incidenceMatrix {sparrow} | R Documentation |
Generates an inidcator matrix to indicate membership of genes (columns)
to gene sets (rows). If y
is provided, then the incidence is mapped
across the entire feature-space of y
.
incidenceMatrix(x, y, ...)

(optional) A target (expression) object |

parameters passed down into |
incidence matrix with nrows = number of genesets and columns are
featureIDs. If y
is passed in, the columns of the returned value
match the rows of y
.
