A set of function to test conformance with LAS specifications
Tools reserved to developpers and not intended to be used by regular users. The functions return TRUE or FALSE by default without more information. If behavior is 'warning' functions throw a warning for each fail and return FALSE if any warning TRUE otherwise. If behavior is 'stop' functions throw an error for the first fail and return TRUE if 0 error. If behavior is 'vector' returns a character vector with the decription of each error an never fail. Is it useful to make a detailed inspection.

header |
a list containing the header of a las file |
behavior |
character. Defines the behavior of the function. 'bool' returns TRUE or FALSE. 'warning' throw a warning for each fails and return FALSE if any warning TRUE otherwise. 'vector' returns a character vector of each warning but does not thrown any warning. |
data |
a data.frame or a data.table containing a point cloud |
