Multicore-enabled SAGA GIS modules such as the one used by rsaga.pisr seem to run in multicore mode by default when this argument is not specified, therefore cores should only be specified to use a smaller number of cores than available on a machine.rsaga.env.)FALSE.intern=TRUE, reduce the text output of SAGA returned to R by eliminating redundant lines showing the progress of module execution etc. (default: TRUE).TRUE): call rsaga.module.exists to determine if the specified module can be called in the current SAGA installationTRUE): for internal purposes - can be used to suppress warning messages generated by failed SAGA_CMD calls; currently used by rsaga.get.lib.modules and related functions; see options argument warn for details" "; currently for internal use): defines the character symbol used as a separator between each argument name and argument value passed to saga_cmd. SAGA GIS 2.1.0 (RC1) seems to move toward "=" as a separator, but " " still works and some modules (e.g. the used by rsaga.pisr) don't seem to work with argsep="=". Future releases of RSAGA may change the default argsep value and/or delete or ignore this argument and/or move it to rsaga.env.system.intern argument passed to system.If intern=FALSE, a numerical error/success code is returned, where a value of 0 corresponds to success and a non-zero value indicates an error. Note however that the function always returns a success value of 0 if wait=FALSE, i.e. if it does not wait for SAGA to finish.If intern=TRUE (default), the console output of SAGA is returned as a character vector. This character vector lists the input file names and modules arguments, and gives a more or less detailed report of the function's progress. Redundant information can be cancelled out by setting reduce.intern=TRUE.
rsaga.hillshade are intended to be more user-friendly interfaces to the most frequently used SAGA modules. These higher-level interfaces support default values for the arguments and perform some error checking; they should therefore be preferred if available.A warning is issued if the RSAGA version is not one of 2.0.4-2.0.8 or 2.1.0-2.1.4
rsaga.env, rsaga.get.libraries, rsaga.get.modules, rsaga.search.modules, rsaga.get.usage; rsaga.esri.wrapper for a wrapper for ESRI ASCII/binary grids; rsaga.hillshade and other higher-level functions.
