Check directional netwok
The check of directionality of animal networks is not working properly.
The following should give an error.
library(mapMCDA) df <- data.frame( orig = "A", dest = "B", olon = 1, olat = 1, dlon = 2, dlat = 2, stringsAsFactors = FALSE ) tf <- tempfile(fileext = ".csv") write.csv(df, file = tf, row.names = FALSE) read_network(tf) #> IGRAPH e7c95ba DN-- 2 1 -- #> + attr: name (v/c) #> + edge from e7c95ba (vertex names): #>  A->B
On the other hand, we might relax this condition and give a warning instead.
