Could someone please point me to a source for the archives of this news group after June 21. I was subscribed to a digest version, but it stopped arriving after that date.

dum is a simple data frame transferred to Splus using the dump() command in Splus and the source() in R. All fields are numeric. There are no missing data. The data frame looks like it is should: > apply(dum,2,mode) yrcl sland s02 s234 "numeric" "numeric" "numeric" "numeric" > apply(dum,2,is.vector) yrcl sland s02 s234

Here is a simple example of what I would like to do: Given a data frame foo with variables x and fn. Suppose fn is a vector of characters which correspond to names of previously defined functions which have only one argument. I would like a vector returned where fn is applied to x foo <- data.frame(x=c(2,5,7), fn = letters[c(6,7,6)]) foo$fn <- as.character(foo$fn) "f" <-

I am comparing the Splus and R fits of a simple glm. In the following, foo is generated from rbinom with size = 20 p = 0.5. The coefficients (and SE's0 of the fitted models are the same, but the estimated deviances are quite different. Could someone please tell me why they are so different? I am using R version 1.3.1 and Splus 2000 release 3 on windows 2000. ++++++++++++++++++++++ foo

Could someone suggest a mail reader that will parse a digest from r-help into separate messages? Preferably, this reader would allow replies or forwards of separate messages. I use pine on a Sun running SunOS 5.7. If there were an add-on to pine that would accomplish this task, that would be even better. Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E.

Is there a way to put a legend on an xyplot -- eg, something akin to the key function? Or, is there a way to get the R legend function to work on a lattice plot? To the people who have done the work on lattice and grid: Thanks for making lattice. I'm finding it very useful. Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E.

The help for the round function states: round rounds the values in its first argument to the specified number of decimal places (default 0). Note that for rounding off a 5, the IEEE standard is used, ``go to the even digit''. Therefore round(0.5) is 0 and round(-1.5) is -2. Could someone provide a reference for this standard? Thanks, Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E.

Points, axes and axes labels on graphs printed from R are very light- almost unreadable. I am using the gui interface on the windows version to print the plot on the screen to an HP 8000 set as a postscript printer or PCL printer; the postscript output is light and the PCL output is very light. If I specify lwd =2 in the plot command, the lines are readable, but the points (open circles, in

The standard errors produced by predict.glm with type = "response" seem wrong. Here is an example using R 1.2 windows version along with the same problem in Splus. The standard errors for type = "link" are the same in both systems. R1.2> set.seed(10) R1.2> ytest <- 100*.95^(0:9) + rnorm(10,sd = 5) R1.2> ytest [1] 103.96964 97.60590 88.43220 85.90504

I am in the process of setting up R1.3.1 on a new computer running windows 2000. I am having problems running the PFE text editor simultaneously within R for editing functions and outside R for editing ordinary text files. The PFE editor behaves as I expected, if it is opened in R AND but no other PFE window is open outside R. Similarly, it also works fine if I am editing a text file outside

I've been trying to download from CRAN the floppy versions of the R source files: R-release-1.tar.gz, R-release-2.tar.gz I tried the servers in Seattle, Madison, and the Vienna Technical University. In each case, the file(s) were unavailable. Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E. York National Marine Mammal Laboratory Seattle WA 98115-0070 USA e-mail: anne.york at noaa.gov

Thank you very much for your help, your fuction runs on R without any change, and the results are the same that your obtain with Splus, but there still a small difference. In SAS W=0.960439 With your shapiro.wilk.test W=0.9606107 But the p-values are almost the same. Thank you very much for your help. > Here is a function for the Shapiro-wilk test that I obtained from StatLib. > Using

Full_Name: Wolfgang Huber Version: R-2.0.1 OS: HP-UX B.11.23 ia64 Submission from: (NULL) (81.104.215.6) Hi, I hope I am not missing something basic... I am using a somewhat exotic compiler and OS, but if I understand what I am seeing the problem is more general: In src/main/plotmath.c, the following function is defined /* Thickness of rules */ static double RuleThickness() { return

This is a followup to a recent post on using atop() to obtain multiline expressions. My reading of the plotmath docs makes it clear that issuing (in base graphics) the specification par(cex = 2) doubles symbols and regular text in subsequent plotmath expressions. However, it is unclear to me what specifying cex _within_ the annotation function using plotmath should do, and the following seems

I'm using R-2.6.2 on Fedora Linux 9. I've been experimenting with plotmath. I wish it were easier to combine expressions in plotmath with values from the R program itself. There are two parameters in the following example, the mean "mymean" and standard deviation "mystd". I am able to use bquote to write elements into the graph title like mu = mymean and R will

Full_Name: Murray H Smith Version: 1.7.1 OS: Windows2000 Submission from: (NULL) (202.36.29.1) This alleged bug is Windows specific and occurs when using Windows metafile plots. The problem does not occur in a Linux version. It does not occur in the pt rintout when a graphic is saved to a postscript file under Windows. The problem came to light when using plotmath to label a plot with

sorry, I forgot my sessionInfo: please see below. -------- Original Message -------- Subject: puzzled with plotmath Date: Thu, 20 Jan 2011 12:48:18 +0100 From: Claudia Beleites <cbeleites at units.it> To: R Help <r-help at r-project.org> Dear all, I'm puzzled with matrix indices in plotmath. I'm plotting matrix elements: Z [i, i], and I'd like to put that as label.

I am interested to use plotmath functions within a panel function but am having some problems getting the code right. Within each panel I am plotting the data, fitting a regression line, and would like to print the regression equation. Here is a trivial example of what I'd like to do: # generate simple data tmp.df <- data.frame(id = rep(1:4, each=4), time = rep(1:4, 4), das =

I hope to use the plotmath facility to print titles that mix math and values of R variables. The help for "plotmath" has an example, which after repeated reading, I find baffling. Likewise, I have read the help file for "substitute" (wqhich seems to be needed) without ever understanding what it does, other than being used in some magic incantations. I would like to do

Hello, I have a problem with the plotmath facility and haven't found any solution in the FAQ and Online-Help. I am trying to incorporate the value of a variable in an expression for an axis with plotmath. Considering having > gamma <- 10 I'd like to have a plot with > plot( .... , xlab=expression(gamma==10)) but depending on the true value of the variable. How can I
