I am trying to upload into R 143 Affymetrix chips onto using R on the NIH Nimbus server. I can load 10 chips without a problem, however, when I try to load 143 I receive a error message: cannot create a vector of 523263 KB. I have expanded the memory of R as follows: R --min-vsize=10M --max-vsize=2500M --min-nsize=10M -max-nsize=50M (as specified in help in R). After running this command the

Hi, I change the dovecot.conf default_mail_env = mbox:/Mail/IMAP/%u/:INBOX=/var/mail/%u After I did the change, I restart dovecot with the hope that folder that I create will be stored in /Mail/IMAP/%u. Then I use Mozzila as my email client and change the IMAP server directory to ~nina/IMAP/ which is the link to /Mail/IMAP/nina/. But then I can not create folder anymore from Mozzila, or view

Dear R-users, I intend to do a spatial analysis on the genetic structuring within a population. For this I had thought to prepare a kernel density estimate map showing the spatial distribution of individuals, while incorporating the genetic distances among individuals. I have a dataset of locations of N unique individuals (XY-coordinates) and an NxN matrix with the genetic distances given as a

Hi, I am extracting data from a table where the rows have different column lengths, and empty columns have NA in them. Whenever I extract a row with some empty columns, the resulting vector carries all the NAs. Is there a way to ignore the empty columns? Thanks, -Nina

Hi, I have a CSV file where each row has at least 20 columns and some rows have up to 30 columns of data. When I use the command, Pathways<-read.table('MetaCycSample3.csv',sep=',',header=FALSE,quote='"') anything past the 21st column gets kicked down to a new row. How can I fix this? Thanks, -Nina

Dear R-users, I'm trying to recode a variable. After using cut(data.vector,breaks=my.breaks,labels=my.label) I need the data.vector to have the same values as the labels. To make it clear: x<-runif(10) y<-cut(x,breaks=c(0,0.3,0.7,0.9,1),labels=c(3,6,7,9)) as.numeric(y) returns something like a vector 1 3 3 2 2 1 4 2 3 4 . I need something like 3 7 7 6 6 3 7 9 6 7 9 for further use. I

Hello, I am a total beginner with ?R? and found a package ?venn? to create a venn diagram. The problem is, I cannot create the vectors required for the diagram. The manual say: "R> venn(accession, libname, main = "All samples") where accession was a vector containing the codes identifying the RNA sequences, and libname was a vector containing the codes identifying the

Hi, I have a CSV file with various biological reactions. Subscripts, superscripts, and italics are encoded in carats, and I was wondering if R can actually recognize those and print actual superscripts, etc. Here's an example: <i>S</i>-adenosyl-L-methionine + rRNA = <i>S</i>-adenosyl-L-homocysteine + rRNA containing

Hi I tried to install the sem package and it was succsessful but I keep getting the following message Paket 'sem' erfolgreich ausgepackt und MD5 Summen abgeglichen Die heruntergeladenen Pakete sind in C:\Users\Dean\AppData\Local\Temp\RtmpVRxlLZ\downloaded_packages aktualisiere HTML Paketbeschreibungen Warning message: In file.create(f.tg) : kann Datei

Hi, I know this must be a stupid question, and sorry in advance for being such a noob. But, is there way to get R to display only certain variables when running a script. I know if you want to see the value of a variable when using the interface, you just type it in and hit enter, but is there a command that I can use in a script file that will show the value at a certain point? Thanks, -Nina

Hello all, i am using Samba samba-3.0.23c_2,1 under FreeBSD 6.1 Release. The Problem is when i connect from a Windows XP Box to a share i have setup on the server and create a new File or Directory, i have to manually click Refresh or F5 to have the newly created File or Folder appear in the List. Does anyone experience the same thing, and how can i fix this? Thanks a lot, David Below

Hi, I have a data frame with strings that have two letters and four numbers. When I store a whole row as a new vector and try to remove the preceding letters using the gsub command, it returns characters of single numbers that have no relation to the numbers in each string. I also noticed that when I view the new vector before using gsub, it includes the original headers from the data frame. For

Hi, Sorry for the simple question. Is there a way to change the name of only one column of an existing data frame? I know colnames allows you to set the name of all the columns, but only one column in the middle of my data frame needs a new name. Thanks, -Nina

Dear list, sorry for bothering you with a probably simple question... I searched the archive but couldn't find the right answer. I have computed upper and lower bounds of a region and would like to plot them in a boxplot. My problem is now to get the two boxplots in the same graphic so that the boxplot of the upper bounds is directly on top of the boxplot of the lower bounds. The reason I

Dear List: I have a data frame prepared in the couting process style for including a binary time-dependent covariate. The first few rows look like this. PtNo Start End Status Imp 1 1 0 608.0 0 0 2 2 0 513.0 0 0 3 2 513 887.0 0 1 4 3 0 57.0 0 0 5 3 57 604.0 0 1 6 4 0 150.0 1 0 The outcome

Hello, I have a very simple question about "2 barplots in the same graph". It seems quite easy, but I searched google for long time, haven't find solution. For example, I want one graph like: x1=seq(0,2,by=0.3) x2=seq(3,0,by=-0.1) barplot(x1,col="red") barplot(x2,col="green") It means if it's on the same graph, some bars are overlaped. So if the bars are

I am doing a simulation with a relatively large data set (20,000 observations) for which I want to calculate the area under the Receiver Operator Curve (AUC) for many parameter combinations. I am using the ROC library and the following commands to generate each AUC: rocobj=rocdemo.sca(truth = ymis, data = model$fitted.values, rule = dxrule.sca) #generation of observed ROC object

I have the following problem: My data is a matrix of multiple columns and rows. The column I am interested in looks like that (I think it is a column in a matrix that contains a vector each?): [[1]] [1] A B C [4] D E [[2]] [1] A D E [[3]] [1] C E F [4] G I now want to look for a special word (for example C; in my case the single entries are words, not single letters) and return a vector, like

Dear R-users, another question concerning a persp()-plot: What does it depend on which line is labeled as an axis? Some plots I've done look fine, but in one plot, a different line is labeled. I can't find out why, as I just copied the code. Two small *.ps-grafics can be downloaded on http://www.math.uni-bremen.de/~nina/grafic.html to illustrate my problem. Thanks for your help in

Thank you for your replies so far. Sorry for bothering you again, but I'm still not able to get what I need as I don't understand all parts of the replies (just using R for easy things....). Is there a code for plane3d() like some of you sent me for points3d()? I was not able to get that out of the scatterplot3d package... What I can do is to get the x,y and z-range for the xlim,ylim and
