Details

In order for these functions to work, the columns of dfin need to be in the correct order. formatLong requires that the columns are in the following scheme:

1. site name or number.
2. date or observation number.
3. response variable (detections, counts, etc).
4. The remaining columns are observation-level covariates.

formatWide requires particular names for the columns. The column order for formatWide is

1. (optional) site name, named “site”.
2. response, named “y.1”, “y.2”, ..., “y.J”.
3. columns of site-level covariates, each with a relevant name per column.
4. groups of columns of observation-level covariates, each group having the name form “someObsCov.1”, “someObsCov.2”, ..., “someObsCov.J”.
