I have just spent a day trying to determine why I seemed to be unable to read a file of microarray expression results into R properly. The file was produced by the Dchip software developed by Li and Wong at Harvard's Department of Biostatistics. It contains rows of tab-delimited fields in the order Probe set identifier Probe set description Array 1 expression Array 1 call Array 2 expression

Hi! I have a problem of curve fitting. I use the following data : - vector of predictor data : 0 0.4 0.8 1.2 1.6 - vector of response data : 0.81954 0.64592 0.51247 0.42831 0.35371 I perform parametric fits using custom equations when I use this equation : y = yo + K *(1/(1+exp(-(a+b*ln(x))))) the fitting result is OK but when I use this more general equation : y = yo + K

Hi, A64 versus A32/T32 code generation is controlled by the -target option which I don’t believe is under discussion here.

Hi Just stumbled into a problem with my recent new build C7 work station. Fully updated, gnome desktop, all was working well until I had a play with Tweak Tool, I wanted to try some other themes for window layouts as the default seems to not show check boxes correctly in all situations. I haven't yet determined what is causing this but suspected another theme may work better, as not being

...some nonstandard data set which I would like to plot but don't know how to do it in R. The data is in a matrix where the rows represent samples and the columns represent locations. The entries of the matrix are 0's and 1's, where 1 represents an event and 0 represents a non-event. e.g. aberrations <- matrix(rbinom(1000, 1, 0.8), nrow=20, ncol=50, dimnames=list(c(paste("sample",1:20,"")), c(1:50))) In addition, consecutive 1's in a given sample represents intervals of events. With this matrix I would like to produce a plot with the samples on the y-axis and the lo...

Hello all, I have a seemingly simple question which I have searched for an answer for for a few hours without luck. I have a matrix of both values and characters with thousands of rows. I would like to run a search of this matrix for certain values and would like the search to retrieve the entire row. How would I accomplish this? Thanks!

I am scraping data from a web page using XML (excellent package BTW - that's scraping data the easy way!). So far, I've got the code: tables <- readHTMLTable(theurl) rhf <- tables$tabResHistFull div1 <- rhf[which(rhf$V1=="Div ps"),] div1 which is giving me the result:        V1 V2    V3    V4    V5    V6    V7          V8    V9   V10   V11   V12   V13   V14  V15 15

Dear r-helpers, I wonder whether, given the "#rrggbb" representation of a colour, there is a simple way to select the complementary colour, also expressed as a "#rrggbb" string.

Hi everybody, I'm a new R french user. Sorry if my english is not perfect. Hope you'll understand my problem ;) I have to work on temperature data (35000 lines in one file) containing some missing data (N/A). Sometimes I have only 2 or 3 N/A following each other, but I have also sometimes 100 or 200 N/A following each other. Here's an example of my data, when I have only small gaps

Hi, I eventually installed three Debian unstable machines, so I could install the GlusterFS 3.3 beta3. I have a question about the self-heal daemon. I'm trying to get a volume which is replicated, with two bricks. I started up the volume, wrote some data, then killed one machine, and then wrote more data to a few folders from the client machine. Then I restarted the second brick server.

Context: R version 2.7.1 (2008-06-23) I don't know when this was upgraded in the department, I just ran into the aberrent behavior today. Problem: Our group BY CHOICE does not change character variables into factors by default. I can get into a long arguement as to why later, and will give one example of why below. The default behavior of S, Splus and R has been to create

Hi, I am currently using the aCGH package in R version 2.1.0 Windows with some supporting packages (eg. cluster) built under R 2.1.1.Using aCGH package, I am able to identify regions of genomic aberrations in my cell lines using the HMM model. However, when I tried to use aCGH for my paraffin embeded tumour sample, I got the following warning. Warning: MAD could not ben computed for one of the samples. I had used the same R commands for both my tumour samples and cell lines. I had performed HMM...

Dear all, This may seem obvious for some of you, but it got me thinking. Can one use correlations (or R^2) as data for an ANOVA? The case in hand: I have several models fitting the same data (individual fits per subject). The different models fitting the same guy will produce different R^2, I was wondering if these could be used as dependent variable in a repeated measures design where the

I'm running samba4 from git (latest as of sep 1) on ubuntu 10.4. It's operating as a PDC, as well as hosting a shared drive. The last couple days I've noticed that my shared drives will appear as disconnected, and indeed trying to connect to the server times out. If I look on the server, there are many (50ish) samba processes all sitting there sleeping. If I use the init script to

I have 1 samba4 server setup as a domain controller for FOO.COM. I want to add a second for redundancy. I really don't want to mess this up, and I can't find a clear guide online. Can anyone tell me the proper commands? Thanks. -Aaron

Hi there, I use the surf.gls() function to fit a variable measured over a surface. When I plot the predicted surface, there are local minima/maxima in almost every coordinate where data were measured, which seems aberrant. For instance: ?? x <- c(343,293,343,243,293,343,443,543,593,243,293,343,393,443,493,543,593,143,193,243,293,343,393,443,
