Hi the list, Is there a way to give a matrix to a C function, and then to use it as a matrix ? I write a function to print a matrix, but I use it as a vector : 1. void printMatrix(double *mTraj,int *nbCol, int *nbLigne){ 2. int i=0,j=0; 3. for(i=0 ; i < *nbLigne ; i++){ 4. for(j=0 ; j < *nbCol ; j++){ 5. Rprintf(" %f",mTraj[i * *nbCol + j]); 6. } 7.

I did some additional testing - I stopped Kafka on the host, and kicked off a disk check, and it ran at the expected speed overnight. I started kafka this morning, and the raid check's speed immediately dropped down to ~2000K/Sec. I then enabled the write-back cache on the drives (hdparm -W1 /dev/sd*). The raid check is now running between 100000K/Sec and 200000K/Sec, and has been for several

All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one. Here is an iostat example from a host within the same cluster, but without the RAID check running: [root at r2k1 ~] # iostat -xdmc 1 10 Linux 3.10.0-327.13.1.el7.x86_64 (r2k1) 05/27/16 _x86_64_ (32 CPU)

Hi You expect us to solve your problem but you ignore advice already recieved. Your data are unreadable, use dput(yourdata) instead. see ?dput > test<-read.table("clipboard", heade=T) Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : line 115 did not have 6 elements What is ?ideal interval? can you define it? Should it be such to provide eqal

Hey, i want to define 3 ideal breaks (bin) for each variable one of those variables is attached in the previous email, i don't want to consider quartile method because quartile is not working ideally for that data set because data distribution is non normal. so i want you to suggest another method so that i can define 3 breaks with the ideal interval for Recency, frequency and monetary to

Hej, i need the which() funktion to find the positions of an entry in a matrix. the entries i'm looking for are : seq(begin,end,0.01) and there are no empty spaces i'm searching in the right range. so i was looking for the results R can find and i recieved this answer. for (l in

is there a way to use the actual index value for plotting zoo objects this is the way that the index is set up and a sample range of what I would like to plot 01/01/06 00:00:00 - 01/01/06 23:45:00 { library(zoo) # chron library(chron) fmt.chron <- function(x) { chron(sub(" .*", "", x), gsub(".* (.*)", "\\1:00", x)) }} x <- structure(c(15.57, 15.5,

Hello every GNU's, I have a question about mt.plot, on multtest package. I'm wondering how do a plot with test like bonferroni, holm, hochberg,... and also résults of SAM(Significiance Analysis Microarrays) as we can see on several document of Sandrine Dudoit. Thanks a lot and Have a nice day Sandrine --------------------------------------------------------------------------------

Hi, I have to deal with a huge .txt table (~485.577 rows and 469 columns, > 1.5 Go file) I used the read.table function > tmp=read.table("data.txt", header=TRUE, sep="\t", fill=TRUE, na.strings="NA", comment.char="", stringsAsFactors = FALSE) However, I encounter troubles in interpreting some "\t" separator.. A column displays \t\t\t\t

Hi, I'm just wondering if it is planned to include the Lapack routine DGESDD (and friends) in R-1.4.0? This is faster (supposedly by a factor of ~6 for large matrices) than DGESVD which is currently (R-1.3.1) called by La.svd. And if it is not in the plans yet, is there a chance it could be? I've added it to my local version of R-1.3.1 and so far see a factor of 4 improvement over

Currently, if you were to print out the R frequently asked questions (http://cran.r-project.org/doc/FAQ/R-FAQ.html), it would be 132 pages long. Is it any wonder that so many question could be answered by looking at the FAQ but are not? Here are a few (contentious) suggestions to improve the document. * Remove the complete list of R packages * Include a complete list of frequently asked

Hi, This is the first time I've posted, and I apologize if I formulate this incorrectly. I am analyzing data from a multi-region carrot variety trial. 35 varieties of carrots were grown in 3 randomized complete blocks in organic and conventional fields in Wisconsin, Indiana, Washington, and California. In this example I am comparing the heights of the carrot tops at harvest. In other

Hello, I'm cc'ing R-Help. Sorry but your question was asked 3.5 years ago, I really don't remember it.

I'm struggling to find any help on this seemingly simple question - how does one read data with percentage (%) or currency (?,$ etc.) signs? When I try to read a data file which has any of those symbols in the data fields, they are read as characters rather than values. Is there a function or library which can deal with such values? As an example, I use this sample from one of chinna's

Hi, I am building a 64-bit R 2.0.1 on Solaris 9. The compiler is Sun Studio 8. Make was successful but I have a core dump during a make check. By the way, this problem also happens on my Solaris 8 machine though I did not get a core dump. I do not have 64-bit versions of the readline, tcl/tk, libncurses, etc libraries so these caused configure not to use them with ELFCLASS32 errors. I use

Dear R devel, Is libcurl support required to run R.devel, or is it optional?

Hi, I am studying Kalman Filter and it seems to be difficult for me to apply the filter on a simple ARMA. It is easy to construct the state-space model, for instance: dlmModARMA(ar=c(0.4,-0.2),ma=c(0.2,-0.1, sigma2=1) but applying the dlmFilter on it, it doesn't work... I don't know if my problem is clear but if anyone has already worked on Kalman filter, it could be great to advise me!
