Dear R-users, I have sent another mail some hour ago about a matlab Code I was trying to translate in R. Actually I have found a simpler code originally written in S-PLUS for the same function. Author's page -> http://math.bu.edu/people/murad/methods/locwhitt/ ============================================================= rfunc_function(h, len, im, peri) # h -- Starting H value for

Greetings -- coming from Python/Ruby perspective, I'm wondering about certain features of R as a programming language. Say I have a huge table t of the form run ord unit words new 1 1 6939 1013 641 1 2 275 1001 518 1 3 3314 1008 488 1 4 14154 1018 463 1 5 2982 1006 421 Alternatively, it

I want to create a neural network, and then everytime it receives new data, instead of creating a new nnet, i want to use a backpropagation algorithm to adjust the weights in the already created nn. I'm using nnet package, I know that nn$wts gives the weights, but I cant find out which weights belong to which conections so I could implement the backpropagation algorithm myself. But if anyone

Hi, on 2 different servers, running 7.1-stable + zfs, I get this error rather frequently: Feb 5 17:01:03 warhol-00 kernel: impossible packet length (543383918) from nfs server sunfire:/dist Feb 5 17:01:03 warhol-00 kernel: impossible packet length (1936028704) from nfs server sunfire:/dist Feb 5 17:01:03 warhol-00 kernel: impossible packet length (1869363744) from nfs server sunfire:/dist

Dear R-core Team, As Thomas Lumley pointed out in one of his e-mails one can use commandArgs() to get a copy of the command line arguments supplied when R session was invoked and then use grep to extract parameters of interest. His solution works very well if the custom options are passed by names, e.g. --my-option=value, but what if one wants to pass parameters by their positions. Then it's

A couple of weeks ago I asked how it is possible to run an R script (not a function) passing some parameters. Someone suggested the function "commandArgs()". I read the on-line help and found no clarifying example. Therefore I do not know how to use it appropriately. I noticed this function returns the pathname of the R executable which is not what I need. I meant to ask if it is

Hey, I'm generating a .jpeg file for a web application passing parameters to R via cgi. R gets the parameters by using commandArgs, which are passed to a variable named j and z j<-commandArgs()[3] z<-commandArgs()[4] Later I want to use the characters strings of the argument which the variables are holding for my filename, e.g.: jpeg(file="d:/data/images/jz.jpeg",...)

Dear R experts: I am a bit stymied by how the argument picking-off works in R batch file usage. $ cat commandArgs.R cat(" Command Line Arguments were ", commandArgs(), "\n"); $ /usr/bin/R CMD BATCH commandArgs.R --args 1 2 3 $ /usr/bin/R --args 1 CMD BATCH commandArgs.R ... I am now getting into interactive mode ?! I guess it really is skipping the rest of the command line

Hi, I have a bunch of R scripts which have the hash bang !/usr/bin/env Rscript and I typically run these scripts by passing in some parameters like this: ./nameOfRScript arg1 arg2 ... I know Rscript has the option to run in --vanilla. Where exactly do I insert the --vanilla option? When I do something like this: ./nameOfRScript --vanilla arg1 arg2 ... And I try to access the commandArgs,

Hi, I'm currently trying desperately to get the nnet function for training a neural network (with one hidden layer) to perform a regression task. So I run it like the following: trainednet <- nnet(x=traindata, y=trainresponse, size = 30, linout = TRUE, maxit=1000) (where x is a matrix and y a numerical vector consisting of the target values for one variable) To see whether the network

Hi Vinod, Bjorn, Patrice, This patchset adds support for the Flexible Direct Memory Access (FDMA) core found on STi chipsets from STMicroelectronics. The FDMA is a slim core CPU with a dedicated firmware. It is a general purpose DMA controller supporting 16 independent channels and data can be moved from memory to memory or between memory and paced latency critical real time targets. After quite

Good afternoon all - While making a steady progress in learning R after Matlab I encountered a problem which seems to require some extra help to move over. Basically I want to merge a data from biological statistical dataset with annotation data extracted from another dataset using an 'id' crossreference and write it to report file. The first part goes absolutely fine, I have merged both

Hi, we have SunFire X4140 connected to Dell MD1220 SAS enclosure, single path, MPxIO disabled, via LSI SAS9200-8e HBA. Disks are visible with sas-addresses such as this in "zpool status" output: NAME STATE READ WRITE CKSUM cuve ONLINE 0 0 0 mirror-0 ONLINE 0 0 0

I was on vacation the last week and wrote some code to run a 500-day correlation between the Nasdaq tracking stock (QQQ) and 191 currency pairs for 500 days. The initial run took 9 hours(!) and I'd like to make it faster. So, I'm including my code below, in hopes that somebody will be able to figure out how to make it faster, either through parallelisation, or by making changes. I've

I would like R CMD build to run some R code which does some stuff and save the result as a file in /inst/docs folder. Is there any way of doing this. Thank you.

Hi, $ cat commandArgs.R args=commandArgs(trailingOnly=TRUE) args[1]+10 I have the above code. But the following command line gives me an error. I am wondering what is the correct way to convert a string to a vector? $ Rscript commandArgs.R 1:3 > args=commandArgs(trailingOnly=TRUE) > args[1]+10 Error in args[1] + 10 : non-numeric argument to binary operator Execution halted Regards, Peng

Dear Rui, >From my understanding of time-dependent covariates (not an expert but have been working on a similar problem), it would appear that the coding of the status column is not correct. Unless you have observed an event at each interval you should only have status=1 for the last interval. In your example I see 3 in total. Also, I think that if "end" is proportional to your
