Hi, When I call the *switch* function first time, it works. but when I call it at the second time, it does nothing. The version I use is R version 2.9.0 Under development (unstable) (2009-02-21 r47969) here is the output: > organism="human" > species <- switch(organism, human <- "Hs", fly <- "Dm", mouse <-

Hi, Few days ago I have asked about spatial join on the minimum distance between 2 sets of points with coordinates and attributes in 2 different data frames. Simon Knapp sent code to do it when calculating distance on a sphere using lat, long coordinates and I've change his code to use Euclidian distances since my data had UTM coordinates. Typically one data frame has around 30 000 points

Hello to everyone, I am trying to compute a mean and show it to the screen and then save to later be used as a boxplot.I have used the following code: dat<-read.table(file="C:\\Documents and Settings\\Owner\\My Documents\\Yeast\\Yeast.txt",header=T,row.names=1) file.show(file="C:\\Documents and Settings\\Owner\\My Documents\\Yeast\\Yeast.txt") x<-dat[2,23:46]

Hello everyone, I am trying to subset a matrix with the following code: dat<-read.table(file="C:\\Documents and Settings\\Owner\\My Documents\\Yeast\\Yeast.txt",header=T,row.names=1) file.show(file="C:\\Documents and Settings\\Owner\\My Documents\\Yeast\\Yeast.txt") Z.matrix<-as.matrix(dat) Y<-array(dat,dim(,[46:63]) but I keep getting the error message: error in dim

Hi - When I'm trying to read in a text file into a labeled character array, the memory stamp/footprint of R will exceed 4 gigs or more. I've seen this behavior on Mac OS X, Linux for AMD_64 and X86_64., and the R versions are 2.4, 2.4 and 2.2, respectively. So, it would seem that this is platform and R version independant. The file that I'm reading contains the upstream regions

Dear R and Bioconductor Helpers, I am using a package called RankProd under Bioconductor to analysis my Y98 (yeast) microarray data. I had no problem following the example in the vignette but got stocked when I tried to analyze my own data. When I tried to run the following command, RP.out <- RP(rrf.sub, rrf.cl.sub, gene.names = y98.gnames, rand = 123) I got the following response: Rank

Dear R-enthusiasts, What a wonderful package R is, many thanks to all you have contributed (I've just started using it)...I have a few questions that I am having some trouble finding the answer to: I am using RPgSQL to grab some data from a postgresql database (about 179 columns and a few thousand rows), and I want to do a lot of pairwise comparison of the rows...(this is yeast genomic

Hello, I have a y-axis label that reads: "S. schenckii yeast cells". The part that reads "S. schenckii" needs to be in italic style, the rest of the text is normal style. How can I specify the different font styles for each part of the y-axis label? Thank you, Judith

Hello I am sorry fuch such a stupid question. Suppose I have a table of data having a lot of NAs and I want to replace those NAs by the mean of the column before NA replacement. How is it possible to do that efficiently ? Thanks in advance, Julie -- Julie Bernauer Yeast Structural Genomics http://www.genomics.eu.org

Dear cateGOry experts, hyperGTest documentation states that YEAST cannot be used as 'annotation' when evaluating gene ontology representation status for a given set of 'geneIds'. Because I am using a custom print I believe I need to create my own data package to use as the annotation file for 'annotation'. Can someone please describe how to make a data package that will

Dear R community Hope all of you are fine. I have a question regarding the an error message. Actually, I am trying to generate classification trees using "tree" package. It works well but for some datasets e.g., wine, yeast, boston housing etc. it gives an error message. Error in tree(V14 ~ ., data = training.data, method = c("recursive.partitioning"), : maximum

Dear R-expert, For histogram function, can we get the table of bin and frequency like in excel, together with the histogram? Therefore, we can check the number of data included. Thank you so much for your attention and help. ____________________________________________________________________________________ [[elided Yahoo spam]]

Well you can see that yeast is exactly weekday you have. The way out is to just not name the result toto <- function(mode) { ifelse(mode == 1, function(a,b) a*b, function(u, v, w) (u + v) / w) } ________________________________ From: Grant Izmirlian <izmirlidroid at gmail.com> Date: Sun, Feb 4, 2024, 10:44 AM To: "Izmirlian, Grant (NIH/NCI) [E]"

Hi, It's unfortunate that with recent revisions of R 2.13 (this appeared in revision 54640, March 2), 'R CMD build' now removes empty dirs in the package. People might have good reasons for having empty dirs in their packages. For example, in Bioconductor, we have some tools to automatically generate annotation packages and those tools are implemented in software packages that use

Thanks. Workarounds are interesting but... what's the point of the NOTE in the first place? H.

Is it possible to use R as a data-mining tool? Here's the problem I've got. I have a couple of data sets consisting of results from a cDNA microarray experiment - the details about the biology don't really matter here, the same theory applies for any other data-mining task (that's why I thought it'd be more appropriate to post this on r-user). Each of these datasets consists

Hello dear R users, *Here is the background for my question:* I just had a look at the help file for ? Yeast in the "HistData" package. In it, I found a small spelling mistake where the word "*c*istribution" was written instead (so I imagin) "*d*istribution". I thought maybe I should e-mail the developer. Since there is no link to contacting the developer inside

Just download Wbfs Manager 3.0 , trying to load it and it doesnt work , at first the icon wasnt right , add to change the permission details , now it looks like its trying to load but it isnt . Its the first program that im trying to load with wine so maybe im missing something or its because of the program ... http://wbfsmanager.codeplex.com/ If someone knows how to load it , some help would be

Dear Colleague, Happy New Year! As we know, codon preference among different species could be dramatically different. To enhance the expression level of a foreign protein in a particular expression system (E.coli, Yeast, Insect, or Mammalian cell), it is very important to adjust the codon frequency of the foreign protein to match that of the host expression system. One classic example is GFP
