Question on graphs: The default case for drawing a graph in R, is where a little space is left on the x and y axis before the first tick i.e. even if I say xlim=c(0,1) -- there will be some space between the edge of the x-axis and where 0 is placed. If I want 0 on the edge, how do I do it in R? Area under the curve: I have a 45 degree line and a curve above or below it. Is there a way in R

I have two dataframes C and C1. Each has three columns viz. state, psu and weight. The dataframes are of unequal size i.e. C1 could be 2/25/50 rows and C has 42000 rows. C1 is the master table i.e. C1$state, C1$psu and C1$weight are never the same. ThisA. P., Urban, 0 is not so for C. For example C state, psu,weight A.

I am trying to do a forecasting exercise for a series, x. My forecast model consists of the following I first regress log(x) on time and dummy variables for each month. lm(log(x) ~ time + monthly dummies) I then use predict() to obtain a prediction for the next year. I then fit an AR(6)/AR(12) model on the residuals of the regression. I use predict() here also to obtain the prediction for the

I don't know how to do that. Rather new to LLVM. The functions that get stripped out are native C++ functions that I'm registering in my execution engine by doing: // Create a function type object for the function llvm::FunctionType* pFuncType = llvm::FunctionType::get(returnType, argTypes, false); // Create a function object with external linkage and the specified

Yes, and this is what I'd suggest since it's quite a bit faster. Basically you'd use a function pass manager there are some passes which are function only and then get pointer to function as normal. -eric

In the TargetData class (available from you ExecutionEngine), you have some informations available (such as StructLayout...).

There's no right way to determine this. It depends on what you need/ want from your

I was simply surprised because some C++ code I implemented/translated into LLVM IR ran significantly slower in the JIT than the C++ version. The code in question was mean to implement the "plus" operator in my scripting language, and had different behaviors depending on the type of the objects being added. I expected it to run faster as I was eliminating a call to a C++ function by

I went ahead and implemented the allocation based on the maximum size of all structs seen so far... The problem is, the TargetData object from ExecutionEngine gives me a size of 12 for a struct containing a pointer and an i64 (on a 32-bit machine). However, the generated code seems to assume an alignment of 8, and tries to read the i64 value at offset 8, which obviously reads an invalid value.

The linkage type is set to external, I have little code snippet I use to register those native functions in the first post of this topic. The global DCE pass deletes the unused native functions when run. I commented it out for now...

That sounds rather cumbersome, is there no simpler way to get the actual size of a struct?

Is there a webpage documenting these function passes? Which ones should I run to maximize performance? Also, do the machine function passes automatically run (I'm assuming those optimize the final x86 code).
