Extension of EcotoneFinder for space/time series
1 2 3 4 |
data |
A list of dataframes corresponding to the series or a single dataframe with a series factor. Species must appear as columns. |
dist |
A vector or column containing the gradient along which the analysis will be done. Must be of the same lenght as data. |
series |
If data is a single dataframe, must be the name or the number of the factor column identifying the series. |
method |
One of c("dca", "fanny", "vegclust", "diversity", "cmeans", "all"). Tell the function which analysis to perform. See details. |
groups |
Interger. The desired number of clusters if any of the clustering method is selected. |
m.exp |
Integer. The membership exponent for any of the clustering method. |
standardize |
Standardize method to apply to the data before further analysis (for fanny and cmeans). Must be one of decostand methods (see decostand). |
diversity |
diversity indice to be calculated. See details. |
na.rm |
Logical. Should NAs be removed. |
EcotoneFinderSeries is a generalisation of the EcotoneFinder function to handle space/time series of data. If a dataframe is provided, it will convert it internally to a named list according to the factor provided by the series argument. The methods of analysis and standardizations, as well as the diversity indices are the same as those of the EcotoneFinder function.
A list of lists containing the outcomes of the EcotoneFinder function for each series.
