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

This must be a very simple question, but I can't find any information on it elsewhere, sorry. When extracting information from a list using column headers, how do I get R to interpret something as a variable rather than a string? For example: xx$"YAL002" works, but this doesn't: gene <- "YAL002" xx$gene neither do xx$parse(gene) xx$eval(gene)

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

Hi all, I'm trying to install an add-on package for R called RPgSQL. Its role will be to link R with a PostgreSql database. I work on a Linux machine. However, I'm quite a newbie as far as R's concerned, and I don't manage to install the package properly. That's the steps I followed : * downloading the package (archive) * R CMD INSTALL /path/to/package.tar.gz (as

Hi everybody I am trying to install RPsSQL and get the following error message: When I do ./configure form the untarred source directory I get loading cache ./config.cache checking for crypt in -lcrypt... no No crypt function found When I use the Package installer in R I get install.packages("/Users/christiaanpauw/tmp/RPgSQL/", , NULL, type = "source") Warning in

Hi. Currently, PotgreSQL binary for Cygwin is included in Cygwin's distribution. It is very stable working on my PC. But RMySQL and RPgSQL are not included in R contrib binaries. R's DB access will be faster by using these library than by RODBC? Please tell me whether will be available of RMySQL and RPgSQL in RWin binaries? Thanks. -------------- next part -------------- An HTML

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

Hi, i found tis message in the archive and have got the same problems ? John, perhaps you have found now a way install RPgSQL for windows2000, or anybody other ? many thanks for advance christian [SNIP] I wonder whether anyone has succeeded in building either the RPgSQL or the Rdbi.PGSQL and Rdbi packages for Windows. If so, would you be willing to share either the binary package(s) or

Hello, Using the RpgSQL package, there must be a way to get the row names into the table automatically. In the example below, I'm trying to get rid of the cbind line, yet have the row names of the data frame populate a column. > bentest = matrix(1:4,2,2) > dimnames(bentest) = list(c('ra','rb'),c('ca','cb')) > bentest ca cb ra 1 3 rb 2 4 >

I know this is something R isn't meant to do well but I tried it anyway :) I have this SPSS-datafile (size 31 MB). When I converted it to a R object with read.spss("datafile.sav") I ended up with a .RData-file which was 229 MB big. Is this considered normal? Then I tried to dump that object into a database with RPgSQL-package function db.write.table(object) (Memory ran out first

Dear list members, I wonder whether anyone has succeeded in building either the RPgSQL or the Rdbi.PGSQL and Rdbi packages for Windows. If so, would you be willing to share either the binary package(s) or instructions about how to set up the configure scripts? My preliminary efforts to get things going under Windows 2000 haven't met with much success. Thanks, John

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
