In very special cases packages may create binary files other than theshared objects/DLLs in the src directory. Such files will not beinstalled in a multi-architecture setting since R CMD INSTALL--libs-only is used to merge multiple sub-architectures and it onlycopies shared objects/DLLs. If a package wants to install otherbinaries (for example executable programs), it should provide an Rscript src/install.libs.R which will be run as part of theinstallation in the src build directory instead of copyingthe shared objects/DLLs. The script is run in a separate Renvironment containing the following variables: R_PACKAGE_NAME(the name of the package), R_PACKAGE_SOURCE (the path to thesource directory of the package), R_PACKAGE_DIR (the path of thetarget installation directory of the package), R_ARCH (thearch-dependent part of the path, often empty), SHLIB_EXT (theextension of shared objects) and WINDOWS (TRUE on Windows,FALSE elsewhere). Something close to the default behavior couldbe replicated with the following src/install.libs.R file:

In order to use this dynamic approach (e.g., dll$myRoutine), oneneeds the reference to the DLL as an R variable in the package. TheDLL can be assigned to a variable by using the variable =dllName format used above for mapping symbols to R variables. Forexample, if we wanted to assign the DLL reference for the DLLfoo in the example above to the variable myDLL, we woulduse the following directive in the NAMESPACE file:


If you need to look in more detail at the timings for examples, useoption --timings to R CMD check (this is set by--as-cran). This adds a summary to the check output for allthe examples with CPU or elapsed time of more than 5 seconds. Itproduces a file mypkg.Rcheck/mypkg-Ex.timingscontaining timings for each help file: it is a tab-delimited file whichcan be read into R for further analysis.


Timings for the tests and vignette runs are given at the bottom of thecorresponding log file: note that log files for successful vignette runsare only retained if environment variable_R_CHECK_ALWAYS_LOG_VIGNETTE_OUTPUT_ is set to a true value.


The START command retrieves a script and runs the commands it contains. Use START to run a script containing SQL commands, PL/SQL blocks, and SQL*Plus commands. You can have many commands in the file. Follow the START command with the name of the file:


The UrlResource wraps a java.net.URL, and may be used to access any object that isnormally accessible via a URL, such as files, an HTTP target, an FTP target, etc. AllURLs have a standardized String representation, such that appropriate standardizedprefixes are used to indicate one URL type from another. This includes file: foraccessing filesystem paths, http: for accessing resources via the HTTP protocol,ftp: for accessing resources via FTP, etc.


In practice, if true absolute filesystem paths are needed, it is better to forgo the useof absolute paths with FileSystemResource / FileSystemXmlApplicationContext, andjust force the use of a UrlResource, by using the file: URL prefix. 041b061a72
