name

Name of the dataset.

Value

A character string representing the HDF5 storage type (e.g., "float32", "uint32", "string").

Examples

file <- tempfile(fileext = ".h5")

# Write integers
h5_write(file, "integers", 1:5)
# Write doubles
h5_write(file, "doubles", c(1.1, 2.2))

# Check types
h5_typeof(file, "integers") # "uint8" (auto-selected)
#> [1] "uint8"
h5_typeof(file, "doubles")  # "float64" (auto-selected)
#> [1] "float64"
