My C function is void main(char *str) { Rprintf("%s",str); } Can you help how to achieve this using .C interface? Thanks Jaimin [[alternative HTML version deleted]]

Apologies for asking something that is probably very obvious, i just started with S4 classes and i guess i am not finding documentation that lays out the grammar rules and gives enough examples. I understand that main method of writing a member function is to write a generic function and setMethod for this particular class. This, however, presumes that there is "virtuality" for this

Hi, The following function works, but is there a neater way to write it? f = function(x,...) { # return a character vector of the arguments passed in after 'x' gsub(" ","",unlist(strsplit(deparse(substitute(list(...))),"[(,)]")))[-1] } > f(x,a,b,c*d) [1] "a" "b" "c*d" > Thanks. [[alternative HTML

Is there a tidy way to get the names of objects passed to a function via the "..." argument? rbind/cbind does what I want: test.func1 <- function(...) { nms <- rownames(rbind(..., deparse.level=1)) print(nms) } x <- "some stuff" second <- "more stuff" test.func1(first=x, second) [1] "first" "second" The usual

I would like to make a new vector with values taken from two existing vectors conditional upon a third. At present I am doing this with a for loop but wonder if there is not a neater way, given some of the very neat things R can do. a<-rep(c("A","B"),50) b<-rep(1,100) c<-rep(2,100) a is thus "A" "B" "A" "B" "A"

Hi Everyone, I have csv file which is in following format xmin,xmax,ymin,ymax,zmin,zmax I want to plot 3d graph with all the all octants being displayed as well. Any idea? I have used scatterplot3d package but it does not seem to have anything by which i can draw "octants" inside cube as well. Thanks [[alternative HTML version deleted]]

Hi Everyone, I am new to R and I am trying to return array(dynamic) from C to R. But when I print array(vector) in R it gives NA as output. When I print array in C it gives correct o/p but some how it is not returned to R. *Code in C:* void test(double *vec,double *size){ vec = (double *)calloc(2 , sizeof(double)); *(vec+0) = 1; *(vec+1) = 2; *size = 2; } *Code in R:*

I'm looking to connect a BMC 450 to an asterisk with a Digium Quad E1 card. Am I right in thinking that I'll need a special 'crossover-E1' RJ45 cable? If so, any clues where I might buy one in the UK? The Digium card sellers don't seem to stock such a thing. Thanks. Tim. Tim Panton - Web/VoIP consultant and implementor www.westhawk.co.uk

I work in the UK and therefore most of my currency figures will be in UK pounds. I realise that to format a number to a currency format I can use: number_to_currency(amt, :unit => "?") but it would be more convenient to set ? as the default currency symbol. What is the best way to do that? Should I edit line 39 of this file:

If I run an analysis which generates statistical tests on many SNPs I would naturally want to get more details on the most significant SNPs. Directly from within R one can get the information by loading RSNPer (from Bioconductor) and simply issuing a command SNPinfo(2073285). Unfortunately, the command cannot handle a vector and therefore only wants to do one at a time. I tried the lapply and

Hi guys, hoping someone can give me a pointer with this? I have a Javascript variable that I''m updating dynamically as a user interacts with the page. I want the user to be able to save it''s value at any time along with some text data in a pop-up form, so the best way I can think of is to pass it through the params hash without writing it into the form. I''m not totally

Hi, I would like to make a suggestion for a small syntactic modification of FUN argument in the family of functions [lsv]apply(). The idea is to allow one-liner expressions without typing "function(item) {...}" to surround them. The argument to the anonymous function is simply referred as ".". Let take an example. With this new feature, the following call

I have an app with the following models: course belongs_to :semester semester has_many: courses belongs_to :education education has_many :semesters In my old app (rails 1.2.6) I was able to access variables via controller @courses = Course.find(:all) view file: <% for course in @courses %> <%= course.name %> <- this line works <%= course.semester.name %> <- this is now

I'd agree with you John. I'm trying to get away from Amanda's unpredictability and go back to using scripts to drive dump (for ext2/3/4) and xfsdump (for xfs). Is there any easy way to tell rear to include xfsdump and dump capability? If the commands are there then its trivial to restore data. What I've done in the past is before the nightly backup write a small file to the
