R/qgis_filterverticesbym.R
qgis_filterverticesbym.RdQGIS Algorithm provided by QGIS (native c++) Filter vertices by M value (native:filterverticesbym). Filters away vertices based on their m-value, returning geometries with only vertex points that have a m-value ≥ the specified minimum value and ≤ the maximum value. If the minimum value is not specified then only the maximum value is tested, and similarly if the maximum value is not specified then only the minimum value is tested. Depending on the input geometry attributes and the filters used, the resultant geometries created by this algorithm may no longer be valid.

)source - Input layer. Path to a vector layer.
number - Minimum. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
number - Maximum. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
sink - Filtered. Path for new vector layer.
further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
