Hi all, Is there a way to get cran R to set the working directory to be wherever the source file is? Each time I work on a project on different computers I keep having to set the working directory which is getting quite annoying. Thanks, Sachin [[alternative HTML version deleted]]

Hi all, I am looking for recommendations/pointers about best report generator you think that are currently available? i.e. the package that can help turn console output into nice-looking neat report to send to bosses? thanks a lot! [[alternative HTML version deleted]]

Hi All, I have a very (very) large tab-delimited text file without headers. There are only 8 columns and millions of rows. I want to make numerous pieces of this file by sub-setting it for individual stations. Station is given as in the first column. I am trying to learn and use sqldf package for this but am stuck in a couple of places. To simulate my requirement, I have taken iris dataset as an

AFAIK a script run through source() does not have any legit way to learn about it's own location. I need this to make sure that the script will find its datafiles after I move the whole directory. (The datafiles are in the same directory.) Here is a hack I invented to work around it: print(getwd()) source_pathname = get("ofile",envir = parent.frame()) source_dirname =

Hi all, I am using the "svm" command in the e1071 package. Does it have an automatic way of setting the "cost" parameter? I changed a few values for the "cost" parameter but I hope there is a systematic way of obtaining the best "cost" value. I noticed that there is a "cross" (Cross validation) parameter in the "svm" function. But I

For R v2.1.1 patched and R v2.2.0 devel: Calling source(file, chdir=TRUE) with is.character(file) != TRUE, that is, with 'file' as a connection, will generate an error. Example: > file <- textConnection("cat('Hello world\n')") > source(file, chdir=TRUE) Error in source(file, chdir = TRUE) : Object "ofile" not found Of course, it does not make

Hi all, Forgive me if this question has been addressed, but I was unable to find anything in the r-help list or in cyberspace. My question is this: is there a function, or set of functions, that will enable a script to detect its own path? I have tried file.path() but that was not what I was looking for. It would be nice to be able to put all the related scripts I use in the same folder with a

Hello, Is there a way to find where a script is located within a script? getwd() doesn't do what I want because it depends on where R was called from. I want something like source("randomFile") and within randomFile there is a function called whereAmI() which returns c:\blah\blah2\randomFile.R In perl there is a library called FindBin and $FindBin::Bin has the directory of the file

* Use `mktemp` instead of playing with date(1). * Use -f instead of removing the file every time. * "echo ERROR; exit 1" is what die() is for. * Some cosmetic renamings ('k' to 'comp' for compression etc). * Remove the MacOSX comment. It's not MacOSX specific, and it's not a problem anyway. The number behaves just right. * Remove the $((${size}+10)). It's

Hi, I just upgraded to 1.1.0 from 1.0.1 this morning on my OSF/1 machine. I now have problems with the following code: %E /tmp 43% R --vanilla Version 1.1.0 (June 15, 2000) ... > test2 <- function () { plot(runif(30)) ofile <- "/tmp/newfile.ps" dev.print(file = ofile) } + + + + + > > test2() Error in device(...) : Object "ofile" not found However, if

Hi all, I am trying to play around with the randomForest function for classification. I know its performance is great. I am currently using the default options. It has many options. How do I further tweak the options so that I can make its performance even better? What are the options that are mostly used? Thanks a lot! M [[alternative HTML version deleted]]

Hi, Is there a way to measure network bandwidth per process in CentOS Linux release 7.6.1810 (Core) using any utility? I was reading about nethogs but it does not have the option to run it in daemon mode so that we can take a look at historical data to figure out the process which was consuming high network bandwidth instead it is a good tool for Live monitoring. Please suggest. Thanks in

Hello, Below is a function (test.map) that permits drawing the same map using three different devices. The "pdf" device doesn't clip polygons to the plot region as I see it does by both the native device (in my case "Quartz") and the "png" device. test.map("pdf") # produces "test-map.pdf" with no clipping test.map("png") #

Hello everybody, I'm using hdf5 files to store results from intermediate calculations. These are usually part of a list, called "res". As I want the hdf-files to contain all the members of res in its top "directory", I used to do attach(res) do.call("hdf5save", args=c(fileout=file.path(dir, ofile), as.list(names(res)))) detach(res) which did what I

Hello all: I have a function that writes a fairly elaborate report based on some survey data. For documentation and bookkeeping purposes, I'd like to write out in the report the function call that produced the report, or at least enough information to help me recreate the steps that led to that report. I've been generating all the reports with scripts, in order to be able to recreate

Hi all, What parameter do I normally change in the rpart function? How do I set the "cp" option? Is there a way to read off error rate directly from the "rpart" function for training data; I imagine for testing data I have to apply a "predict", but for training data I guess the error count would be somewhere existing once the "rpart" function is

Hello, everyone. No need to read this message. I'm posting for documentation for other poor, ignorant slobs like me who are struggling to pull together the many technologies to make converged networks happen. Hopefully, this will help save someone else the time I spent. I started the below email until I realized I had solved multiple parts of a compound problem but not all at the same time.
