Hi, When loading a package that provides the user-supplied RNG hook user_unif_rand, calling getNativeSymbolInfo("user_unif_rand") returns informations about the loaded symbol. I am using this to identify which package currently provides the RNG hook. The results are the same on windows and linux if only one library provides the hook. If one loads a second package that provides this hook, then on...

I use recordPlot() to save plots to disk that I render later to a variety of formats. This works fine for base R plots and ggplot2 plots, and also used to work for lattice plots. However somewhere in version 2.14 things stopped working for lattice plots. Here is an example: library(lattice); histogram(rnorm(100)); x <- recordPlot(); saveRDS(x, "myplot.rds"); y <-

Help for is.loaded() and getNativeSymbolInfo() say not to use symbol.For() to convert to Fortran-specific symbols. However, on Linux, getNativeSymbolInfo is unable to find 'initaquaphy' in 'test.so', but does find 'initaquaphy_'. Note that is.loaded() works as advertised. Furthermore, this code works in Windows, R-2...

Dear all, I’m not sure if it is O.K. to ask this question here. But where can I find the code for the function ‘C_Cdqrls’ which is called by the R function ‘lsfit‘. Thank you all. Sorry for being naïve if so. -------------------- Ziqiang Zhao 2013-04-23 [[alternative HTML version deleted]]

...tric distributions for all 2 by 2 tables. This might be slightly slower for a few cases, but works much better for tables with some large counts. There is a new option to simulate the p-value for larger than 2 x 2 tables. o for() now supports raw vectors as the set of indices. o getNativeSymbolInfo() is vectorized for the 'name' argument. It returns a named list of NativeSymbolInfo objects, but is backward compatible by default when called with a character vector of length 1, returning the NativeSymbolInfo object. o help.search() no longer attempts to handle packages installe...
