pgirmess: Spatial and Seasonal Analysis Tools for Field Ecologists

A set of tools for reading, writing, and transforming spatial and seasonal data, developed by Patrick Giraudoux. It includes functions for spatial interpolation, polyline discretization, linking observations, and statistical tests for ecologists. The package also provides miscellaneous utilities such as inference on diversity indexes and writing data frames with Chinese characters.

Use Cases

• Interpolating regular point positions between landmarks based on spatial transformation functions
• Discretizing polylines into regular point positions for spatial analysis
• Performing statistical inference on diversity indexes mentioned in the description
• Linking distant observations to specific points for spatial correlation studies
• Converting bounding boxes into spatial objects for mapping and analysis

Strengths

• Includes a specific set of tools for spatial and seasonal data transformation
• Provides functions for model selection and statistical tests tailored for ecology
• Offers utilities for handling data with Chinese characters

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Last update date is unknown; freshness unverified
