getWeights {MOFA} | R Documentation |
Extract the weights from the model.
getWeights(object, views = "all", factors = "all", as.data.frame = FALSE)
object |
a trained |
views |
character vector with the view name(s), or numeric vector with the view index(es). Default is "all". |
factors |
character vector with the factor name(s) or numeric vector with the factor index(es). |
as.data.frame |
logical indicating whether to return a long data frame instead of a list of matrices.
Default is |
By default it returns a list where each element is a loading matrix with dimensionality (D,K),
where D is the number of features and K is the number of factors.
Alternatively, if as.data.frame
is TRUE
,
returns a long-formatted data frame with columns (view,feature,factor,value).
