similar to: how to save a plot in a given size in inches or centimeters

Hi R users, I made a few research on how to convert inches into centimeters for graphics settings (especially width and height of the graphic device). Apart from the function layout() wich can be settled in centimeters using lcm(), I found that writing a function that convert centimeters into inches (i.e. x/2.54) was probably the best answer. Is there somewhere any parameter that could help

Hello, I'm trying to determine the width of a plotting point (in inches) in the grid package. I naively thought I could create a pointsGrob with only one point and get the width (as tried below), but this results in an object with a size of 0inches (changing cex has no effect). Does anyone have a better approach? Of course, it would be dependent upon the graphics parameters and viewport...

Hi, how can I convert the unit "lines" of par("mar") into inches? par("mai") could help, but does not (see code below). I want to plot a curve in a predefined size in pdf (I add some margin space to the plot width&height, everything is in cm): pdf("test.pdf",width=(20+2+4)/2.54,height=(10+3+1)/2.54) plot(10:30,

Dear R-list, Could anybody tell me where to find information about changing the measurement unit from inch to centimeters? I read the help from X11, I read R-intro and I did some searhing in the R archives, but I couldn't find the answer. For example, I would like to produce a plot of a certain width and height: X11(width=10, height=5) and I would like these to be centimeters, rather

Hi I want to draw sth in a pdf file with a predefined defined size. Say a 5cm x 3cm rectangle (a ruler): pdf("rect.pdf", paper="a4") plot(c(1,5,5,1,1),c(1,1,3,3,1),asp=1,axes="n") dev.off() but how do I fix that one unit is 1cm? Thanks thomas

Package grDevices has a function cm() to convert from inches to centimeters. Its definition is: cm <- function(x) 2.54*x As far as I can tell, the function is not used anywhere in the R sources (I grepped for "cm(", "cm)" and ", cm".) I did not check for all packages on CRAN, though. May I propose to remove this apparently useless function from the sources? [I

For those who don't follow Ubuntu development carefully, the first Beta for the next Ubuntu was recently released, so I took my home system and upgraded to help out with filing bugs, etc. Just to be clear, I am not looking for help with the upgrade process. I've had R, and a few miscellaneous CRAN packages installed on this computer for years. Today, when I loaded an R session I had

As an end-user, I wonder about Revolution R. Is the relationship between Revolution R and the R community at-large a positive one? Do the former contribute to the development efforts of the latter? Is there a competitive aspect? is their forum competitive with r-help? any other thoughts? (most of all, I simply hope that they help some of the many helpful experts on this forum, who have

Hi list, I was testing out the "doSMP" package from REvolutionR in my regular R2.11.0 installation and I got the following error message.? Well, one obvious thing is that R2.11.0 was built using "i386-pc-mingw32" which is different from what revoIPC used.? I could just use REvolutionR, but all my R peripherals were set up to work with the regular R2.11.0.? So, I really want

I know this is not a revolution support forum, but as anyone noticed the following? I have a foreach loop to generate random samples. If I run the exact code below in normal r (2.14.1) it works as expected, but if I run it from revolution 4.2.0 each loop returns the same numbers. The only way I can get revolution to give different numbers is using 1 instead of 8 in registerDoSNOW(makeCluster(8,

Hello How do you compare R to SAS in terms of speed and management of large datasets? What about Revolution R? I've seen on their site, they claim that Revolution R is much faster than R and it's multithread... Can you really notice the difference?. What dissadvantage does it have? I think it's based on R 2.10. but R already issued the version 2.12 Regards What alternative

Dear R-devel, REvolution appear to be offering ParallelR only when bundled with their R Enterprise edition. As such it appears to be non-free and closed source. http://www.revolution-computing.com/products/parallel-r.php Since R is GPL and not LGPL, is this a breach of the GPL ? Below is the "GPL and ParallelR" thread from their R forum. mdowle > It appears that ParallelR
