...imagine that the Float2Int pass makes assumptions here, but haven't looked too carefully.) Point 2 is also important, because specifying saturation as the default behavior for float-to-int casts is becoming increasingly common. This would need two new intrinsics, such as: iYY llvm.fptoui.sat.fXX.iYY(fXX %a) iYY llvm.fptosi.sat.fXX.iYY(fXX %a) There is some precedent here with the recently introduced llvm.sadd.sat and llvm.uadd.sat intrinsics for saturating integer addition. The wasm backend also has custom llvm.wasm.trunc.saturate intrinsics for this purpose. These intrinsics would also...

...assed to the function. For compatibility reasons I cannot modify the parameter list of fx and I want to avoid setting variables in the global environment (e.g. via <<-) Is there a way, how to do this? Thomas P. The example: fx <- function(y) print(x*y) f <- function(fun, xx) { fxx <- function() {do.call(fun, list(y=3))} x <- x fxx() } f("fx", 13) ## does not work, because fx does not find x

Is there any reason to expect a problem ? i'm running this script on the cluster down the hall: module load R/2.11.0 R library(multicore) fxx<-function(ll) runif(1) mclapply(1:10,fxx) i get: Error in fork() : Unable to fork. less /proc/cpuinfo yields: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU X5365 @ 3.00GHz stepping : 11 cp...

...ivatives, and if on of these partial derivatives happens to be constant it fails. So e.g this works: library(Deriv) f <- function(x,y) (x-1.5)*(y-1)*(x-1.8)+(y-1.9)^2*(x-1.1)^3 fx <- Deriv(f,"x") fy <- Deriv(f,"y") fxy <- Deriv(Deriv(f,"y"),"x") fxx <- Deriv(Deriv(f,"x"),"x") fyy <- Deriv(Deriv(f,"y"),"y") fg <- outer(xg,yg,f) fxg <- outer(xg,yg,fx) fyg <- outer(xg,yg,fy) fxyg <- outer(xg,yg,fxy) fxxg <- outer(xg,yg,fxx) fyyg <- outer(xg,yg,fyy) And with f <- function(x,...

To use the modify the solution from Tony and I so that you can pass the name of the function, rather than the function itself, like this: x <- 7 fx <- function(y) print(x*y) f <- function(fun, x) { fun <- get(fun) environment(fun) <- environment() do.call("fun",list(3)) } f("fx",2) --- Date: Thu, 11 Mar 2004 08:22:45 +0100 From:

Hi, I posted this message earlier in "Rmetrics" and I don't know whether I posted in the wrong place, so I'm posting it again in Rhelp. I have a function in x and y and let's call it f(x,y). I need to get the Hessian matrix. i.e I need (d^2f/dx^2), (d^2f/dxdy), (d^2f/dydx), (d^2f/dy^2).I can get these using the D function. now I need to evaluste the hessian matrix for

...004 . . . The script is dynamically generated, periodically called, and should put the users (distinguished through their IP address) according to their traffic usages into lower priorities (axx,bxx,cxx) respecting different bandwidth needs but also respecting minimum rates for different groups (fxx). Now the borrowing among user classes (1:3xxx) is working; but for some reason and I just can''t figure out why, the group classes (fxx) don''t borrow from each other when their is unused bandwidth available. The "ceil 10mbit" just seems to be ignored :( e.g.: class ht...

Can someone verify whether or not this is a bug. When I substitute all occurrence of "\\B" with "X" R seems to correctly place an X at all non-word boundaries (whether or not I specify perl) but "\\b" does not seem to act on all complement positions: > gsub("\\b", "X", "abc def") # nothing done [1] "abc def" >
