Gurus: I keep seeing other people?s code that contain ideas like If (x == 2L) X[-1L] X - 1L I have some idea of what?s going on, but where is the use of concepts like ?2L? documented?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This is for the same file server I wrote about earlier. I would like to restrict access by group, as defined in LDAP. The obvious solution is to add a filter to the login LDAP search that restricts to gidNumber=10038 or 10001, since those are the groups I need. From what I'm seeing, I need to add that to /etc/ldap.conf in the nss_base_

I am really new with R Graphical user interfacefunctions. I am developing a software package to calculate pKa (biochemistry) but I want to make it look aesthetically pleasing and make it user friendly. I have heard that R has some GUI (Graphical user interface) and you can do some really cool stuff out there. What are the limitations and what are some resources for help. I have found a couple of

Hello, Is there any way I can use the gregexpr functions (or a different function) in a manner that will also return overlapping (i.e. non disjoint) regular expressions? For instance, when running gregexpr("AAA","AAAAAA"), I get two matches, one at position 1 and one at position 4. I'd like to receive 4 matches at positions 1, 2, 3 and 4. Thanks, Schraga

I think I more or less understand what a ?wrapper? is, but I?d like to hear how more experienced R users define it, and especially I'd like to know if there is a formal definition. In my reading, it seems like there are a fairly wide range of meanings, but they are all conceptually similar. I've looked in a couple of the classic R texts, the extensions and developers' manuals, and R

Hello Folks. This must be a silly question with a (not) obvious (to me) answer. Consider this: tmp <- matrix(1:200, nrow = 20) vec <- 300:309 tmp[9,] <- vec # replacing one row works fine p <- c(3, 11, 17) tmp[p,] <- vec # replacing multple rows pastes the values down a column and recycles vec. What I want to do is replace multiple rows simultaneously at once. I suppose I can

Our fileserver (running RHEL 7.4) has suddenly stopped allowing access to network shares through Samba. It is running Samba 4.6.2. When someone tries to mount a shared folder it prompts them for a username and password which fails even when the password is correct, rather than using their valid Kerberos ticket as it has in the past. Anyone here has a similar experience or suggestions as to

Just a note to people if you're wondering why I'm not replying to most of my mails: I'm trying to get into university to start stydying cellular biology (so I'm applying to biochemistry and biotechnology). Their entrance exams are next wednesday, so I'm trying to use most of my time left to study for them (and also do some work..). I don't know much about the subject, so I

Hello all, since we're on the topic of R-editors. I am using emacs/ess on a unix workstation (to interact with R and have been having a little problem. I usually write the R commands I need to run in a separate buffer then copy and paste them into the *R* buffer for evaluation. The problem is, if any command is spread over multiple lines emacs/R hangs when I paste it in the R buffer for

Hi Folks... No code to troubleshoot here. I need some suggestions about the right terminology to use in further searching, and any suggestions about R pkgs that might be appropriate. I am in the planning stages of a project in which IR, NMR and other spectra (I'm a chemist) would be collected on various samples, and individual samples would be followed over time. The spectra will be feature

Dear All, I just apt-get source r-base-core and noticed that file "rules" under ./r-base-3.2.4-revised/debian contains (lines 277 to 279) --with-system-bzlib \ --with-system-pcre \ --with-system-zlib \ I wonder if these are still necessary and, in fact, when building R alpha (specifically, R-alpha_2016-03-21_r70361.tar.gz) I get a warning saying that those options are not

Hello, I was wondering whether a Poisson mixture modeler/cluster analysis package is available for R. I scanned CRAN packages and couldn't find anything but I thought I'd ask. If not could anyone recommend a non-R open source package. I have found 'snob' but this program seems a bit hard to use in an automated, non interactive fashion. regards, Murad -- Murad Nayal M.D. Ph.D.

Hi all, I have loaded a table called 'data' and used the split command to create a new table called 'datasplit' based on the variable 'a.ImageNumber' in 'data'. a.ImageNumber just specifies the image number that certain measurements are associated with (so there could be 330 measurements from image 1 and 297 measurements from image 2 etc). I would now like to

Dear R users I have a list, as follows: > intvl.period.myrs $Devonian [1] 4.8 4.2 9.5 5.7 $Ordovician [1] 7.2 5.1 10.2 1.9 $Silurian [1] 4.7 3.0 7.8 2.0 3.3 1.6 2.6 2.7 I want to write a loop that will sum up the values in each part, and give me a vector containing the (in this case 3) summed values this is what I have so far: for (i in 1:length(names(intvl.periods.myrs)) {

Hello Core Folk. Quite by accident I discovered today that col2rgb, when fed factors, acts on the integer representation of those factors: td <- as.factor(rainbow(5)) # not how I discovered the issue! td res <- col2rgb(td) res # but col2rgb("#FF0000FF") # this is td[1] but does not produce the same answer res[,1] # moreover as.integer(td) col2rgb(5) # the integer value of the

I have just used the RAqua.pkg to install R, and it doesn't work! I have Mac OS X 10.3, and the old version of R works OK, but the .pkg thing installed, and then when I double-click on the "StartR" application nothing happens. Nothing at all, no little icon bobbing up and down in the dock, just nothing. What have I done wrong? I didn't have to install the other packages

Dear whom this may concern, I am having problems running R under windows XP. I can source files and get all the functions loaded, but when directing it to a file to carry out analyses it comes up with an error message. I am using R for analyses of gpr files generated from microarray slides using Axon genepix 2000. I hope you have a solution to my problems. Kind regards, Jan Bart Rossel (PhD

Hello R Folks... Using the example below, I¹d like two of the panels to be plotted with type = ³p² but the third to be done with type = ³h². I can¹t use type = c(³p², ³p², ³h²) because this syntax applies all given types to every panel. I don¹t think I can use groups and distribute.type because these are intended for different styles of plotting within a single panel. As you can see, I tried
