I'm using an S4 object with a slot of type 'call': I would like to be able to initialize it with something like NULL or NA (indicating that there is no information in the slot) but the value should comply with the fact that it must be of type call. Is there any simple way to obtain this? Thanks for any hint, Roberto -- <r/> | Roberto Brunelli - [scientist at Fondazione

Is it possible to write a support function to automatize selective argument expansion (based on argument value type) as in the following example, in order to write terse code even when there are many arguments? Forcing evaluation of all arguments is not a problem ... ______________________________________________Thanks a lot!__________R_ # When called with document = 1, we have the

I'm trying to write a simple wrapper for plotting functions to make them print to postscript, something like ploteps <- function(file, plotFunction, ...) { args <- list(bquote(...)) # prepare postscript device do.call(plot, args) # close postscript device } I have inserted the bquote otherwise I get a lot of numbers in the plot when I plot/hist something. But if I invoke

How can I apply function f, that I get as an argument as in func <- function(f, ...) { . . . } to a list of arguments list(a, b, c) (eg the ... argument of func above) in order to obtain f(a, b, c) Thanks a lot, Roberto [[alternative HTML version deleted]]

Hi! I'm trying to use "Marco Polo Gro?er Reiseplaner 2005/2006" with Wine 0.9.13 on Gentoo Linux. To use it, I ran travel\setup.exe from the DVD and the setup just stops, before the "real thing" starts. Please see http://www.myimg.de/?img=BildschirmfotoWinedesktopSeaa8.png In the terminal window from which I started wine, I get: alexander@blatt ~ $ wine

When I run R CMD Rd2pdf on the man pages of a package, ie R CMD Rd2pdf man I get Converting Rd files to LaTeX Warning in parse_Rd("man/mpra-package.Rd", encoding = "unknown", fragment = FALSE, : man/mpra-package.Rd:6: unknown macro '\packageTitle' Warning in parse_Rd("man/mpra-package.Rd", encoding = "unknown", fragment = FALSE, :

Bug or feature? I get the following error from parse_Rd() when a user Rd macro (including system ones) is invoked with empty argument {}, eg \mymacro{}: Error in tools::parse_Rd(fn) : Value of SET_STRING_ELT() must be a 'CHARSXP' not a 'NULL' A full example is further below with the system macro \CRANpkg{}. In this example it doesn't make sense to use empty argument but

Hi, I'm using R to find esplicit functions fitting set of data. The data contains about 30 points, which have different weights (number of cases represented from the point). I plot the points, choose "by eye" a function made with exp or arctg or polinomial and use nlm to minimaze the root mean error with correct the weights. For Example: Err <- function(p) sum((weight*(y

I have a list with four fields and 3500 records, from a MySQL table.

While on the topic of Rd macro arguments, it seems that if a multiline argument is supplied, the lines after the first are silently ignored: f <- tempfile() mac6 <- "\\newcommand{\\mac6}{mac6: #1}" cat(mac6, "\\mac6{2*3 2+2 sin(pi) }\n", file = f) rd <- tools::parse_Rd(f) > rd mac6: 2*3 --- Georgi Boshnakov -----Original Message----- From: Tomas Kalibera

I was writing Rd documentation for a new package when I came across this issue. Here's the smallest example: > library(tools) > cat("\\examples{x <- '<%=rnorm(1)%>'}\n",file=file.path(tempdir(),'test.Rd')) > readLines(file.path(tempdir(),'test.Rd')) [1] "\\examples{x <- '<%=rnorm(1)%>'}" >

Hi (Duncan?), The other day I noticed some characters will cause errors in R CMD CHECK because of parse_Rd(), and AFAIK, these chars include '%', '{' and '}'. For example, note the comments in the example section: %~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~% \name{testfun} \Rdversion{1.1} \alias{testfun} \title{ A Test } \description{ A test } \usage{ testfun() } \value{ NULL }

No, I do not get the same as you. I have tested with R-devel and R-patched compiled today. When I do R CMD Rd2pdf mpra I get (as reported a few days ago) Hmm ... looks like a package Converting Rd files to LaTeX Error : mpra/man/mpra-package.Rd:6: file './DESCRIPTION' does not exist whereas you (Kurt) reports that this works on zTree. When I do R CMD Rd2pdf mpra/man I get - a

Hi everyone, >From the currently available version of the package VBmix, I would like to retrieve the intermediate .tex file that generates the VBmix-manual.pdf file. Formerly, running R CMD check with --no-clean allowed to get this tex source from a hidden directory : this feature was removed, but can apparently still be accessed through R CMD Rd2pdf --no-clean. Surprisingly, while the
