calculates the overlap on the basis of the concept of the 'weighted mean day'
1 |
data1 |
data.frame; abundance dataset. Needs a column with only date objects and one with only numerics. If CheckData = TRUE those need to be named $Date and $Count. |
data2 |
data.frame; abundance dataset. Needs a column with only date objects and one with only numerics. If CheckData = TRUE those need to be named $Date and $Count. needs to have the levels $Date and $Count if CheckData = FALSE. |
CheckData |
logical; If TRUE the CheckData() function will be runned in advance. |
calculates the overlap on the basis of the concept of the 'weighted mean day' by dividing the difference of wmd by the square-root of the sum of the squared standard deviations of both datasets.
