The on-line documentation for par() refers to a 'gamma' argument. However, if 'par()' is invoked, there is no gamma argument. -- Art Salwin salwin@mitretek.org (202) 863-2985 (202) 863-2988 (fax) --please do not edit the information below-- Version: platform = Windows arch = x86 os = Win32 system = x86, Win32 status = major = 1 minor = 0.0 year = 2000 month = February

The on-line documentation for the 'ann' argument under par(), states "If set to 'FALSE'...". However, this parameter shows up as a numeric on my machine, not as a logical. -- Art Salwin salwin@mitretek.org (202) 863-2985 (202) 863-2988 (fax) --please do not edit the information below-- Version: platform = Windows arch = x86 os = Win32 system = x86, Win32

The documentation for 'order()' has the following sentence: `sort.list' is the same, using only one argument put allowing partial sorting.

"An Introduction to R" notes that the function tapply() can be used to index a vector by multiple categories. But they don't show how to do this. How does one implement, for example, the example in the text in which tax accountants are indexed by both state and sex? Is there a way to use tapply() to put the vector into bins defined by the levels instead of having to exactly match

Here are some comments generated by a new R user based on initial experiences with the tool. On-line help for tapply: The following appears "for to each (non-empty) group of values" It seems there's an extra preposition in this sentence. On-line help for cut: "break" should be "breaks" morley.data not available with the distribution. Would be helpful for

Is there an R function that inputs a value and a vector, and returns the percentile corresponding to the value? Something like pvalue<-function(x,vector){mean(x>=vector)} but with interpolation. Given the above function, is there a way to do the following without the loop: for(i in 1:10) y[i] <- pvalue(x[i],vector) where x and y are numeric vectors of length 10? -- Art Salwin

This example is caused by R's messing with formula environments. That's explained in ?formula, but should it not be explained in ?model.frame ? Simple test: data <- data.frame(y=rnorm(100), x=1:100) testit <- function(formula) { weights <- runif(100) glm(formula, weights=weights, data=data) } testit(y ~ x) weights is looked for in the environment of the formula, not of

Dear all, I found that the new feature of the comment.char="#" argument in the read.table function truncated my data while the data set actually contains '#'. We analyze lot of data that contain '#'. This is really annoying and it is also not compatible earlier version of R. I searched the R archive and found the following message for the scan function. Is it

Hi to R developers. In the "Details:" section of "?levels", it would be nice including the following sentence, taken from a reply from Brian Ripley: If you set two levels to be the same label, they get merged. Granted, the "Examples:" section does have a terse comment and examples from which users may imply this behaviour. Yet, the documentation would be
