Runs up and runs down test
...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 the "runs.test()" in the
tseries package.

Problem compiling R 2.1.* on SUSE 9.2
...any error codes. Perusing /var/log/messages doesn't seem to
yield any clues. The system is a KDE AMD XP 2100, there is 1 GB of system
ram, less than 10% of the harddisk space is in use, videocard is an nVidia
GeForce4 Ti 4400. The OS is SUSE 9.2 and it has current updates for
security.

R project web site
...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.

Connect to postgreSQL
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

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

Compiling R
...be back-spaced over a
recalled command to edit it. I expect that I am missing a "--with-" statment
but I am not certain what it should be. Is there any help file that details
the fine points for compiling R? INSTALL does not contain the information I
am interested in.
Thank you,

Mann-Whitney U
Hi,
Could someone please tell me how to perform a Mann-Whitney U test on a

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

Font problem
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

pair() and X11 fonts error

"Error in text.default(x, y, txt, cex = cex, font = font) :

However pairs(iris) works fine. Since the iris data set contains considerably
more variables than hills, I am at sea regarding the correction.

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

about multi-optimal points
Hi Ulrik,
Thanks for your suggestion, but it was not what I meant. I tried to use the
rPref package but just got a very small sample and felt clueless.
