I need to reformat long data into a wide format (matrix for another program) but it does not seem straight forward. Can not seem to get it to work since some data elements are strings.

Hi Hadley et all, I am struggling with reshape2 and melt works and melt_check (filtered151) seems fine My cast command was acast (filtered151, Time ~ Species ~ Number) > melt_check (filtered151) Using time, Species as id variables $id [1] "time" "Species" $measure [1] "Number" When I execute cast the data matrix is in the correct order but the data

hello, i opened a bug on the ocfs2 bugzilla reporting difficulty i have utilize a different cluster stack than o2cb. link: http://oss.oracle.com/bugzilla/show_bug.cgi?id=1325 to summarize i'd like to use ocfs2 on an ubuntu server with drbd and ctdb. ctdb requires fcntl locks for its lock files. however o2cb doesn't provide that functionality whereas cman (redhat's cluster manager

hi guys, we're evaluating the available clustering options to get ctdb up and running for a highly available file server. we've set up both gluster and ocfs2 both on seperate 2 node setups. ocfs2 seems to provide better throughput and iops to samba clients than does gluster and that is comparing a single node server to a ctdb clustered 2 node server. problem with ocfs2 is that i've

Does anyone have suggestions about how to produce a map of British Colonial America 1775? At that time, Great Britain had 26 colonies in the Americas, including Bermuda, several Caribbean islands, "Quebec" (extending then almost to New Orleans), Nova Scotia, Newfoundland, Belize, and the 13 that declared independence in 1776. I've reviewed the "map"

Dear Rusers, I have met a difficult problem on explaining the differences of principal component analysis(PCA) between R,S-PLUS and SAS/STATA/SPSS, which wasn't met before. Althought they have got the same eigenvalues, their coeffiecients were different. First, I list my results from R,S-PLUS and SAS/STATA/SPSS, and then show the original dataset, hoping sb. to try and explain it.

Hello, I have a couple questions about removing rows from a data frame and creating a new data frame with the removed values. I provided an example data frame (d) below. Questions: 1) How can I search for "-999.000" and remove the entire row from data frame "d"? (all -999 values will be in sd_diff) 2) Can I create a new data frame "d.new" that only contains the

hello, i've set up a domain controller to replace a production server. both servers use profile redirection for all user environment directories. my problem is that when logging onto the new domain and server, windows will create in the %userprofile% local directory an Application Directory containing Microsoft/Credentials/*SID*, although a copy exists on the server. this directory is used

Dear useRs, I wrote a function that simulates a stochastic model in discrete time. The problem is that the stochastic parameters should not be negative and sometimes they happen to be. How can I conditionate it to when it draws a negative number, it transforms into zero in that time step? Here is the function: stochastic_prost <- function(Fmean, Fsd, Smean, Ssd, f, s, n, time, out=FALSE,

Hello, I want to find the parameters mu and sigma that minimize the following function. It's important, that mu and sigma are strictly positive. ----------------- optimiere = function(fmean,smean,d,x,mu,sigma) { merk = c() for (i in 1:length(d)) merk=c(merk,1/(d[i]^2)*(d[i]-1/(fmean*(1-plnorm(x[i],mu,sigma))))^2) return(sum(merk)) } ----------------- To do that I'm using the nlm

I''ve been lurking for a while, trying to figure out this traffic control stuff. We have 3 ADSL modems upstream, with 2, 2, and 1 megabit total bandwidth, 1/4 of it up, 3/4 down. We also have about 200 workstations downstream, connected through wifi. We are presently using tc to create about 200 buckets with HTB and SFQ. It seems like this is too many buckets, since usually only about

Hi all, I would like to set up an iterative read & write sequence to avoid reading and writing each file one at a time. Hundreds of data sets to re-calculate.? The code I have works well individually, but would like to set up an iterative read, calculate and write changing the input and output file names each iteration. I? think I have read that there is an R? feature using

How do people deal with R and memory issues? I have tried using gc() to see how much memory is used at each step. Scanned Crawley R-Book and all other R books I have available and the FAQ on-line but no help really found. Running WinXP Pro (32 bit) with 4 GB RAM. One SATA drive pair is in RAID 0 configuration with 10000 MB allocated as virtual memory. I do have another machine

Hi All, Anyone got this working with Samba? (3.5.4) I'm trying to install the driver, it copies across OK but then says "An unexpected error occurred in the print driver. Close the current driver window and retry the operation. 074:000:0061" Retrying doesn't help... The PS driver installs, but this lacks ALL of the options that come with the printer. Any help appreciated.
