All, I think this is pretty basic but I couldn't find the answer in any source. I have just built my own R for Linux (amd 64). It runs well, but R thinks that it only has 80 characters or so of screen width. I log on with Putty to the box and can stretch it as large as I want. Is there a simple way to tell R to use more screen width when displaying? From whatami: OS RELEASE :

We are new to R and evaluating if we can use it for a project we need to do. We have read that R is not well suited to handle very large data sets. Assuming we have the data prepped and stored in an RDBMS (Oracle, Teradata, SQL Server), what can R reasonably handle from a volume perspective? Are there some guidelines on memory/machine sizing based on data volume? We need to be able to handle

Greetings helpRs -- I would like to use plot() to plot two cumulative distribution curves so that a user of the plot can compare the distributions of the two variables. The following code draws two distributions separately, but I cannot find the instruction necessary to add a second cumulative distribution to the first one. Any suggestion would be very welcome. x1 <-

Hi, How can I overlap two density plots? A <- c(8,10,10,11,11,11,12,12,12,12,11,11,11,10,10,7) B <- c(11,13,13,14,14,14,15,15,15,15,14,14,14,13,13,10) plot(density(A)) plot(density(B)) Regards, Emre P.S. There's a overlap.density function in package DAAG Is there another way to do this? -- --- Emre ÜNAL http://www.geocities.com/dusemre [[alternative HTML version

Hi list, I have a question on how to identify the overlapped items from two vectors: >x<-c(0,1,2) >y<-c(1,2,2,3) and plot the number of the overlapped as well as non-overlapped in a diagram? Thanks much, Allen [[alternative HTML version deleted]]

Dear R Community, A simple problem (for some of you): I wish to index a data.frame by all elements NOT in my index E.g.: > a<-as.data.frame(matrix(rnorm(100),nrow=10,ncol=10)) > b<-which(a$V1>0.8) > b [1] 1 4 6 10 > a_indexb<-a[b,] > a_notIndexB<-a[!b,] > nrow(a_notIndexB) [1] 0 Indexing a on b is not a problem (a_indexb), but how can do get only the

Hi all, I have a data management question. I am using an panel dataset read into R as a dataframe, call it "ex". The variables in "ex" are: id year x id: a character string which identifies the unit year: identifies the time period x: the variable of interest (which might contain NAs). Here is an example: > id <- rep(c("A","B","C"),2)

Hi list, When exporting to PDF a graph with a legend, in the final PDF, the text is going beyond the legend box. > dev2bitmap("test.pdf", type="pdfwrite", h=6, w=6) The legend looks OK on the screen. I noticed that the size of the legend box depends on the size of the screen window, which is not the case for other graphical parts (text of the legend, title, axis

Dear R-helpers I would like to do a fit of the form: y = a (x+c)**b, where a, b and c are unknown. Does anybody know how to do it? Thanks Thomas

Hi! In a current project, I am fitting loess models to subsets of data in order to use the loess predicitons for normalization (similar to what is done in many microarray analyses). While working on this I ran into a problem when I tried to predict from the loess models and the data contained NAs or NaNs. I tracked down the problem to the fact that predict.loess will not return a value at all

Dear All: I do see I have weeks of codes in my console when I check with my arrow up keys. I have been clearing them with Control L but it seems to clear it clear the screen temporally. I do see the previous codes again when I open R the next day, after quitting the session! Q: How do I clear this? Thanks; YA -- View this message in context:

Dear list, Can somebody tell me how to invoke user-defined functions from script files during run-time? Basically I have (almost) one function per script file. I am thinking of something like #include in C++ import in Java/Python use in Perl No, I don't need my functions every time R is started. Neither I am thinking about writing building my functions into packages. I just

Hi all, I have a large data.frame, 1530 observation with 6 columns. I want to merge a 7th column, a transformation of the response variable (hospital admissions), namely trans<-sqrt(copd$admissions+0.25) trans<-data.frame(trans) And now when I do copd2<-merge(copd,trans) (copd being my original data.frame), R either crashes or is taking an extremely long time to do the computation. I

Hi, I was wondering whether there was an easy way to change the attributes of all elements in a data.frame (rather than looping through elements)? Specifically, I would like to set the "dim" attributes to NULL Thanks for any help, Jarrod -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

Hello, I have what I suspect might be an easy problem but I am new to R and stumped. I have a data set that looks something like this b<-c(2,3,4,5,6,7,8,9) x<-c(2,3,4,5,6,7,8,9) y<-c(9,8,7,6,5,4,3,2) z<-c(9,8,7,6,1,2,3,4) data<-cbind(x,y,z) row.names(data)<-c('a','b','c','d','e','f','g','h') which gives: x y z
