Can anybody explain why > ?function + + + ) Error: syntax error so that > ?"function" is necessarty??? This seems reasonable with ?"?", but I can not see why the "" are necessary with function (and some other examples) Kjetil Halvorsen -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

This is a follow-up to bug sent to days ago, which bounced from r-devel because the example was to large. Now example is smaller, and behaviour is as belo, EXEPT that r-windows not any more bombs, so main problem is "xpdrows.data.frame"??? By the way, how to debug this example under windows? debug() doesnt accept the functions used (.Primitive), and R wont run under gdb --- may have

Full_Name: Roger Bivand Version: 0.99.0 OS: RH Linux 6.1 Submission from: (NULL) (158.37.60.152) I am working on an interface between R and the GRASS geographical information system, written in R, with no dynamically loaded code. I have written full examples, and tested then under R 0.90.1, both by entering example() for each function and R CMD check, both of which worked without problem. Under

Hola! I ask here since I learnt from this list that the LaTeX package listings should be good for typesetting R code. I encountered one problem: \begin{lstlisting} X %*% V \end{lstlisting} in the output the * in %*% disappears! same with %/%, etc, the / disappears. Any ideas? Kjetil -- Kjetil Halvorsen.

I am trying to source a file defining a dataset, giving the full path.

I just discovered that when the VGAM package (not on CRAN) is loaded, glm() doesn't work. This is because VGAM defines a family function() which gets found by glm() in place of the family function from stats. Then VGAM:::family returns an object which doesn't have a $family component, (it has a component $vfamily). I thought namespaces should protect us from this happening? Kjetil --

With rw2010dev I get a strange protect(): protection stack overflow error with a small data frame which otherwise is usable: If anybody wants to have a look I can provide an RData file with the problematic data frame. Doesn't seem to be necessary, the following simulated example generates the error: > testmat <- matrix(1:80, 20,4) > dim(testmat) [1] 20 4 > str(testmat) int

I found the need of converting a matrix into a list of its columns (for use with do.call), and was surprised there was no method as.list.matrix, it could easily be a part of as.list default I wrote my.as.list.matrix <- function(mat) { if(!is.matrix(mat))stop("Argument must be a matrix") n <- NCOL(mat) res <- vector(mode="list", length=n)

Hola! I have the following in a .Rd file: \eqn{\mbox{coef} = c(\mbox{coef}[1],\ldots, \mbox{coef}[n]) } {coef = c(coef[1], coef[2], \dots, coef[n])} However, both arguments come out in the latex file! Whats happening? Kjetil Halvorsen

I encountered something strange with read.spss (package foreign, version 0.7 with R2.0.0 and version 0.8 with R2.0.1 beta, windows XP) I made a test file test.sav with SPSS version 11.5.1 containing only one numeric variable, with a value label for one value not occuring in the file. According to ?read.spss this should result in a factor, but it results in all NA. Using the argument

Hola! The R FAQ says: 7.12 How do I convert factors to numeric? It may happen that when reading numeric data into R (usually, when reading in a file), they come in as factors. If f is such a factor object, you can use as.numeric(as.character(f)) to get the numbers back. More efficient, but harder to remember, is as.numeric(levels(f))[as.integer(f)] In any case, do not call as.numeric()

Hola! Starting with rw1071, just after starting Rgui the scope is not with Rconsole, but some other place. This means I have to do a mouse click in the Rconsole before starting to write the first command. Since I always forget this, I end up writing the first command twice. This is of course only a minor nuisance, but why is focus no longer set to Rconsole window when start-up? This is on
