Hi, I have a data.frame that contains a variable act which records the duration (in seconds) of two states (wet-dry) for several individuals (identified by Ring) over a period of time. Since I want to work with daytime (i.e. from sunrise till sunset) and night time (i.e. from sunset till next sunrise), I have to split act from time[i] till sunset and from sunset until time[i+1], and from time[k]

Hello, I'm trying to import into R files that contain data downloaded from logger devices as files with the following formats: .act .lig .trj .trn These files are essentially text files but use both tabs and commas as separators. I've tried the function scan: 1) scan("filename.act", what=character(0)) returns only two columns from the original 5 2) scan("copia.act",

My data frame shows changes on the variable act which records the consecutive duration (in seconds) of two states (wet-dry) over a few days for several?individuals (identified by Ring). Since I want to work with daytime (i.e. from dawn till dusk) and night time (i.e. from dusk till next dawn), I have to split act in two: from time[i] till dusk and from dusk until time[i+1], and from time[k] till

Hello, ? I have to create a new column from the values of other columns of a data frame. The new?column (y$n) is created imposing a condition (using a third variable y$h) that assigns the values of two time variables (y$b and y$timepos). Here's the piece of code to get there (using the attached files): ? xact <- read.table("act.lig", sep = ',',

Hi Adam, I hope this is what you wanted: dat1<- read.csv("example.csv",sep="\t",stringsAsFactors=FALSE) ?str(dat1) #'data.frame':??? 102 obs. of? 5 variables: # $ species? : chr? "B. barbastrellus" "E. nilssonii" "H. savii" "M. alcathoe" ... # $ period?? : chr? "dusk" "dusk" "dusk"

Hi, ? I'm trying to carry out Cramer von Mises tests between pairs of vectors belonging to a discrete distribution (concretely frequencies from 0 to 200). However, the program crashes in the attempt. The problem seems to be that these vectors only have positive integer numbers (+ zero). When I add a random very small positive decimal to the non-decimal part everything works fine (files prm1

Hi David, Thanks for your answer. Just to clarify, I would like to create 2 3 instructions put them in a function and execute them. Do you still think the JIT would be the best option?

Hi all, I'm trying to understand how the Module object works more in details, so suppose I've an empty module and I'd like to know if it is possible to add instructions at runtime and execute it. Is it possible to do it? Any suggestion on how? Thanks -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, does anyone know how to take the mean for a subset of observations? For example, suppose my data looks like this: OBS NAME SCORE 1 Tom 92 2 Tom 88 3 Tom 56 4 James 85 5 James 75 6 James 32 7 Dawn 56 8 Dawn 91 9 Clara 95 10 Clara 84 Is there a way to get

Hello,   I'd like to generate automatically all the possible combinations of a set of 8 variables (there are 535, too many to do it by hand). For example:   input: varA, varB, varC output: varA+varB+varC             varA+varB             varA+varC             varB+varC             varA             varB             varC Is there any function that produces this option?   Thank you [[alternative

Dear LLVMers, we have released a tool that uses LLVM to insert OpenACC or OpenMP 4.0 directives in programs. You can use the tool online here: http://cuda.dcc.ufmg.br/dawn/. Our tool, dawn-cc, analyzes the LLVM IR to infer the sizes of memory chunks, and to find dependences within loops. After that, we use debug information to translate the low-level information back into annotations that we

Hi I am just starting with xen and trying to get a few vm''s running on this pentium 4 system. I tried using virt-install to start things. I am using this link as the install base: ftp://download.fedora.redhat.com/pub/fedora/linux/core/6/i386/os/ , and a local file as hard drive. What happens is that virt-install downloads the kernel, boots, a VNC window for the new VM appears, but it

Hello, Are there any 'unallowed' (meta)characters that can cause R to parse a file incorrectly when using read.table? --Dawn Here the background if it's needed: I'm new to R, but have done some Perl. I'm trying to read in a data.frame from a file using * as a record separator. data <- read.table("all_genomes.data",header=T,sep="*") This has

Hi, I am trying to install R on the Unix system. When I type './configure', it seems many not installed on my computer. The last one is 'configure: error: No F77 compiler found'. Can you tell me where I can get these software before installing R? Thanks! Dawn [[alternative HTML version deleted]]

Folks: I am unable to get my opensolaris sn-b85 domU to start up in an opensolaris sn-b85 dom0. I am booted to xvm. Other systems, such as Fedora 8, WinXP Pro, W2k3 server, W2k8 server and Windows Vista startup normally. I have used the following to build the domU: # mkfile -n 25g /solhvm/solhvm.img # ls -l /solhvm total 269 -rw------T 1 root root 26843545600 Jul 7 10:37 solhvm.img

Hello - I am fairly new to R, (i.e., ability to create functions/write programs insignificant) and was wondering if there might be a convenient way to model the following: I want to fit a gaussian glm to grouped data, while allowing for unequal variances in each of the groups. More specifically, my data set looks something like this: ---------------- data group 1 76 1 2 82 1 3
