Has anybody written an actuarial (life) survival procedure, this does not appear to be an option in the survival package? This approach is common in orthopaedic surgery to demonstrate the survival of prostheses. I need to apply the "modified" lower conf.int because of the censoring over time. I want a life table which I can then easily plot. Many thanks

R Version 1.9.1 (2004-06-21) Mac OS X.3.5 Dual 2GHz PowerPC G5 GUI = "AQUA" I have a data.frame comprising percentiles with the column headings containing % characters, e.g. > (pp <- colnames(temp2)) [1] "5%" "10%" "25%" "50%" "75%" "90%" "95%" I use xtable to convert the data.frame to Latex but I want to

I have used polygon() to mark the confidence limits of a survival curve. In another project, I have used the col parameter to fill my boxplots. The poly() description refers to filling but actually produces hatching (i.e. lines ). boxplot() does truly fill the boxes with a colour or shades of grey (e.g. col="red"). My novices perception of R graphics is: If you can hatch it, you

Hi, Please, is out there anybody using RMySQL under Mac OS X? I'm trying to build it without much success. How must I add/locate mysql.h and lmysqlclient library? Thanks for your help, Ricardo -- Ricardo Rodr?guez Your EPEC ICT Team

Hi I would like to analyse an ordinal categorical variable. I know how I can analyse a nominal categorical variable (with multinom or if there are only two levels with glm). Does somebody know which command I need in R to analyse an ordinal categorical variable? I want to describe the variable y with the variables x1,x2,x3 and x4. So my model looks like: y ~ x1+x2+x3+x4. y: ordinal factor

Hi, If I have: foo <- survfit(y ~ x) where y is a survival object and x is a n-level factor. The documentation says when I plot(foo), the confidence intervals will not be plotted (which I guess is understandable as otherwise the plot will get really messy). I tried to plot with confidence intervals by using: plot(foo, conf.int = TRUE) and indeed the resulting plot is messy. However

Dear All, I've been using R for windows for a while, without too many problems. However, I'm forced to use the MAC OS system for teaching, because our teaching labs are mac only (not my idea!!). I have a very basic problem, but one that doesn't appear on the FAQs. I simply want to import data from a spreadsheet. I'm using exactly what works fine on Windows, namely: 1 save

There seems to be something different about pdf files generated under RAqua (1.8.1). I am losing text. I am not sure when things changed but, on Carbon 1.7, when files were 'drag and dropped' onto another application they worked fine. Now the text is lost but the graphics are intact. However the text is there when viewed with Acrobat. On the other hand, if I output to an eps file and
