Hi there, I recently switched to Mac and I wonder if there is any way to get the R console to autocomplete names of list objects or slots of objects. The command line version allows to type e.g. list$ and two times the tab button and then comes up with the names of the list objects. Same for slots of e.g. Eset objects like eset. Unfortunately this does not work in the Mac R console. Is there a

Hi! I would like to select probes (affy expression set) of genes that are "cancer-related". Conventionally the decision whether a gene is cancer-related or not is made by looking up the literature. Since this is not possible for all genes on the array I wonder if there is a way of doing this automatically? Best wishes Kristian -- _____ Dr Kristian Unger Imperial College London

Ok, I finally got the slideshow code to a state worth showing it off.

Hi All, I want to take a simple random sample from a large dataset, gly, but I'm getting an error message.

Quick question please....A user logs into windowsXP and tries to create a folder/document and the ownership on the new file/folder defaults to nobody:nobody. I have the user set up in samba on the IRIX machine. All other users have no problem. Anyone have any suggestions? Thanks Rachel

Hi All, I'm trying to automate a data summary using summary or describe from the HMisc package. I want to stratify my data set by patient_type. I was hoping to do something like: Describe(myDataFrame ~ patient_type) I can create data subsets and run the describe function one at a time, but there's got to be a better way. Any suggestions?

Hi there I have a problem with using Sweave in combination with the option driver = cacheSweave. Whichever code I try to run - when it comes to converting the tex file into pdf it comes up with the same errors (\csname \endcsname errors). Does anybody have an idea what it going wrong? > Sweave("pgfSweave-example.Rnw",driver = cacheSweaveDriver) Writing to file

Hi there Probably a very simple solution to this problem. I have a character vector eg c("name1","name2","name3") and I want to pull out these columns from a data.frame, converting each of these columns into factors also.

Hi, I am trying to create a function for a goodness-of-fit test for the Pareto Distribution for some loss data that I have. So far I have the following: function(X=OTOL) { n <- length(X)-1 #calculated the number of values (extra as 0 included) i <- 2:640 #values of i j <- 1:639 #values of i-1 Y <- (n-j+1)*((X[i])-(X[j])) #First part of GoF model Y } Where OTOL is the ordered loss

Hi All, I have a factor variable with 52 levels -with long, annoying names. I want to keep only rows with some variables. I can do this using this code: test1 <- subset(nih2009,ic_name %in% c('NATIONAL EYE INSTITUTE','Veterans Affairs')) dim(test1) [1] 2396 38 But this doesn't work: t1 <- subset(nih2009, ic_name %in% c(27,51)) dim(t1) [1] 0 38 I know

I have attempted to follow posting guidelines but I have failed to find out what I am doing wrong here. I am trying to use lines.survfit to plot a second curve onto a survival curve produced by plot.survfit. In my case this is to be a progression free survival curve superimposed upon an overall survival curve, but I will illustrate my problem using the example given in the help for

I''m a rails newb and have been Googling about this, but I''m still stumped. Not showing everything here, but basically it should be a pretty common setup so I''m sure others know what I''m doing wrong. - A meter can belong to many meter_groups - A meter_group can have many meters. - A user can ''subscribe'' to viewing a meter_group (Subscription)

Hi, I would like to view matrices I am working with in a clean, easy to read, separate window. A friend showed me how to do something like I want with edit(). I can view the matrix in the 'R Data Editor': For a sample matrix: > mat=matrix(1:15,ncol=3) > mat [,1] [,2] [,3] [1,] 1 6 11 [2,] 2 7 12 [3,] 3 8 13 [4,] 4 9 14 [5,] 5 10 15

Hi! Whenever I save a graphic in ps/eps format generated by filled.contour or image, an undesired grid is added to it (not visible on the X11 screen). For example: postscript("volcano.eps") filled.contour(volcano,col=gray(seq(0,1,,50)),levels=seq(min(volcano),max(volcano),,50)) dev.off() Any ideia how to eliminate this grid? Thanks, Rachel [[alternative HTML version deleted]]

I posted several months about the problem with adding tick marks to curves using lines.survfit. This occurs when lines.survfit is used to add a curve to survival curves plotted with plot.survfit. The help for this function implies that mark.time=TRUE thus: plot(pfsfit,conf.int=FALSE,xscale=365.25,yscale=100,xlab="Years",ylab="% surviving",lty=2,mark=3)

Hello, I am trying to deal with a database table that contains a date in the form of the number of seconds since epoch. Data is inserted in this format by an existing script that I can''t change, so a schema change isn''t realistic. I would like to allow humans to view and edit this data in the form of an actual human-readable date. I figured a facade column would be the

Hello, I was wondering if someone could tell me how I can make text dependent on a variable in a R function I have created. The function will create plots, thus I would like each plot to have a unique title based on the inputted variable as well as a unique file name when saved using the savePlot function. Thanks! Rachel
