RSAGA (version 0.94-5)

rsaga.get.version: Determine SAGA GIS version

Description

Determine SAGA GIS version.

Usage

rsaga.get.version(env = rsaga.env(version = NA), ...)

Arguments

env

list, setting up a SAGA geoprocessing environment as created by rsaga.env. Note that version=NA ensures that rsaga.env won't call rsaga.get.version itself.

...

additional arguments to rsaga.geoprocessor

Value

A character string defining the SAGA GIS (API) version. E.g., "2.0.8".

Details

The function first attempts to determine the SAGA version directly through a system call saga_cmd --version, which is supported by SAGA GIS 2.0.8+. If this fails, saga_cmd -h is called, and it is attempted to extract the version number of the SAGA API from the output generated, which works for 2.0.4 - 2.0.7.

Examples

## Not run: 
# myenv <- rsaga.env()
# myenv$version
# # rsaga.env actually calls rsaga.get.version:
# rsaga.get.version()
# 
# # I keep several versions of SAGA GIS in SAGA-GIS_2.0.x folders:
# myenv05 = rsaga.env(path = "C:/Progra~1/SAGA-GIS_2.0.5", version = NA)
# # Check if it's really version 2.0.5 as suggested by the folder name:
# rsaga.get.version(env = myenv05)
# ## End(Not run)
