Description
A function to read files with send, receive, and ties format for a multivariate network with the possibility to transform it into an three dimenasional array.
Usage
read.srt(file, header = TRUE, sep = "\t", attr = FALSE , toarray = TRUE, dichot = FALSE, labels = NULL)
Arguments
header
(logical) does the file has a header?
sep
the separator among the columns (default is horizontal tab)
attr
(logical) whether or not the file corresponds to attribute-based data
toarray
(logical) should the data frame be transformed to arrays?
dichot
(logical) should the data be dichotomized?
labels
(optional) labels of the nodes
Value
By default an array; usually with three dimensions of stacked matrices where the multiple relations are placed. If toarray = FALSE, then the data frame is given.
Details
srt stands for send, receive, and ties, and it is a data frame with at least 3 columns for the sender, receiver, and the ties, one column for each type of relation. However, the attr option correspond to a actor and self-ties data frame file with the option to transform it to an identical matrix.
It is also possible to treat the input data as data frame object and manipulate it via e.g. the subset function with the toarray option.
