Hello R users I am looking for a package to visualize "relatively planar" directed graphs, with say 100 nodes and specified using an adjacency list. 'Rgraphviz', currently listed on the R-FAQ, seemed suitable (FAQ version 2.9.2009-06-05) But when I looked for the package, I found it had been recently "removed" and was instead directed to archive copies

Hello all This is my first posting for some years. I am back using R again and must say I do like the language (regarding scripting, I also use matlab, perl, and bash). My question involves plotting a Pareto frontier in three dimensions. This is strictly a exercise in visualization, I make no attempt to extract the Pareto set (aka dominating subset) first. EXAMPLE PLOTS For some example

Hello R-help My recent post on this topic has now been reworked and added to the R-wiki. http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:display-images I am more than happy to take comments (on or off-line) and enter any relevant changes. Regarding the proposed R documentation list, I think this could be a good idea and probably a better place for this kind of traffic.

Dear R-help I want to display an image file in a new plot frame. SVG is my preferred format, but I can also consider PNG, GIF, JPEG, TIFF, and PPM (from ImageMagick). By way of background (although not material to this posting), the image file is generated by a call to 'dot' (part of the 'Graphviz' suite) after the required .dot file has been produced using hand-crafted R code.

It is most likely that your grub.conf file is _different_ than menu.lst. grub.conf is just a dummy symlink made by RH under /boot/grub as well as under /etc to make peoples lives easier. (Or harder as the case maybe) If the contents of grub.conf is what you want to use for your bootup listing.. cd /boot/grub mv menu.lst menu.lst.bak cp grub.conf menu.lst rm grub.conf #optional step ln -sf

Hi, I'm trying to read a .mat file into R (2.11.1) with medium success so far. The file I have is a MATLAB 5.0 MAT-file exported from RiverSurveyor LIVE software (http://www.sontek.com/software.php). I have R.matlab and Rcompression installed and readMat() starts reading the file, as can be seen in verbose mode (hence medium success), but then gives the following error: Error in dim(matrix)

Hi again, One important correction of my first message: I misinterpreted the output. Actually in that R session 2 input files were processed one after the other in a loop. The first (with 88 parts went fine). The second (with 85 parts) produced the sendMaster errors and failed. If (in a new session via Rscript) I only process the second input file it will work. The other observations on R vs

At first our datacentre techies thought that lilo was forcing the old kernel. They altered lilo.conf & rebooted. It now seems that although the grub config file shows all 3 kernels & the newest is the default - when the system reboots - only the oldest kernel shows on the GRUB screen & only the oldest kernel boots! What can we do to get the newest kernel to boot instead? Regards,

Hi Tomas, Thanks for your prompt reply and your offer to help. I might need to get back to this since I am not too experienced in debugging these kinds of issues. Anyway, I gave it a try and I think I have found the immediate cause: I installed the debug symbols (r-base-core-dbg), placed https://github.com/wch/r-source/blob/tags/R-3-5-2/src/library/parallel/src/fork.c in cwd and changed the

Hello R experts, I have go this data frame: 'data.frame': 1 obs. of 20 variables: $ Anno : chr "PREVISIONI VS TARGET" $ OreTot: num 41 $ GioTot: logi NA $ OrGTot: logi NA $ OreCli: num 99 $ GioCli: logi NA $ OrGCli: logi NA $ OreFor: num -27 $ GioFor: logi NA $ OrGFor: logi NA $ OreOrt: num -18 $ GioOrt: logi NA $ OrGOrt: logi NA $ OreSpo: num -6 $ GioSpo: logi

Hi all, With the help of Tomas, I was able to track the issue down: Prior to R v3.6.0 the parallel package passes an uninitialized variable as the file descriptor argument to the close system call. In my particular R session this uninitialized variable (reproducibly) was holding the value 7, which corresponded to the file descriptor of the write end of the pipe the second child would use to

Hi, I am facing a very weird problem with parallel::mclapply. I have a script which does some data wrangling on an input dataset in parallel and then writes the results to disk. I have been using this script daily for more than one year always on an EC2 instance launched from the same AMI (no updates installed after launch) and processed thousands of different input data sets successfully. I now

Dear R friends. After having some troubles learning how to create a ffdf object, now I find myself having problems saving it. this is the data i´d like to save: str(DATA) List of 3 $ virtual: 'data.frame': 6 obs. of 7 variables: .. $ VirtualVmode : chr "double" "short" "integer" "integer" ... .. $ AsIs : logi FALSE FALSE FALSE

Hi Adam, I hope this is what you wanted: dat1<- read.csv("example.csv",sep="\t",stringsAsFactors=FALSE) ?str(dat1) #'data.frame':??? 102 obs. of? 5 variables: # $ species? : chr? "B. barbastrellus" "E. nilssonii" "H. savii" "M. alcathoe" ... # $ period?? : chr? "dusk" "dusk" "dusk"

Hi Andreas, thank you very much, good job finding it was EBADF. Now the question is why the pipe has been closed prematurely; it could be accidentally by R (a race condition in the cleanup code in fork.c) or possibly by some other code running in the same process (maybe the R program itself or some other code it runs). Maybe we can take this off the list and come back when we know the cause

mdbox format is a cross between mbox and sdbox. The idea is that it keeps up to mdbox_rotate_size sized mbox files which contain mails. Using zlib here will not help, because zlib is not applied to the full mdbox file, but individual mails within. Also not sure why you think that adding compression would make things faster? =) I am not fully sure how cephfs works but you might get better

Hi all, Im currently having an issue with Samba (at least thats where I believe the problem lies) and Windows 2000 and Windows XP clients. The problem occurs when some of the clients will go to load a document with Word or Excel, and lo, the client machine crashes, or the program opening the document freezes. This is usually worked-around as the offending program will generally work OK if the

Hi Andreas, the error is reported when some child process cannot send results to the master process, which originates from an error returned by write() - when write() returns -1 or 0. The logic around the writing has not changed since R 3.5.2. It should not be related to the printing in the child, only to returning the value. The problem may be originating from the execution environment,
