I have a function that manipulates a list of numeric and character components of equal length and wants to return a data.frame. EG, f<-function() { a<-list(Int1=1:5,Char1=letters[1:5],Char2=letters[6:10]) b<-data.frame(a) } How can I get the columns Char1, Char2, (...CharN) returned coerced to character and not factor? It appears that I could coerce individual columns by

Hi, R Lovers! I have some survey data. I'd like to run R or R packages for processing data inputted from AHP(Analytic Hierarchy Process) survey. Are there any R packages or subsititues for running data from AHP survey.

If changes to sprintf behavior are being considered, would it be possible to allow some of the other K&R conversion specifiers? xX - for integer to hex conversion, and c - for ascii value to character conversion would all be useful for me.

As an inveterate user of vi, I was pleased to stumble on how to use it for editing R commands. When an interactive R session is launched under unix, the command line editor most likely defaults to emacs. Typing <esc>,<ctrl>+j will switch this to vi editing mode (see below for possible exceptions). excerpted from readline(3) manpage: vi-editing-mode (M-C-j) When in emacs

I need to write some documentation: I'm looking for a standard, consistent way of referring to the components and attributes of R data structures. Googling and Stackoverflow yield a variety of github sites that do not seem to be particularly authoritative. I was hoping to find a BNF/ABNF grammar for R. I've looked at the output of bison -v ./R-3.6.2/src/main/gram.y but it does not

Dear all, I expect that I am on thin ice trying to build this on freeBSD 4.10, however, after tweaking Makefile-rcb v11Oct04 /* MAKE=gmake; MINGW_CROSS = mingw-cross4 */, I encounter: mingw32-gcc -isystem ~/RCrossBuild/cross- tools/mingw32/include -O2 -Wall -pedantic -I../include -I. - DHAVE_CONFIG_H -DR_DLL_BUILD -c dynload.c -o dynload.o dynload.c: In function `R_loadLibrary':

@steve Seek for online document named "writing R extensions" chapter 2. It tells how to describe a list structure using item markup for R documentation files, if indeed this matches your search, thing I am not sure. Something that looks like... value{ The \\code{list} owns following names \\item{alpha}{double vector} \\item{beta}{integer vector} \\item{delta}{raw vector} } Best Le

Do you just need something on pen and paper? (In which case, I don't see why it needs to be "standard"). Or do you need something that can be used with bison/yacc/cup/etc to produce a parser? On a side note, I would say that the R Language Definition is the "standard" way. But I do recognize that this has a different flavour to modern language implementation *theory*.

Currently the function symbols() permits plotting of circles, squares, rectangles, stars, thermometers, and boxplots. Can anybody suggest an approach for extending/cloning this function to handle arbitrary shapes specified, perhaps, as bitmaps, or as postscript primitives?

Dear All: I encountered and apparently overcame problems following Yan and Rossini?s procedure for "Building Microsoft Windows Versions of R and R packages under Intel Linux" (http://cran.r-project.org/doc/contrib/cross-build.pdf): I have successfully cross-compiled R packages for Windows on a FreeBSD 4.10 i386 system. My revisions to Makefile-rcb (http://cran.r-
