I have data on number of vines per tree for ~550 trees. Over half of the trees did not have any vines and the data is fairly skewed (median = 0, mean = 1.158, 3rd qu. = 1.000). I am attempting to investigate whether plot location (four sites), species (I'm using only the four most common species), or tree dbh has a significant influence on the number of vines per tree. When I

Dear, I'm a master student mathematics at university Gent, who's writing a thesis about vines and copula's. I'm in trouble with the package 'fCalendar' which I need for running 'QRMlib'. The problem is that 'fCalendar' doesn't have a namespace. I need to use R.2.14.1 because I also need the package 'vines' which only works for R.2.14.1. I'm

R gurus, I have a data set that looks something like this: Site Species DBH #Vines G PLOC 45.9 4 G ACNE 23.3 1 G ACNE 12.0 0 G FRAM 35.9 5 G AEGL 11.2 2 N PLOC 77.3 12 N JUNI 78.6 7 N ACNE 18.9 1 N ACNE 15.7 3 N ACRU 35.5 4 H ACSA2 24.1 6 H ULAM 35.2 7 There are 730 individual trees (22 species) from four sites in the actual data set. I would like to create a second data frame that

Hi, I've been toying with the idea of using the Linux machine as a print server. I'm using RedHat 5.2 and Samba 2.0.3. I already have one remote printer share working... but I can't figure out where the PrintTool in RedHat is storing the remote printers IP address. Anyone know where? :) (not important just bugging me - I hate when OS's hide stuff) I have the Samba book

Guys, I''m frankly overwhelmed by the number of Rails authentication options(?) out there...from ActiveRBAC to acts_as_authenticated to LoginEngine and so on...so many options, yet on resource I''ve found really distinguishes between each. This is sad, as authentication and user management is really an area where some Rails simplicity pixie dust could be a real boon to

Hi, I'm in the process of trying to convince my organization to move from an exchange server, to a samba solution, while retaining their original windows environments, including Outlook clients. I thought I had all my issues covered, and suddenly I'm facing a show stopper. it turns out that a lot of my users "documentation" has been stored on "public folders" on the

Need some pointers here. I've got CentOS 4.4, and I want to control my OSX 10.4.9 box via VNC. It connects, and I get a little dot for the mouse cursor, but just a black screen. I can see the mouse controlling the OSX desktop... Here's the output when I start in a terminal: [d at f ~]$ vncviewer VNC server supports protocol version 3.889 (viewer 3.3) VNC authentication succeeded

Thanks to David and Jorge - both of your helpful suggestions got me to the desired endpoint. In case anyone else has this question: I boxplotted my y variable data, but did the "cut" operation on the x variable in order to conserve the order of the y data. I see another suggestion coming in from another user that basically says this. So, my working line of code was: boxplot(count$RPKM

Hello R users, I have a set of data frames for which I am tallying row numbers, as shown below. > nrow(mC_Explant) [1] 14480 > nrow(mC_Callus) [1] 23320 > nrow(mC_RegenPlant) [1] 8108 etc. I want to create a new data frame which has the variable names as column headings, and then a single row with the nrow tallies. My first step was this: dfIntron <- c(nrow(mC_Explant),

Sers! I recently strumbled across llvm-qemu (http://code.google.com/p/llvm-qemu/) which apparantly should be able to translate qemu supported architectures to LLVM IR (http://markmail.org/message/iyqzgtcux62wdhkb) to ease analysing binaries. Using LLVM for (dynamic binary) translations seems to be a great idea. However I haven't seen many approaches being made in that direction.

Dear useRs, I have a slightly complicated data structure and am stuck trying to extract what I need. I'm pasting an example of this data below. In some cases, there are duplicates in the "gene_id" column because there are two different "sample 1" values for a given "sample 2" value. Where these duplicates exist, I need to average the corresponding

My games Heroes might and magic 5 tribes of the east and Civilization 4 are crashing on load in wine. They loaded before when I was using the Ubuntu drivers. Ever since I have changed to The ATI drivers have my Games stopped running. I have added the following to /etc/X11/xorg.conf Code: ection "Device" Identifier "aticonfig-Device[0]" Driver "fglrx" Option

Hello R users. This is a fairly basic question: I am concatenating data from sets of files in a directory using a loop. The column names in all files are exactly the same. My understanding is that rbind takes column names from the first file it reads. However, my output is showing that the column names are treated as a first data row, not treated as headers. I compile my file names like this:

Dear useRs, A colleague has sent me several batches of output I need to process, and I'm struggling with the format to the point that I don't even know how to extract a test set to upload here. My apologies, but I think that my issue is straightforward enough (for some of you, not for me!) that you can help in the absence of a test set. Here is the scenario: # Data sets are lists: >

Dear R Gurus, Let's get the technical details out of the way first: Computer: 1.83 GHz MacBook R version 2.5.1 I have a data set that contains the following variables: site, species, total.vines. I need to partition the main data set by site, the further select only those species that occurred at each site. When I select by site (site.name<-subset(data frame,Site=="Site

Hi, I've been using Samba for a while in lots of places and this is the first time I've encountered this problem: I'm using 1.9.18p7 on solaris-2.6, there's a large PC network here with win95 and winNT machines all belonging to a different workgroup then the samba machine. There are no problems with the winNT clients. However, the win95 machines sometimes give the following
