handleMissings {btergm}  R Documentation 
Process NA
values (= remove nodes with NA
s iteratively).
handleMissings(mat, na = NA, method = "remove", logical = FALSE)
mat 
A matrix object. 
na 
The value that missing data are coded as. Usually 
method 
What should be done with the missing data? If

logical 
Return a matrix with logical values indicating which cells should be removed? By default the manipulated matrix is returned. 
This function deals with missing data in matrices or network objects used for
inferential network analysis. It can either remove missing rows and/or
columns iteratively (rows and columns with more NA
values first, then
successively rows and columns with fewer NA
entries) or replace
missing values by the modal value of the matrix or by 0
. The function
can return either the manipulated matrix or a matrix with logical values
indicating which of the cells should be removed.
Either a matrix in which missing data were taken care of or a matrix indicating where missing data are located.
