Let me first admit: I am experiencing this bug on a precompiled binary of R for windows, and I know these are not supported. I am not asking for support, but I thought the R developers would want to know about this. # Define: foo.page <- function(x) x # Then, foo.page("a") # actually invokes the pager (!) on object named "a" (if one is defined). # same thing happens

Hello, Has anyone out there encountered a problem like this: xyplot(Plasma ~ Serum | Analyte, data = sp.df, aspect = 1, layout = c(1, 1, 200), scales = list(relation = "free") ) Gives the error: Error in pretty(x[is.finite(x)], ...) : x must be numeric On the other hand, this works (but I don't want the default of having everything on the same

Hi, The following seems to be a bug introduced with version 1.8.0 (it worked without error on my installation of version 1.7.0): > test <- data.frame(time = I(c("2003-08-19:22:55:57"))) > test[["time"]] <- strptime(test[["time"]], format = "%Y-%m-%d:%H:%M:%S") Error in "[[<-.data.frame"(`*tmp*`, "time", value =

When I load an add-on package, is there any way to specify where it ends up in the search path (as with the pos argument to attach())? From the documentation for library(), this doesn't seem like an option. (I know I can detach packages and then reload them in the order I want; I'm looking for a less clumsy way.)

Hello, Could someone please tell me why the following doesn't work: I have a file C:\Program Files\R\rw1051\etc\Renviron.site, which contains the line: R_LIBS= "C:/Jim/LocalR-Libraries/FromCran"; "C:/Jim/LocalR-Libraries/Cantata" >From the documentation, I gather that I have put this file in the default location, but to be safe I also explicitly set the R_ENVIRON

Hi Listers, Surely, I just have a mental block and there is a more elegant way of creating a summary count (other than extracing it from ftable). I''d like to create a new data.frame containing counts of spell by loc ie have three columns showing spell,loc,count. Below the data.frame... Any help appreciated Thanks Herry spell loc 101 Parts 1 102 Overall 2 105 Parts 1 106

Hi there, I want to generate a large amount of functions, say f=function(x,t) exp(-t[1]-t[2]*g_1(x)-t[3]*g_2(1+x)) where g_1(x) and g_2(x) are from a long list of moments, such as x, x^2, log(x), log(1+x) .. and so on. Any suggestions on how to do this efficiently? thanks a lot. x.w

I am running into problems calling the library function nlme from within another function. Basically,the following function (with v a list containing data and initialization values) > testfunc function(dat=v) { test<-nlsList(result~a+(b-a)/(1+(conc/(c+z*cdiff))^d) |rep,start=dat$init,data=dat$mixeddat) return(nlme(test,random=b~1)) } produces the error message Error in eval(expr, envir,

Dear members, The documentation for source() says: Input is read and parsed from that file until the end of the file is reached, then the parsed expressions are evaluated sequentially in the chosen environment. What does this mean? I presume that any objects that are CREATED by the script are stored in the Global environment (if local = FALSE), but the rules for

Dear Duncun, thanks for the reply.... So when I run a script in the system command line by R CMD BATCH, the objects created in the script cannot be stored in the workspace ,right? If yes, how to save them? Moreover, the only way to save the objects CREATED from the script permanently is to save them to the disk, right? THanking you, yours sincerely, AKSHAY M KULKARNI

I've recently hunted down a troublesome bug in my own code, and am looking for an easy mechanism to detect this kind of error in other R code. The problem was an undefined variable inside of a function. Unfortunately, R looked for that variable in the global environment and found it since there was variable with that name in my testing scripts (note to self: do not name things "x").

R *does* search the environment stack. > search() [1] ".GlobalEnv" "package:stats" "package:graphics" [4] "package:grDevices" "package:utils" "package:datasets" [7] "package:methods" "Autoloads" "package:base What you seem to be missing is that a package may contain bindings that it

That is, the global environment does not contain x. Why doesn't it look further in the environment stack, like that of
