t tests/ANOVA
I have a set of data that comprises genome numbers in single eggs from three different parasite clones - 3D7, HB3, and MIX. I can draw a boxplot of the genome numbers for each clonefed but how do I carry out a t test or ANOVA to compare if the means are signifcantly different? (Data is listed below) Many thanks, Georgina Humphreys clonefed genomes HB3 21.3 HB3 23.5 HB3 25.9 3D7 27.2 HB3 28.1

ANOVA
I have the attached data set (csv) and I want to run an analysis of variance on the wingsize data (comparing infected vs non-infected) within and between experiments. Can anyone help me with the command I should use? Many thanks Georgina PhD Student Division of Infection and Immunity B5-29, GBRC 120 University Place Glasgow G12 8TA Tel: 0141 330 5650

why results from regression tree (rpart) are totally inconsistent with ordinary regression
Hi, In my analysis of impacts of insecticide-treated bednets on malaria, I look at the relationship between malaria incidence and mosquito behaviors. The condensed data set is copied here. Ordinary regression (lm) shows that Incidence was negatively related to Mortality. This makes sense because the latter reflected the strength of killing mosquitoes by insecticide-treated nets. Since the

Mosquito Fixtures Won''t Load
I can''t get fixtures to load correctly in a Mosquito test. The first fixture loads in the unit test, but the rest don''t load at all. File structure: tracker/ tracker.rb test/ test_tracker.rb fixtures/ tracker_measurements.yml tracker_projects.yml Relevant test code: require ''rubygems''

spatially analyzing multiple data layers
Hi, I started using R about 3 months ago so please excuse my ignorance. I have two datasets. The first consists of 247 fixed position mosquito traps that were serviced weekly for 23 weeks. The second is dengue incidence data indexed to home address for the same time period. I would like to see if there is a space time relationship between mosquito catch rate and dengue incidence. So far I have

multiple logical streams
Hi, Why is seekability necessary in case of multiplexed multiple logical streams? Isn't the differentiation based on serial number sufficient to continue decoding of pages in the sequence of their arrival?

zero inflated poisson and censored-continuous models
I wonder if there is a package that will estimate a Zero Inflated Poisson Model (ZIP), and also if there is a package that will estimate what is called the Tobit model: that is a combination of censored and observed values in the same sample.

How to read NT Domain accounts from a Unix box
Hi, Is there any open way of reading user/group accounts of a NT Domain from a Unix box? I guess, rpcclient is more like a hack of MS protocol. Is it the only way currently? Can anyone give more information on this? Thanks in advance.

Spatstat - Several density plots using the same scale
Hi everyone, I am using the package "spatstat" for ploting kernel maps of my data. It is a marked point pattern, the result of mosquito surveillance in a area in a week. For each trap, the number of individuals captured is the mark of the point. > plot(density(X, weights=X$marks)) makes a nice kernel, but the problem is that I've got several weeks and for each week the density

A question on lmer() function
Dear R users, We have encountered a slight problem when using the lmer() function: 1. Data description: 11 locations; Nt: monthly mosquito population density from 1994-2005 in each location. 2. Question: to examine the degree of spatial heterogeneity in the system by testing model support for single versus multiple intercepts and slopes for the location effect. We applied the lmer()

Fibonacci
Hi! I am trying to work out the code to get a Fibonacci sequence, using the while() loop and only one variable. And I can't figure it out. Fibonacci<-c(1,1) while (max(Fibonacci)<500){ Fibonacci<-c(Fibonacci, (max(Fibonacci) + ?(Fibanacci))) } How can I tell R to take the value one before the max value? (Without defining another variable) (Probably super easy... I am a

ZFS core contributor nominations
The time has come to review the current Contributor and Core contributor grants for ZFS. Since all of the ZFS core contributors grants are set to expire on 02-24-2009 we need to renew the members that are still contributing at core contributor levels. We should also add some new members to both Contributor and Core contributor levels. First the current list of Core contributors: Bill

[LLVMdev] parallel loop metadata question
I propose that we change the first paragraph of http://llvm.org/docs/LangRef.html#llvm-mem-parallel-loop-access-metadata: --- For a loop to be parallel, in addition to using the llvm.loop metadata to mark the loop latch branch instruction, also all of the memory accessing instructions in the loop body need to be marked with the llvm.mem.parallel_loop_access metadata. If there is at least one

[LLVMdev] parallel loop metadata question
Will do. I will write something up. Hal, your concern below isn't so much with the proposed semantics but rather with the use - that optimizations must respect the loop for which the metadata applies, correct?

[LLVMdev] Proposal for ""llvm.mem.vectorize.safelen"
Yes, I think the 2 outcomes are: - the current spec is unclear and will be clarified - in order to support safelen() and even the simd construct itself, LLVM will require infrastructure work to know when a lexically backwards dependence may have been introduced.
