Dear R users, I am using R version 2.0.1 (2004/11/15) on an i386-pc-mingw32 platform. I encounter the following problem while using cumsum: > a <- rep(0.01, 100) > b <- cumsum(a) > sum(a) == 1 [1] TRUE > b[100] == 1 [1] FALSE Am I missing something? Should cumsum have such an outcome? Thanks in advance for any clarifications any of you can offer. Regards, Makram Talih --

Dear R-users, Is there a preferred method for testing whether a real symmetric matrix is positive definite? [modulo machine rounding errors.] The obvious way of computing eigenvalues via "E <- eigen(A, symmetric=T, only.values=T)$values" and returning the result of "!any(E <= 0)" seems less efficient than going through the LU decomposition invoked in

Would someone please tell me where I can find some good troubleshooting documents to resolve AD authentication issues when using Samba? Is this mailing list the best place? I was able to setup a working WINBIND-Samba setup on CentOS 7.6, but I am required to use SSSD on a different CentOS 7.6 server. Using a test VM, I can get services running, but I can't authenticate from a Mac or

Thank you for replying! I can login with my Active Directory credentials, but I can’t login using the local CentOS “svc_dictations” account. I created the local account usingusing “adduser”, “smbpasswd”, and then updating my smb.conf file (below).

Hi there, I have been using the example provided bellow for a while, and It was working without any problem. Nevertheless, just since 2-3 days is not working, probably because I did update.packages(). I have tried to re-install the older versions of the packages Hmisc() and xtable(), but still does not work. Can you run this example, and tell me if you got the same problems? I use

Hi Rowland, You are right. We are running some old software here, such as NIS. All these started in 20 years ago when I joined the group and we had about 20-30 workstations running Linux. NIS was chosen at that time to manage user accounts. Some users were not familiar with Linux, so we provided Samba to them so that they could map Linux file systems to their computers. I know NIS is old

Hi Rowland, Thanks for your quick response. Yes, it's Samba+sssd+krb5+AD. So many technologies wrapped together, and I don't know which part can go wrong. We managed to make them work together with the full domain name format such as yu.yale.edu\zs24. But it didn't work with short format as YALE\zs24. When I did this in a Windows computer, it reported "We can't sign you in

dear R wizards: an operation I execute often is the deletion of all observations (in a matrix or data set) that have at least one NA. (I now need this operation for kde2d, because its internal quantile call complains; could this be considered a buglet?) usually, my data sets are small enough for speed not to matter, and there I do not care whether my method is pretty inefficient (ok, I

I am having a problem with loading R on my 64 bit computer. It used to load perfectly until I upgraded to R 3.0.0 now it takes about 10 to even 20 minutes ? Does anyone know how to remedy this problem?

Hello everyone, We have a Samba server that experiences very strange problems. I wonder if anyone can provide some advice. This is a Redhat 8.4 machine with Samba 4.13.3. We setup Samba according to Redat document https://access.redhat.com/solutions/3802321 .It works well in most cases but has some issues. When user tries to mount a share from his/her PC, he/she must use the long format of

Hi Rowland, Thanks for your advice. I discussed this with my manager and we will plan to upgrade the old system. But this will not be finished with short time. After reading many old emails in this forum, I made some changes in our Samba settings. First, we turned on winbind and added all necessary packages and setup for winbind. Finally, we can login with the short format, such as YALE\zs24.

I am having trouble calling the lmer function in the {Matrix} package. I first installed and loaded {Matrix} as follows: > install.packages("Matrix") > library(Matrix) The package loaded successfully, however when I attempted to call lmer, I received the following message: Error: could not find function "lmer" I also tried: < ?lmer which produced no search

Dear R list, I've just installed R and then followed the instructions to install the package "geoR" from within R by using the following line of code: install.packages("geoR", contriburl = "http://www.est.ufpr.br/geoR/windows") This installed okay under the folder C:\documents and settings\ ... But when I follow the instructions in the illustrative session

Using Tinn-R (in windows) is possible to run latex and R from the same editor, which was great. Now, I am using Ubuntu-linux, which has been better than WinXP. Currently, I am using Emacs (and then install ESS) for running LaTeX and R from a same editor-program (like i was doing with Tinn-R in windows). Nevertheless, and even though i have been using Emacs for almost 2 years, it is not as
