Can someone point me to an implementation of the "runs up and runs down" test, or does such beast exist in R? From web searches the "runs up and runs down" test is commonly used for testing pseudo-random number generators and in simulations. John C. Davis describes its use in geology in his book on geological statistics (2002). Having searched the full site, I can locate only

I have been unable to compile either R 2.1.0 or 2.1.1 under SUSE 9.2. The system simply hangs as far as I can tell. All key board and mouse service dies. I have had no problem compiling earlier versions of R through 2.0.1, aside from remembering to include readline in the configuration. Configure runs without any warnings except that Info or html versions of the R Manuals. The SUSE 9.2

Is anyone else encountering trouble viewing the basic www.r-project.org page? Or has it been changed recently so that google hasn't kept up? I find I can access the mirror of the CRAN page at http://www.maths.bris.ac.uk/R/, none of the *.org pages. Nor can I jump to the R homepage from the CRAN mirror. JWDougherty

I am using RStudio Version1.0.143 on a Windows 7 machine. R version 3.4.0 I am trying to connect to a postgreSQL database with the following command, but I receive an error message that says my password is incorrect. Since I saved my password in a file, I think I remember it. I searched for a solution online, but cannot figure out what to do. If I have to change my password, please provide

I have a generally successful compiled R 1.8.0 version installed on a SuSE 9.0 system. One frustration however is that the basic keyboard functions of BASH have not completely carried through and the up, down, left and right arrow keys don't behave as they do on the regular shell command line. That is no command history can be accessed and the cursor cannot be back-spaced over a

Don't waste too much time on this. It is due to a change introduced in Java 10 at short notice. I believe the rJava maintainers are working on a fix/workaround. -pd > On 31 Mar 2018, at 10:22 , John <jwd at surewest.net> wrote: > > On Tue, 27 Mar 2018 22:25:33 +0300 > Luis Puerto <luiss.puerto at gmail.com> wrote: > > I don't run a Mac so this may not

Hi, Could someone please tell me how to perform a Mann-Whitney U test on a dataset with 2 groups where one group has more data values than another? I have split up my 2 groups into 2 columns in my .txt file i'm using with R. Here is the code i have so far... group1 <- c(LeafArea2) group2 <- c(LeafArea1) wilcox.test(group1, group2) This code works for datasets with the same number

Some plots fail due to a problem with the X11 fonts. I get a message that "X11 font at size 22 could not be loaded." The demo() graphics routine for instance dies during the third chart. The graphics demo calls "font.main=1" and that seems to be where the error is. I believe this is due to a configuration problem on my system, however I can't find where in the

I am encountering an font error when using either plot() or pairs() for a scatter plot matrice under some circumstances. For instances pairs(hills) using the "hills" data set in MASS results in the following error: "Error in text.default(x, y, txt, cex = cex, font = font) : X11 font at size 16 could not be loaded" However pairs(iris) works fine. Since the iris

I'm running R 2.4.1 on SuSE Linux 10.2. My system is an AMD based PC with 2 Gigs of ram and abundant HD space. I have always run R from the console without problems, but in the interests of broadening R's user-base, and reducing the complexity of my computing environment, I am hoping to convince my PTB that R is a viable alternative to Excel under Windows - heh. Since they like

Dear all I prepared some image processing routine which depended on package ReadImages. Basically I imported image to R, changed rgb to grayscale, normalised an image made some selections and changed to image by imagematrix. Recently I learned that this package was removed from CRAN and can not be used in R 3.0.0. What options I have now to import image to R, change it to grayscale, make some
