similar to: running multiple commands in one system() call

The latter is a better way to disable the qemu display output as we need to, without enabling extra devices (which are disabled already, anyway). Also, related to the change above, ban the -display parameter from the ones that can be supplied by the user. --- configure.ac | 8 ++++---- src/launch-direct.c | 12 ++++++++---- src/launch.c | 1 + 3 files changed, 13 insertions(+), 8

Hi all, Working at the R command line, how do I get strings to display e.g. tab or newline characters as they should be displayed, rather than as e.g. \n or \t? e.g.: > x="\t" > x="\t" > x [1] "\t" > print(x) [1] "\t" -- ==================================================== Nicholas J.

Hi, Let's say one has just run a command line command that took an hour and produced a huge matrix as an output. However, one forgot to store the output in a variable. Is there a hidden variable somewhere that stores the result, so that one doesn't have to re-run the analysis for an hour? E.g., x <- whatever_the_last_output_was Thanks! Nick --

Hi, Is there a way to parse a postscript (*.ps) file with R (or perhaps with some other command-line utility)? E.g., I have a map in postscript format with lots of features, but I just want to extract the coastline and it's coordinates. Any help very much appreciated! Cheers!

I am dealing with an object that sometimes has a certain attribute, sometimes doesn't. How do I check for this? "exists" doesn't work... ======================= > z=c() > z$a = c("c", "d", "f") > z $a [1] "c" "d" "f" > exists("z") [1] TRUE > exists("z$a") [1] FALSE

Hi all! I'm trying to build a simple class, but I'm getting a weird error. E.g. if I do: ========== gregion = setClass("gregion", contains = "data.frame", representation(name = "character", poly.x = "numeric", poly.y = "numeric" )) gregion$name = "North America" ========== Then I get this message: Warning message: In

Hi, This can't be hard, but I can't find the solution. I have a 380x380 data frame of numbers. I would like to turn it into a single column so I can do e.g. hist and mean on it without writing my own function. There must be a simple function for this, but I'm stumped -- reshape, dim, etc. don't seem to do it... Help appreciated! Thanks!! Nick --

Hi, I've written a function which I load with a source command. The function requires a certain library, phangorn, to work. I would like the function to check if phangorn is loaded as a library before running. For some reason, just putting require(phangorn) into the sourced function doesn't do anything. This must be simple, but I can't figure it out! Any help appreciated...

Hi all, a quick question I couldn't find the answer to in the usual places: Is there a way to turn off line-wrapping in the R console? Or set the line width-before-wrapping manually? Currently it looks like the console linewraps after about 70 characters, this occurs even if I increase the window size. (I want to output some simple tables to screen for students in a computer lab

Hi all, This can't be very hard, but it is sticking me because I am a beginner. Setup: x = rbind(c(0,1,1), c(2,3,1), c(4,5,1)) y = as.matrix(x) rownames(y) = c("a","b","c") colnames(y) = c("a","b","c") ordered_list = c("b", "c", "a") How do I produce a new matrix, z, with the rows and columns both

Hi, I have a script which I source, which evaluates a changing expression call hundreds of times. It works, but it prints to screen each time, which is annoying. There must be simple way to suppress this, or to use a slightly different set of commands, which will be obvious to those wiser than I... Here is a simpler mockup which shows the issue: x = data.frame(rbind(c(1,2,3),c(1,2,3)))

Hi, here's an obscure question someone can hopefully help with. I have some R code that uses stuff from parallel (now a part of the R core in 2.15 I believe), especially clusterApply. However, this seems to cause problems in R.app, and I've seen advice to not use these multicore functions, e.g. doMC, in R.app. So, I want to make this optional. How can have a program check whether

Hi, If I load 2 packages that have a function with the same name, how do I tell R to run one or the other? (Instead of having R automatically use the first- or last-loaded one, whichever it is.

Hi all, I googled this but no luck. I am using R.app 2.10.1 on Mac OSX 10.4. Here's the problem: When I type at the R.app command line and hit the carriage return "Enter" (right pinky, "Return" on some keyboards), it just adds a blank line. To actually get the command to execute, I have to go all the way over to the number-keypad and hit "Enter" there.

Hi all, I am running R.app on Mac OS X 10.4. I am trying to figure out if there is a .plist file of some sort, or a similar parameter file, that will let me turn on and off e.g. line-wrapping in the R.app GUI console. The only hint I could find online is this: https://stat.ethz.ch/pipermail/r-sig-mac/2010-April/007264.html ...but it doesn't seem to specify where to find the file in

Hi all, I'm using the R GUI on a Mac. It is easy to produce a number of plots and put them into a Quartz window, and then use Command-left or Command-right to flip between them. However, Quartz seems to hold a maximum of about 15 plots, and then discards anything plotted before that. This is pretty annoying, does anyone know of way to change this default setting? Cheers, Nick --

Hi, Is there an easy way to convert numbers into a form such that they all have the same number of digits? e.g.: "1", "10", and "100" ...become... "0001", "0010", "0100" etc. I ask because I am producing a large number of files that need to sort consistently by filename. Currently I get this kind of sorting: filename1 filename10

The previous code duplicated a lot of common code for reading and writing the cache file per data field. This change simply factors out that common code. This makes it simpler to add new tests in future. This is just refactoring, it should have no effect. --- lib/qemu.c | 375 +++++++++++++++++++++++++++++++++++++++---------------------- 1 file changed, 238 insertions(+), 137 deletions(-)

Hi, I have a simple task I can't figure out. I'd like to take some measurements I made, e.g.: year (y-axis) 1 2 3 4 5 6 counts (x-axis) 10 10 20 30 40 50 And then, make a barplot with the x-axis ticks (representing the borders between years) between the bars. However, barplot seems to force you to make the x-axis arbitrary categories. I want it to be continuous (as in a

I figured it out, at least enough to get rgeos's gSimplify function to work, which was my original goal; the stringr problem was with 0.2, however I got stringr 0.5 to install by changing the minimum version in DESCRIPTION from R2.11 to R 2.10. ...
