Hi, I have some very noisy, relatively sparse data; a biological response of roughly ~8 subjects at ~8 times points). I've been following the data trend using a lowess line, over-plotted with several values of bandwidth, 'f <- seq(0.3, 0.9, by=0.1)'. At this point, we have no models for these data. I wonder if there is any way under R to assign some sort of confidence interval to

I'm trying to find a clever way to re-map data from a database query into a data.frame. Querying a database often returns a table (data.frame) like this: GeneID MethodID Value 6 1 123 6 2 456 6 3 987 7 1 234 7 3 432 8 2 190 8 3 34 8 1 864 Note that GeneID=7 doesn't have a value for MethodID=2. Note that GeneID=8 doesn't have the

Hi, we are looking for a new workstation for big datasets/applications (easily up to 100'000 records and up to 300 Variables) using R. As an example: Variable Selection for a multivariate regression using stepAIC. What is the best configuration for a workstation to reach a high performance level for computing with R? Single core or multi core (is R together with nws package really able to

Hi, Thanks Kashyap for your answer. I am trying to give more data: virt-install invokation: # virt-install --name eff1 --disk /home/kvmimages/eff1.img --cdrom /home/kvmimages/Fedora-20-x86_64-DVD.iso --memory 4096 WARNING CDROM media does not print to the text console by default, so you likely will not see text install output.

To All How does one get a list of functions from a loaded package so that one can then get the appropriate help for each of the functions. Currently my method is based on a lot of trial-and-error. Here's an example of what I mean... >From this forum I learn that an interesting package called "multtest" exists on Bioconductor. I then use R Console's "Packages" --

Hi I have reinstall Fedora 20 from distrib. I have run yum update and yum upgrade.

Hello! I am trying to put two math expressions in the title of a plot. As you can see below, I can place correctly one expression at a time, but not both. Ideally I would like to have them separated by a comma. Any suggestions? > k <- 1 > n.eff <- c(20, 30) > ### this works > plot(0,0, main = substitute(n == k, list(k = k))) > ### this works > plot(0,0, main =

Two friend reported me a problem, which I can't solve: (I run R-1.0.0, Debian Linux) They hava a function "corr.matrix" (see end of mail), and when they create a 173x173 matrix with this function V <- corr.matrix(0.3, n=173) V1 <- qr.solve(V) reports: Error in qr(a, tol = tol) : NA/NaN/Inf in foreign function call (arg 1) For n < 173, qr.solve returns the correct

hi, - big and ugly mail. If you don't like them, delete it now :-) - I have collected and classified some information of: http://home.earthlink.net/~rwhron/kernel/bigbox.html And I observed that ext3 performance is worse than previous kernels(2.4.19...). -ac and -aa are here only as reference. Complete information is in the upper URL. dbench: Performance is worse. dbench (Numbers are in

Hi, Let me justify building R from source. While I can obtain R built for me under Ubuntu, I tend to build it from scratch as we use a NFS-shared build as well as shared R libraries for all the bioinfo staff at this company. Only one build and one set of packages to ensure uniformity across all workstations. My problem is that despite using a pretty standard build process, I am failing at the

Dear all, This problem came up initially while debugging a function, but it seems to be a more general problem of R. I hope I'm wrong, but I can't find another explanation. Let me illustrate with the raster package. For an object "RasterLayer" (which inherits from Raster), there is a method xyValues defined with the signature

R-helpers, I am hoping to find someone who uses both R and program Stata for GLMs. I am a beginner R user, finding my own way through; learning code etc. at the same time as learning the statistics I need to complete my project. What I have is the code from Stata and am trying to reproduce the same analysis in R - my program of choice. . glm count md ms rf sg, family(poisson)

In the course of exploring response prediction, I stumbled upon a small discrepancy between the CIs produced by predict.lm() and all.effects() require(mlmRev) require(effects) hsb.lm <- lm(mAch ~ minrty * sector, Hsb82) hsb.new <- data.frame( minrty = rep(c('No', 'Yes'), 2), sector = rep(c('Public', 'Catholic'), each = 2)) hsb.eff <-

Hi All, I am trying to use optim() to minimize a function with a penalty function term. This is a simple model bioeconomic model of a fishery. The penalty function constrains the amount of effort (f) at 9. This works fine. The code is: ********** nfleets<-2 M<-1 M<-array(M,dim=c(nfleets)) N<-1000 cost<-c(30,30) cost<-array(cost,dim=c(nfleets)) Price<-2

Hi, I have some values in a list format generated by the following: Path_Number <- 0010 ID.Path <- formatC(0001:Path_Number, width=4, flag=0) # Make vector of ID's. No_of_Effectors <- sample(1:550, length(ID.Path), replace=TRUE) # Define Number of Effectors each individual gets. Effectors <- split(sample(1:10000, sum(No_of_Effectors), replace=TRUE), rep(ID.Path, No_of_Effectors))

After an upgrade to Asterisk 12, I'm "collecting" channels.

Hello, I am trying to use the package "exams" to construct problem sets. I have constructed an exercise which generates a list of integers and asks the student to compute the median. rx is the vector of n numbers >str(rx) num [1:16] 21 9 8 18 4 12 17 2 9 7 ... I want to print out the entire vector as part of the problem. When I use \Sexpr(rx) only the first value (in this case
