Dear R-users, The numerical integration example given in Gentleman and Ihaka (2000), "Lexical Scope and Statistical Computing," JCGS, 9, 491-508, is very interesting and helpful in understanding how lexical scope is about. However, I got some questions that I just can't figure out. First all, allow me to copy the two functions given by the authors: midpoint <- function(f, a,

Dear R and ESS users, I got the following error when trying to load a source file (smart.R in directory E:\R\) into XEmacs through the menu iESS and "Load source file": Error in file(file, "r") : unable to open connection In addition: Warning message: cannot open file `E:Rsmart.R' It seems the slash "/" or "\" being missing, but I don't know

Dear R-friends, After change (and saved) font style to "bold" in GUI preferences from menu-bar Edit, R 1.2.0, Win98, the "buflines" in the file Rconsole changed to "bufiles" and that causes error in invoking R next time. Is this a bug? Merry Christmas & Best regards, C. Joseph Lu Department of Statistics National Cheng-Kung University Tainan, Taiwan

Please forgive me if this has been asked and answered, since I just can't find out. As I try the example given in the help page of xyplot() as follows: > library(lattice) Loading required package: grid Attaching package `lattice': The following object(s) are masked from package:base : levels > data(quakes) > xyplot(long ~ lat , data = quakes) R crashed!

Dear R users: How can I use panel.qqmathline, in package lattice, to add straight lines onto the plots generated by qqmath? I read help pages of qqmath, panel.qqmathline, xyplot, ..., but just can't one example that shows how to make it work. For example, > data(sleep) > qqnorm(~ extra | group, data=sleep, aspect=1) how can I use panel.qqmathline? Thanks very much for your help,

Dear R-friends, When I selected "Save as postscript" via mouse left-button on the active "R Graphics" window, those colored lines I made in the plot changed in the saved postscript file, e.g., color blue becomes green, red becomes blue, ...

Since I just experienced another crash on R 1.4.0 for Windows (this time is on plot(x, y) after using gls() of package nlme) and am told (thanks Andy) that is might due to the "official" version of binary copy. I am also told that "The one provided by Prof. Ripley is known to work. This has been asked several times on the list." Then, I am wondering when the

Dear R-friends, I have whole bunch of objects, say, A, B, ..., Z, all of them are "list" and haveing "Title" (a character string) as their first element. E.g., > A$Title [1] "Airplane Component" What I like to do is to find a way to printout all the Titles at one time. I tried the following: > paste(LETTERS, "Title", sep="$") ->

Dear R-Friends, Sorry to bother everyone with my earlier question: "Do we have similar R function to work like Minitab's INDICATOR?" I found the way to make things work: e.g., > x <- c(2,2,5,3,6,5,NA) > model.matrix(~ factor(x) - 1) factor(x)2 factor(x)3 factor(x)5 factor(x)6 1 1 0 0 0 2 1 0 0 0

Dear R-friends, As the binary windows version of R being distributed, what is the correct way to install contributed packages without using winst.exe as before? The answer in "R for Windows FAQ" says: "You can install pre-compiled packages either from CRAN or from a local .zip file by using install.packages: see its help page." But the information available in

Dear R-Friends, How can I calculate a double integral like \int_a^b \int_c^y g(x, y) dx dy where a, b, c are constants, g(x, y), e.g., g(x, y) = tan(x + y). I tried to nested integrate() and adapt(), but none of them working, seemingly due to the limits can not be specified constants. Best regards, C.

I'm switching from OpenLDAP to the newly released Fedora Directory Server (formely known as the Netscape Directory Server) as a LDAP backend for my Samba domain. I'm now faced with a problem regarding how Fedora DS handles the userPassword field. Unlike OpenLDAP it encodes it in base64 so instead of reading userPassword: {SSHA}0lP+r3Z1NVan7Caf4CG9oSgnTbQRrv/p it reads: userPassword::
