Hi, I am a rails and ruby nuby :-) How do you pass data between different controllers and views? I have a page ( a quote) that I am editing url ....quote/edit/6 6 id the current id.

Good Friday Everyone :-). These are my models: Problem -> has_and_belongs_to_many :tags Tag -> has_and_belongs_to_many :problems Now if a tag does not exist and I create it and associate it to the problem it works self.tags << Tag.create(:name => tag) But if I have the tag already in the DB and just want to link it to another problem it does not really like me. I do it

I have a batch job that will call script/runner, I would like in this call to create html formated email and save it to the database. This is easy enough in a controller with yournewhost.email = render_to_string :action => "email_newhost_ready", :layout => false But render_to_string is only available in controller action pack, is there a easy way to render_to_string in a Model? Or

I've been trying to install R into a user's home directory for them by compiling from source code, on a machine for which neither of us has administrative access. I've run configure using the --prefix option to specify their home directory. This seems to work OK up to a point, but when running make, it seems to expect to be able to install IDL into /usr/local/, and if you are unable

Hi, I have a problem sorting and selecting entries within a data-frame and I don't know if it is possible to solve it with R ... (probably yes, but I have no idea how).

All, I have some data on parasites on apple leaves and want to do a goodness of fit test to a Poisson distribution. This seems to do it: mites <- c(rep(0,70), rep(1,38), rep(2,17), rep(3,10), rep(4,9), rep(5,3), rep(6,2), rep(7,1)) tab <- table(mites) NSU <- length(mites) N <-

Hi all (really probably just Deepayan): In the plot below I want to add text on either side of each violin plot that indicates the number of observations that are either positive or negative. I'm trying to do this with ltext() and I've also monkeyed about with panel.text(). The code below is generally what I want but my calls to ltext() are wrong and I'm not sure how to fix them.

Dear all, ## I have 4 tables like this: satu <- array(c(5,15,20,68,29,54,84,119), dim=c(2,4), dimnames=list(c("Negative", "Positive"), c("Black", "Brown", "Red", "Blond"))) dua <- array(c(50,105,30,8,29,25,84,9), dim=c(2,4), dimnames=list(c("Negative", "Positive"),

How can I generate LLVM IR for both logical NEG (!)? For example, if I have Int32Ty a, For the bitwise NEG(~): c = ~a ; I can use the following API from LLVM: BinaryOperator *neg = BinaryOperator::CreateNeg(nbits, "bitwiseNEG", insertBefore); How, if I want to generate logical NEG: c = !a; what should I do for this?

Dear useRs, I got stuck trying to generate a palette of topographic colors that would satisfy these two requirements: - the pallete must be 'anchored' at 0 (just like on a map), with light blue/lawn green corresponding to data values close to 0 (dark blue to light blue for negative values, green-yellow-brown for positive values) - the brown must get darker for higher positive

Dear community I am using ggraph to plot a network analysis. See part 2 in the working example. Besides different colors for different groups of nodes: --> geom_node_point(aes(size = V(network)$hub_score*200, color= as.factor(V(network)$community))) I additionally want to consider different colors for different edge groups The grouping is defined in the edge_list$relationship: negative

Thanks, Bruce. So, what is the easiest way to check if there is any bit set to 1 in a <N x i1> vector type? I used bitcast instruction to cast it into "iN" first and them compare iN to 0. Do you have a better way to do it? Thanks again. On Fri, Apr 10, 2015 at 5:22 PM, Bruce Hoult <bruce at hoult.org> wrote: > LLVM doesn't have a "logical neg" (or
