search for: aberration

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.

...I still have a gray desktop. If I move the cursor to the top left corner and it shows all the open windows, the desktop wallpaper / background shows just fine, but when I select any window/app, my desktop reverts to gray. I have tried resetting the desktop background but it does not remove this aberration. Any gnome gurus out there that can point me to the gnome foo required to get my desktop looking 21st century and not like my old monochrome Windows386 circa late 1980's. Thanks Rob

Hi. I have an object. I think it is a list. > str(corTFandPCA) num [1:922, 1:5] -0.0226 -0.0504 -0.0208 -0.0582 -0.0257 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:922] "abdomen.2" "abdomimal.3" "abdominal.4" "aberration.5" ... ..$ : chr [1:5] "PC1" "PC2" "PC3" "PC4" ...

...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 l...

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!

...o this? If I type:    div2 <- div1[is.numeric(div1)]    div2 I get    data frame with 0 columns and 1 rows OTOH, if I type    div2 <- as.numeric(div1)    div2 I get    [1]  9  4 15 16 18 20 17 21 21 18 24 24  8  8 NA Huh?? What do I need to do? The data in V8 in this particular instance is aberrational - I don't care how it gets treated; although I really want the number 46.36 out of it. Any sane solution will do, though. [[alternative HTML version deleted]]

I'm trying to test Samba4 as an AD style pdc. following the instructions at http://wiki.samba.org/index.php/Samba4/HOWTO at step 9 I get root at pdc:~# kinit administrator at MYDOMAIN.COM kinit: Cannot contact any KDC for realm 'MYDOMAIN.COM' while getting initial credentials root at pdc:~# and yet host -t SRV _kerberos._udp.mydomain.com gives _kerberos._udp.mydomain.com has

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. Any suggestions would be appreciated. John -------------------------------- John Fox, Professor Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604

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

If it was then it should be quite easy to point out the post(s) i...

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...

...where the repeated factors are the different models. For some reason, this "analysis of variance on 'variance explained' as data rings a bell as something not methodologically correct. On the other hand, R^2 may be distributed in a way that fulfill of the ANOVA assumptions. Is it an aberration? Thanks a lot in advance, -Jose

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,
