Hi, I would like to simulate data with a binary outcome and a set of predictors that are correlated. I want to be able to fix the number of event (Y=1) vs. non-event (Y=0). Thus, I fix this and then simulate the predictors. I have 2 questions: 1. When the predictors are continuous, I can use mvrnorm(). However, if I have continuous, ordinal and binary predictors, I'm not sure how to simulate

Dear R-users, I haven?t found rules for logical operators. I need to select data according the following rule: Condition A & (Condition B | Condition C) How should I write it?? Is Condition A & Condition B | Condition C correct or will R execute (Condition A & Condition B) | Condition C ? Thanks for your help. Delphine Fontaine Delphine Fontaine Statistician Statistics

Dear Sweave-users, I want to print listing using sweave. Because my tables are very big, I use the longtable option. But, is it possible to recall the first line of the table (e.g the colnames line) on each new page ? Thanks for your help. Delphine

Does anyone know if for clinical studies the FDA would accept statistical analyses performed with R ? Delphine Fontaine

Hello, I am trying to translate a matlab program into R, and I have some problems to find out how to translate the PPVAL function. I know that ppval(pp,xx) returns the value at the points xx of the piecewise polynomial contained in pp( constructed by spline), but I don't know how to do the same thing in R. Thanks for you help Delphine

Dear R-Users, A message to continue the discussions we had in March and June. I have read the documents written since then (http://www.r-project.org/doc/R-FDA.pdf ; http://user2007.org/program/presentations/harrell.pdf ; http://user2007.org/program/presentations/rossini.pdf ; http://user2007.org/program/presentations/soukup.pdf) which are very interesting and useful.

Dear RGL experts, I haven't been able to add greek letters to my rgl plot3d. I have tried "expression" with no success. Here is the interested bit: > library(rgl) > cb <- cube3d() > plot3d(cb,xlab=expression(alpha),ylab="",zlab="",box=FALSE,alpha=0.5) The expression(alpha) appears as "alpha", rather than as a greek symbol. I suspect greek

Hi, Does any one knows how to include greek letters in plot labels and plot titles ? Thanks a lot paul --- [[alternative HTML version deleted]]

Hello all, I can't seem to figure how to use a greek character in expression() in plot() labels without adding a space. So for example below when plotting this out x<-1:10 plot(x,x^2, xlab=expression(Chlorophyll~italic(a)~mu~g~cm^-2)) the axis label read as μ g cm^-2 because I have space there with a tilda. But if I remove the tilda then my units are mug cm^-2. Can anyone recommend a

I would like to add the greek letter mu to replace u in my title shown below. main="R=[0.001uM]:A=[750uM]" i tried using main=expression(R=[0.001~mu~M]:A=[750~mu~M]) but this is not working at the moment. any help is appreciated thanks in advance [[alternative HTML version deleted]]

Hi, I desperately try to do s.th. like m=1.23455 sig=0.84321 plot(1,1) text(0.8,1,sprintf("<Sigma>=%1.2f?%1.2f",m,sig)) where actually the greek letter should appear for Sigma. I have tried all sorts of combinations with expression and paste etc. but could not work it out. Maybe someone has an idea and can help me. Thanks a lot+ Thomas

Hi, Does anyone have any ideas on how to show greek letters on the x and y axes? I have tried > plot(x,y, xlab=expression(delta), ylab=expression(gamma)) but the output on the x-axis is "d" and on the y-axis it is "g". Any help will be very much appreciated. Cheers, Sam.

Hi, I am having troubles in putting greek letters and formatted text in a plot m=1.43432 sig=0.124333 text(10.5,0.07,sprintf("<Sigma>=%1.2f±%1.2f",m,sig)) I would like to have the greek letter Sigma followed by the formatted numeric values of m and sig.

Hello there, Straight to the point: it seems that CairoPDF from package "Cairo" cannot handle greek letters from expression(). For example, > eta = seq(from=-pi, to=pi, length=100) > f = sin(eta)^2 > pdf(file = "temp_pdf.pdf") > plot(eta, f, type="l", main=expression(f(eta)==sin(eta)^2), xlab=expression(eta), ylab=expression(f(eta))) > dev.off()
