I am trying to build a package (GWASTools, submitted to Bioconductor) that uses the "sandwich" package. I have references to "sandwich" in DESCRIPTION: Imports: methods, DBI, RSQLite, sandwich, survival, DNAcopy and NAMESPACE: import(sandwich) In the code itself is a call to vcovHC: Vhat <- vcovHC(mod, type="HC0") I have sandwich version 2.2-7 installed.

Dear all, I am forced to work in an environment without administrator rights. When using R2.13.1 on Windows 7 (64-Bit), I found that I can?t install or update any packages due to missing writing permissions. I managed to get full access to a directory on my C:\ drive now - but how do I specify that all libraries shall be installed into this directory? In Rcmd_environ I have the following

Dear all, Another newbie just got attracted to this mailing list. I am a biologist currently working my way through R, had sort play around with python earlier this year. I have some data exhibiting periodicity ** my data consists of peaks and valleys, with peaks arising due to the presence of a repetitive structural unit,** with x being a reference grid (position along a chromosome) and y

Hi, I'm new to this mailing list so apologies if this is too basic. I have confocal images 512x512 from which I have extracted x,y positions of the coordiates of labelled cells exported from ImageJ as a.csv file. I also have images that define an underlying pattern in the tissue defined as areas of different pixel values 0 or 255 (also 512x512) I've exported these images as .txt

Dear all, I need to make dendogram from read count in a csv file across 34 samples including biological replicate. Please share R code or package to do this. Do I also need to normalized read count before using read data? Thanks [[alternative HTML version deleted]]

I apologize for accidentally omitting some of the answers I got; here they are: ************** I use R regularly in my research in the pharmaceutical industry. I have used it for projects ranging from sample size and power curve estimation, analysis of laboratory data with mixed effects models, to analysis of mass spectrometry data. I have helped biologists here install and use it in limited

Dear All, With a colleague we are writing a paper where we show how R is a very nice tool to deal with some issues in the analyses of data in evolutionary biology. For the intro, I wonder if 1) Anybody has any rough idea of how many people might be using R or how many people have downloaded R, or similar (I am aware answering this question might require divinatory powers...). 2) Have/are any

Hello all, I am new to R but have some experience with MATLAB and am trying to make the switch. I generally find the two languages easy to adapt but there are a few routine tasks which I would like to run smoother in R and I am having trouble finding a help resource. Could someone suggest a guide to filtering, selecting, sorting, and processing biological matrix data? Here is a rudimentary

Dear All, have a general question about coefficients estimation of the mixed model. I simulated a very basic model: Y|b=X*\beta+Z*b +\sigma^2* diag(ni); b follows N(0,\psi) #i.e. bivariate normal where b is the latent variable, Z and X are ni*2 design matrices, sigma is the error variance, Y are longitudinal data, i.e. there are ni

We have a Windows 2000 PDC (domain name: DOM1) and a Windows 2000 CIFS fileserver (\\winfs) that we are migrating over to Samba (domain name: DOM2). Without turning off anything on the Windows boxes, I created a new PDC for the Samba server. I also created shares on this Samba server that closely match (same share name mounted off same NetApp backend) the Windows fileserver (e.g. \\winfs\share is

I designed out a mostly attribute driven database. Originally i was going to use PHP, but have now decided to use RoR. Being able to use the built in OR functionality would be nice, but I am not sure how well it melds with attribute dbs. If anyone can give me some pointers, I would really appreciate it (especially since this is my first endeavor and on an important project as well).

Hi everyone ! Could you please help me with this problem ? I??ve trying to write a code that assign to a variable the content from another, but all I??ve got is a message error. For example: if (age <=10) {group == 1} else if (age > 10 & age <= 20) {group == 2} else {group == 3} Syntax error Or if (age <=10) {group == 1} else (age > 10 & age <= 20) {group == 2}

Is there a weighted median function out there similar to weighted.mean() but for medians? If not, I'll try implement or port it myself. The need for a weighted median came from the following optimization problem: x* = arg_x min (a|x| + sum_{k=1}^n |x - b_k|) where a : is a *positive* real scalar x : is a real scalar n : is an integer b_k: are negative and positive scalars
