I have a vector of values -1, 0, 1, say a <- c(0, 1, 0, 1, 1, -1, -1, -1, 0, -1, -1) I want to create a vector of the cumulative sum of this, but I need to set a maximum and minimum value for the cumsum, for example: max_value <- 2 min_value <- -2 the expected result would be (0, 1, 1, 2, 2, 1, 0, -1, -1, -2, -2) The only way I managed to do It, was res <-

Hello! I have a problem with my Genius tablet. It works on GIMP (native) but not on Photoshop, I tried CS and CS2. I got how to make a log file from another thread, but it was old and photoshop version was different. Tablet is a Genius G-Pen 4500. Name UC-LOGIC Tablet WP5540U. Distro is Arch Linux, Wine package version is 1.3.36-1. Thanks a lot :). Here is the log: Code:

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 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, 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, 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, Is it possible to extend the R lexer/parser to include multiline comments like /* acomment */ ? This way I can integrate emacs org-mode with my R code, so that I can have a table of contents, section folding, html-output of source etc. e.g /* * Display Code */ #+BEGIN_SRC R foo <- function(...){ stuff } #+end_src and so on . Thanks 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

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 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, I have to write single Long to a server written in java. The server passes the input as in.readLong() // it expects to receive 8 bytes In Python, i can do it by sending struct.pack( "!q", value) However, I have tried this writeBin(length(x),con=conn,endian="big") #conn opened in binary But the response on the server side is wrong, eg. 1 is received as

=== PROBLEM === (See this bug https://llvm.org/bugs/show_bug.cgi?id=26445) IR contains code for loading a float from float * and storing it to a float * address. After canonicalization of load in InstCombine [1], new bitcasts are added to the IR (see bottom of the email for code samples). This prevents select speculation in SROA to work. Also after SROA we have bitcasts from int32 to float.

sscanf is sadly not safe (because it doesn't handle integer overflow correctly), and strto*l functions are a pain to use correctly. Therefore add some functions to hide the pain of parsing integers from the command line. The simpler uses of sscanf and strto*l are replaced. There are still a few where we are using advanced features of sscanf. --- docs/nbdkit-plugin.pod | 48

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 call a function via .Call passing to it a raw vector(D) and an integer(I) The vector is a series K1,KData1, V1,VData1, K2, KData2, ... where the integer K1 is the length of Data1 and similarly for Ki (wrt Datai)(similarly for V*) There 2*I such pairs( (Ki,KDatai), (Vi,VDatai)) The numbers Ki(and Vi) are written in network order. I am returning a list of I elements each element a

Hello, I was looking at the R (installed on RHEL6) shell script and saw R_HOME_DIR=/usr/lib64/R. Nowhere (and I could have got it wrong) does it read in the environment value R_HOME_DIR. I have the need to rsync the entire folder below /usr/lib64/R to another computer into another directory location. Without changing the R shell script, how can i force it read in R_HOME_DIR? Or maybe i
