Convert sparse matrix to data.frame — sparse2df • scMiko

Convert sparse matrix to data.frame. Developed to handle large datasets, by constructing data.frame block-by-block.

sparse2df(mat.sparse, block.size = 10000, transpose = F, verbose.error = F)

Arguments

mat.sparse: Sparse matrix.
block.size: If large dataset, construct data.frame column-wise block-by-block, where block size is specified by numeric block.size parameter. Default is 10000.
transpose: Logical specifying whether to transpose data.
verbose.error: Logical specifying whether to print error message in case of large dataset which requires block-by-block construction.

Value

data frame

Examples


# Get sparse matrix
exp.mat <- so@assays[[current.assay]]@data
#> Error in eval(expr, envir, enclos): object 'so' not found

# convert to data.frame
df <- sparse2df(mat.sparse, transpose = T)
#> Error in sparse2df(mat.sparse, transpose = T): could not find function "sparse2df"
