I wanted to add some text to a plot and got (R-1.6.0, Linux): > text(x = c(1, 4), y = 5, labels = x) Error in text.default(x = c(1766, 1895), y = 5, labels = x) : Object "x" not found With the default value of 'labels': > text(x = c(1, 2), y = 5, labels = seq(along = x)) Error in seq(along = x) : Object "x" not found A scoping bug? :) But >

In the first line, use the dist function, found in library mva, to get the distance between each pair of rows. From this calculate an incidence matrix for which element i,j is true if row i in dat equals row j in dat (and false elsewhere). In the second line, for each row calculate the indices of the matching rows and take the minimum of those as the key. incid <-

I have a problem with some functions handling dates, in packages 'date' and 'survival' (they seem to be identical). For instance, from the documentation, -------------------- mdy.date {survival} R Documentation Convert to Julian Dates Description Given a month, day, and year, returns the number of days since January 1, 1960. Usage mdy.date(month, day, year, nineteen = TRUE,

Consider > oj <- data.frame(x = c(TRUE, FALSE, NA)) > oj x 1 TRUE 2 FALSE 3 NA > summary(oj) x Mode :logical FALSE:1 TRUE :1 But > oj$x <- factor(oj$x) > summary(oj) x FALSE:1 TRUE :1 NA's :1 My point is that NA's should be reported for logicals like they are for other data types. Göran --- Göran

I need to order a long vector of integers with rather few unique values. This is very slow: > x <- sample(rep(c(1:10), 50000)) > system.time(ord <- order(x)) [1] 189.18 0.09 190.48 0.00 0.00 But with no ties > y <- sample(500000) > system.time(ord1 <- order(y)) [1] 1.18 0.00 1.18 0.00 0.00 it is very fast! This gave me the following idea: Since I don't care

I find 'How do I convert factors to numeric?' in the FAQ (7.12), but not the other way around. Trivial maybe, but > codes(factor(c(2, 10)) [1] 2 1 > codes(factor(c(2, 9))) [1] 1 2 How do I get the levels attached to the codes in numeric order?

When reading an spss file, I get the following message: Warning message: ../totmorH.sav: Unrecognized record type 7, subtype 13 encountered in system file. What does it mean? Do I have to worry? The result looks as expected. I do not have (easy) access to SPSS, so I cannot check exactly that I got what I should have. Thanks, G??ran And, I'm using R-2.0.1 on Debian testing (from source).

I will be giving a course in survival analysis using R (of course!) for people who know nothing about the subject (including R), but know basic statistics. I'm looking for a suitable course book. Therneau & Grambsch (2000) is an excellent book, but too much for this course. I need somthing more elementary. I have a vague memory saying that such books exist, but I cannot find any for the

I have a data frame containing children, with variables 'year' = birth year, and 'm.id' = mother's id number. Let's assume that all the births of each mother is represented in the data frame. Now I want to create a subset of this data frame containing all children, whose mother's first birth was in the year 1816 or later. This seems to work: mid <-

Hello, I'm trying to use coxph() function to fit a very simple Cox proportional hazards regression model (only one covariate) but the parameter space is restricted to an open set (0, 1). Can I still obtain a valid estimate by using coxph function in this scenario? If yes, how? Any suggestion would be greatly appreciated. Thanks!!! [[alternative HTML version deleted]]

I'm looking for a Windows distribution of TeX that works with R, after a few years' absence from Windows.

I noticed the same thing as I reported below, when I upgraded from R-2.0.0-alpha-20040918 to today's beta version: 'R CMD check' failed as before; but after cleaning 'src' from .o and .so files, it worked again. So the two-day-old '.so' file is obviously different from today's. Has compiler directives changed in the two last days? Or what is happening? G?ran On
