...=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 b$CharI<-as.character(b$CharI). Is there a less ugly way of doing this?

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.

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

...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*. https://cran.r-project.org/doc/manuals/r-release/R-lang.html On Tue, Jan 7, 2020 at 5:17 AM Steve Dutky <sdutky at gmail.com> wrote: > > 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.

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?

...is already installed. I ran afoul of steps in $(WINR)/<snip>/gnuwin32/MakePkg referencing symbols in the tools package in the system's version of R. Happily, these ran successfully against $(LINUXR)/R/bin/R. I hope some of this turns useful to others attempting this.
