as.data.frame.dist {mefa} | R Documentation |
Converts a 'dist' object into vector and vice versa.
vec2dist(x, size, labels = NULL, diag = FALSE, upper = FALSE, call = FALSE, method = NULL) is.dist(x) ## S3 method for class 'dist': as.data.frame(x, row.names = NULL, optional = FALSE, dim.names = FALSE, ...)
x |
A vector or a 'dist' object. |
size |
Integer, the number of observations in the dataset (see dist ).
|
labels, diag, upper, call, method |
Logical, setting attributes of the distance object (see dist ).
|
row.names |
Row names for the resulting data frame. |
optional |
Argument not yet used. |
dim.names |
Logical, if TRUE , names stored in the Labels attribute of the
dist object are returned as factors instead of row/column indices.
|
... |
Other arguments passed to functions. |
vec2dist
returns an object of class dist
.
is.dist
returns a logical statement about the class of the object.
as.data.frame.dist
returns a data frame with comuns row
for row id's, col

for the distance values.
