dist.prop {ade4} | R Documentation |
computes for percentage data some distance matrices.
dist.prop(df, method = NULL, diag = FALSE, upper = FALSE)
df |
a data frame containing only positive or null values, used as row percentages |
method |
an integer between 1 and 5. If NULL the choice is made with a console message. See details |
diag |
a logical value indicating whether the diagonal of the distance matrix should be printed by `print.dist' |
upper |
a logical value indicating whether the upper triangle of the distance matrix should be printed by `print.dist' |
returns a distance matrix, object of class dist
