How to set read.table variables to vectors?
The summary stats for the xin and yin variables below are correct. However, if I use plot(xin,yin), an exception is thrown saying that "object xin is not found." Also, it is apparent that I can't successfully replace the x and y vectors with values from xin and yin. The four plots on one panel are showing but the range of x and y is only [0,1], and therefore, it seems like an

Subsetting a data frame vs. subsetting the columns
Hi all, There seems to be rather a large speed disparity in subsetting when working with a whole data frame vs. working with just columns individually: df <- as.data.frame(replicate(10, runif(1e5))) ord <- order(df[[1]]) system.time(df[ord, ]) # user system elapsed # 0.043 0.007 0.059 system.time(lapply(df, function(x) x[ord])) # user system elapsed # 0.022 0.008 0.029

calling R's optimization routines from C
Hi, I have read R's Writing Extensions manual and am still confused about how to use some of the routines there when I call from C. Specifically, I am writing a little test function which I will optimize using the nmmin function which underlies R's optim() with Nelder-Mead. I guess I wonder what library/header files I should be using. I was using R_ext/Applic.h and linking with libR but I

[LLVMdev] LLVM ExecutionEngine/JIT trampoline question
I understand that we need to push the address to a register then branch using the register. But i am asking why there is a trampoline there such that a call to foo is first branched to an snippet and the snippet branches to the X86CompilationCallback. is this snippet necessary ?

Problem using model.frame with argument subset in own function

I want the method to return a data.frame that potentially only contains some of the variables in 'data', as specified by the formula. The problem I am having is in writing the function and wrapping it around model.frame. Consider the following data frame: dat <- data.frame(A = runif(10), B = runif(10), C
