Plotting a curve for a Holling Type III Functional Response
Hey, So I have a scatter plot and I am trying to plot a curve to fit the data based on a Holling Type III functional response. My function is this: nll2<-function(a,b) { conefun<-(a*DBH^2)/(b^2+DBH^2) nlls2<-dnbinom(x=cones ,size=DBH, mu=conefun,log=TRUE) -sum(nlls) } and my plot is this: plot (DBH,cones) DBH is on the x-axis and cones is on the y-axis. How do I get the curve

[LLVMdev] problem trying to write an LLVM register-allocation pass
Hi Susan, In x86-64 the REX prefix must be used to access an extended register (r8-r15 and their aliases), but cannot be used when accessing the high byte of the ABCD regs (AH, BH, CH, DH). In your test case you have hardcoded %vreg1 to R8B, and %vreg15 to AH, and the test case contains a copy between these registers. The copy simultaneously must have a REX prefix, and cannot have a REX prefix,

Windows testing
R 1.4.0 is now sinking into feature freeze, and we'd like some help testing it under Windows. Duncan Murdoch and Uwe Ligges have already volunteered. I've put a copy of SetupR140.exe at http://www.stats.ox.ac.uk/pub/bdr/RWin Also in that directory is a file TESTING suggesting some tests, not all of which have been run on this build. As the graphics internals have been changed a lot
