] Warnings when plotting after x11() in R 2.14.2

Dear R-help, I recently upgraded from R 2.13.1 to R 2.14.2 and now get warning messages when plotting after using x11(). Example: plot(rnorm(10))### no warnings x11(); plot(rnorm(10)) Warning messages: 1: In axis(side = side, at = at, labels = labels, ...) : Font family not found in

[R] read.xls - ampersand different in XLS and XLSX

Hi All, I'm using read.xls from GDATA and it seems to be treating ampersands differently depending on whether the source file is an XLS or the more current XLSX. Ampersands from an XLSX become amp;. As a test I have a csv: write.csv(data.frame(a=c(JERRY, DICK LINDA)), ampersand.csv,

Re: [R] figure margins too large in RGtk2 drawing area as cairo device - why?

Peter, thanks for the answer! Indeed, it does work if I set par(mar=c(0,0,0,0)) but not when it is set to the default values mar=c(5.1, 4.1, 4.1, 2.1). The par settings returned in the example are the defaults, so no extraordinary big mar settings or char size (see below). Also, it does not

Re: [R] Reading in 9.6GB .DAT File - OK with 64-bit R?

My opinion is that you should be spending your effort on setting up a SQL engine and importing it there. If you have 32GB of RAM your current direction might work, but working with sampled data rather than population data seems pretty typical for statistical analysis.

Hi Jeff Steve, Thanks for your responses. After seven hours R/machine ran out of memory (and thus ended). Currently the machine has 4GB RAM. I'm looking to install more RAM tomorrow. I will look into SQLLite3; thanks! I've read that SQL would be a great program for data of this size

Hi Barry, You could do a similar thing in R by opening a text connection to your file and reading one line at a time, writing the modified or selected lines to a new file. Great! I'm aware of this existing, but don't know the commands for R. I have a variable [560,1] to use to pare down the
