I am investigating some approaches to reproducible research. I need in the end to produce .html or .doc or .docx. I have used hwriter in the past but have had some problems with verbatim output from R. Tables are also not particularly convenient. I am interested in R2HTML and R2wd in particular, and possibly odfWeave. Does anyone have sample documents using any of these approaches which

Aloha all, I love using ggplot. It took a while to get used to the grammar of graphics, but it is starting to get easy now that I am thinking in a more structured way. A question. I'm making a wind rose that I'd like to be oriented with due north straight up. I've discovered that the orientation is sensitive to how north is represented. When north is represented as 0,

I need an analogue of "uniq -c" for a data frame. xtabs(), although dog slow, would have footed the bill nicely: --8<---------------cut here---------------start------------->8--- > x <- data.frame(a=1:32,b=1:32,c=1:32,d=1:32,e=1:32) > system.time(subset(as.data.frame(xtabs( ~. , x )), Freq != 0 )) user system elapsed 12.788 4.288 17.224 --8<---------------cut

Hello Everyone,   Been learning R over the past several months. Read several books and have learned a great deal about data manipulation, statistical analysis, and graphics.   Now I want to learn how to make nice looking documents and about "literate programming." My understanding is that R users normally do this using LaTeX, MiKTeX, LyX, etc. in conjuction with Sweave. An alternative

Hi, I am wondering if there is a way to call Gnuplot from R and/or if anyone can recommend a package on CRAN capable of doing this? Thanks, Chris PS - Please cc me on the response. [[alternative HTML version deleted]]

Hi all, I am taking this over from r-help (see http://permalink.gmane.org/gmane.comp.lang.r.general/273985). I experience a segfault when calling gplots::heatmap.2(), but only when certain other packages are loaded. I am not sure for the correct place to send this bug report. Should I send it to the package maintainers directly? If R-help is the wrong place, please feel free to direct me to

Hello, Is there a way to add ylab on the right hand side also (in lattice)? Different from the left hand side? Cheers Saptarshi [[alternative HTML version deleted]]

Hello, I have a multi-page display each consisting of two-panels above each other. I need to draw a line from the top panel to bottom panel. Using current.vpTree() i find that "plot1.panel.1.2.vp" and "plot1.panel.1.1.vp" are the top and bottom ones respectively. I am using the following code(inspired by Paul Murrell's R Graphics) to draw a line. (All the

Hello, I wrote a package, which in the NAMESPACE file exports functions like this: exportPattern("^\\rh") On R-2.8 (Linux, 64), upon loading the package I have the rh functions present. On R-2.10, Mac OS X, (32 bit), it builds, loads, but the functions are not loaded, i.e the only function is rhyper (which is not from my package). Is there something wrong with my package setup?

Hello, I was trying this bit of code (i know it is an extreme case) g=function(r){ if(r==1) return(list(x=1)) else return(list(x=g(r-1))) } For z=g(500), the code runs but when I print z i.e >> z I get <environment: R_GlobalEnv> *** caught bus error *** address 0x1, cause 'non-existent physical address' Possible actions: 1: abort (with core dump, if enabled)

Hello, Suppose I have an expression, E, which accesses some variables present in an environment V. I do this via eval(E,envir=V) however all assignments end up in V. I would like the results of assignments in E to end up in the .GlobalEnv ? Or at least the calling environment. Is there a quick way to this instead of iterating over all objects E and assigning into .GlobalEnv? Thank you Saptarshi

Hello, Suppose in the following code, PROTECT(sr = R_tryEval( .... )) sr is a RAWSXP vector. I wish to return another RAWSXP starting at position 13 onwards (base=0). I could create another RAWSXP of the correct length and then memcpy the required bytes and length to this new one. However is there a more efficient method? Regards Saptarshi Guha

Hi, I am currently trying to find a replacement for a dinosaur PBX and want to replace it with a VoIP solution. We have just moved our lines over to an Optus Multiline from a Telstra ISDN Onramp 30 service with 100 lines. My question for you good people is what sort of hardware do I need to interface Asterix into the Optus Multiline? The Optus service is terminated in my office to a SHDSL

Hello, I have some code which generates lattice objects. The function recieves serialized forms of the lattice objects which it then unserializes and then adds to an ArrayList<REXP>. REXPRaw rser = new REXPRaw( target ); //target contains the raw serialized forms of lattice objects rconn.assign("temp",rser); REXP ret =

Hello, I'm not sure how to go about this. Suppose I have a function SEXP boo(SEXP x){ //do something } Also, I have an executable which embeds R in itself. I would like to provide a R function to user code to call that calls 'boo' e.g ##user supplied expression that is given to me x<-1 boo(x) One way is to create a library with function boo that performs .Call to boo, but is

Hello, My plots consist of 2 rows, 1 column, many pages I've managed to selectively turn of strips for the bottom panel and roll my own strip for the top par.strip.text = list(lines = c(0,3),cex=0.6) I have my own custom prepanel function too. What i'd like to do is turn off the x-axis for the top panel (since on a given page the xlim is same for both top and bottom panel, but the

Hello, This is a question that probably reveals my lack of understanding. In a C function (call it cfunc), i created a SEXP, called S, and then called R_PreserveObject on S. I returned the SEXP to the calling R function (call it rfunc). Note, I didn't call R_ReleaseObject on S. v <- .Call("cfunc") So, are the following statements correct 1. S is 'doubly' protected

Hello, I have question about the overhead in lapply. x is a list of 3000 lists. Each of the i (1<=i<=3000) list elements is pair of two elements: a string vector and a data frame x is roughly 235MB. > gc() ## > z <- system.time(y <- lapply(x,function(r){ system.time(serialize(r,NULL))['elapsed'] })) > sum(unlist(y)) 18.812 > z user system elapsed 494.144
