rangeFill

rangeFill,SpatRaster-method

Fill layers with cell-varying ranges defined by a start and end SpatRaster. The range must start at 1 and end at a user-defined maximum.
For example, for a cell with <code>start=3</code>, <code>end=5</code> and with <code>limit=8</code>, the output for that cell would be <code>0,0,1,1,1,0,0,0</code>

spatial

Methods for spatial data analysis with vector (points, lines, polygons) and raster (grid) data. Methods for vector data include geometric operations such as intersect and buffer. Raster methods include local, focal, global, zonal and geometric operations. The predict and interpolate methods facilitate the use of regression type (interpolation, machine learning) models for spatial prediction, including with satellite remote sensing data. Processing of very large files is supported. See the manual and tutorials on <https://rspatial.org/> to get started. 'terra' replaces the 'raster' package ('terra' can do more, and it is faster and easier to use).

rangeFill function

<dl><dt>x</dt>
<dd>SpatRaster with at two layers. The Cell values of the first layer indicate the start of the range (1 based); the cell values are indicate the end of the range</dd>
<dt>limit</dt>
<dd>numeric &gt; 1. The range size</dd>
<dt>circular</dt>
<dd>logical. If <code>TRUE</code> the values are considered circular, such as the days of the year. In that case, if first &gt; last the layers used are c(first:limit, 1:last). Otherwise, the range would be considered invalid and <code>NA</code> would be used</dd>
 <dt>filename</dt>
<dd>character. Output filename</dd>
<dt>...</dt>
<dd>additional arguments for writing files as in <code>writeRaster</code></dd>
</dl>
