Convert the type of a matrix

Convert the type of a matrix

Usage

convert_matrix_type(matrix, type = c("uint32_t", "double", "float"))

Arguments

matrix

IterableMatrix object input

type

One of uint32_t (unsigned 32-bit integer), float (32-bit real number), or double (64-bit real number)

Value

IterableMatrix object

Examples

mat <- matrix(rnorm(50), nrow = 10, ncol = 5)
rownames(mat) <- paste0("gene", seq_len(10))
colnames(mat) <- paste0("cell", seq_len(5))
mat <- mat %>% as("dgCMatrix") %>% as("IterableMatrix")
mat
#> 10 x 5 IterableMatrix object with class Iterable_dgCMatrix_wrapper
#> 
#> Row names: gene1, gene2 ... gene10
#> Col names: cell1, cell2 ... cell5
#> 
#> Data type: double
#> Storage order: column major
#> 
#> Queued Operations:
#> 1. Load dgCMatrix from memory
