hdf5TFIDF {compartmap} | R Documentation |
Transform/normalize compartment calls using TF-IDF on HDF5-backed objects
hdf5TFIDF(h5, scale.factor = 1e+05, return.dense = FALSE, return.se = FALSE)
h5 |
SummarizedExperiment object, DelayedMatrix, or a normal matrix |
scale.factor |
Scaling factor for the term-frequency (TF) |
return.dense |
Whether to return a dense, in memory matrix |
return.se |
Whether to return the TF-IDF matrix as a new assay in the SummarizedExperiment |
A TF-IDF transformed matrix of the same dimensions as the input
m <- 1000 n <- 100 mat <- round(matrix(runif(m*n), m, n)) #Input needs to be a tall matrix tfidf <- hdf5TFIDF(mat)
