Dear All, We have two computational biology positions to advertise - details below: Crispin ---- The Paterson Institute for Cancer Research (www.paterson.man.ac.uk<http://www.paterson.man.ac.uk/>), an Institute of The University of Manchester, seeks two (one senior, one junior) computational biologists to join the Applied Computational Biology and Bioinformatics Group (ACBBG). The

Manuel: I changed your variable names from x to 'long' and y to 'lat' on the riqueza_out.csv file. The code below should do what you want. Also, since the legend title is kind of long, I broke it down into three lines so you can see more plot area. I am cc'ing the other groups so more people use it if needed. library(rgdal) library(ggplot2) library(sp) library(maptools)

Hi: I am using Sweave and texi2dvi to generate a LaTeX document but can't find the way to hide the graphics while the R chunks are being executed. I thought results=hide would do it but that't not the case. If I do: \begin{figure}[h] <<figA=true,echo=F,fig=T,results=hide>>= a < rnorm(1000) plot(a) @ \caption{Weekly estimates.} \label{figure:ggplot1} \end{figure} The

Hi, I hope you don't mind me posting this to the list: We are seeking a postdoctoral scientist to join the Applied Computational Biology and Bioinformatics group at the Paterson Institute for Cancer Research. The role will be to develop novel approaches for the analysis of high throughput genomic data, such as those arising from Affymetrix microarray experiments. We are an

Hi Experts, As i am a new in this forum, let me introduce myself:- i am Debaranjan, from India, Assam.

Dear List I am using R with mcgv package to model spatial variation in density estimates of dorcas gazelle in Sinai. I have 59 points of data and 4 explanatory variables(distance from mountain edge, camel presence, Latitude & Longitude). I want to test the model fir via bootstraping. I have used the jacknife bootstraping but it have the limitation of allowing only 58 trials. I tried to use the

Hi- I'm a biologist trying to figure out the growth rate of salamanders in different ponds. I collected individuals from various populations at different dates, and using the size and date collected, I want to figure out the growth curve of each population. My question is: How do I fit my data to a Gompertz function in R? Thank you so much! Sarah -- View this message in context:

I''m a slow learner when it come to shortcuts and i got real tired looking up Textmate''s Rails snippets & commands in the context menu. So i fired up trusty OmniGraffle and quickly created a little Cheat Sheet for all default snippets/macros/commands in Textmate''s current Rails Bundle. Certainly helped me to remember these quickly. So, if you''re

I am starting to use R for almost any sort of calculation that I need. I am a biologist that works in the states, and there is often a need to convert from standard units to metric units. Is there a package in R for this already? If not I believe that I am going to write some of the most often used in function form. My question is should I include this in my StreamMetabolism package. It is

Hi all, The survivals functions can be tested by the Log-rank test and others, for example the Gehan-Breslow. The graham breslow work with the alpha values. But I don't know how is the Gehan-Breslow test with R. Somebody know a type function?.. or other suggestions? Any help will be really appreciated Jos?

Dear R Users, In the expresso function, which combination of these methods for data pre-processing (when using affymetrix oligo arrays) is the best: bgcorrect.metod = rma rma2 mas normalize.method = qspline quantiles loess pmcorrect.method = pmonly subtractmm mas summary.method = liwong avgdiff medianpolish mas There are many options within each method. I would appreciate a hint on the best

I installed R-2.9.0 yesterday, and followed the instructions in the R for Windows FAQ, 2.8 What's the best way to upgrade? It reads "run update.packages(checkBuilt=TRUE, ask=FALSE) in the new R and then delete anything left of the old installation." I did this but it returned an error. It's the checkBuilt=TRUE which causes it, though I don't know why: leaving it out or

Dear all, I am a biologist. I have two sets of distance P(start1, end1) and Q(start2, end2). The distance will be like this. P ------------------------ Q ---------------------------------------- I want to know whether P falls closely to the right end or left end of Q. P and Q are of different lengths for each data point. There are more than 10000 pairs of P and Q. Is there any test or

Hi, I am looking for a R package to draw 3d plot. But not in a static way like scatterplot3d or stuff like that. I would like to make rotate the plot, to zoom/unzoom etc..., actually to render the graph 'dynamic'... (for the biologist and bioinformatician, a R package which permitts to reproduce what pdb viewer does). Does a Way exist to do something like that in R ? Thanks,

Hi, I'm a biologist, so please forgive me if my question sounds absurd! I have 3 parameters x1, x2, x3 and a response variable y.The sample size is 75. I tried to do the following: mylm<-lm(y~ x1 + x2 + x3, data="mydata") but i can only get stats from anova for the first 2 variables. The third comes up as NA. The degrees of freedom for the third variable are 0. Is there
