The new package obsSens is now on the CRAN mirrors. This package has tools for doing senstitivity analysis for observational studies. The common criticism of observational studies is that there is the possibility of an unmeasured variable that is related to both the response and the predictor of interst that could explain the observed relationship.

...l LLVM tools. * LLVM now supports unordered floating point comparisons. Optimization improvements: * The induction variable analysis routines are much more aggressive. * The -indvars pass implements linear function test replacement and exit value substitution. * LLVM includes a context-senstitive alias analysis for global vars. * LLVM includes an implementation of Andersen's alias analysis. * LLVM includes new loop unrolling and loop unswitching passes. * LLVM includes a simple dead store elimination pass. Code generator improvements: * The native code generators now default to...
