Write (updated) values back into existing HDF5 datasets (robust for your hdf5r build)

Source: R/hdf5_read-write.R
h5_write_values.Rd

  • Scalars: write with required args (args=list() or args=1L fallback).

  • 2-col TS (data.frame/tibble): expects Nx2 in R; writes as 2xN in HDF5 (RAINDROP style), using explicit hyperslab args=list(1:2, 1:N) to avoid empty selections.

  • If TS length changes and dataset maxdims blocks resize, the dataset is deleted via parent$link_delete(name) and recreated with dims=2xN (fixed), then written. (No maxdims argument used; compatible with your create_dataset signature.)

Usage

h5_write_values(
  h5,
  values,
  resize = TRUE,
  strict = TRUE,
  ts_cols = c("time", "value"),
  scalar_strategy = c("error", "first", "collapse"),
  collapse_sep = ";",
  ts_dtype = "double",
  verbose = FALSE
)

Arguments

h5

Open hdf5r::H5File.

values

Named list; names are dataset paths (leading // allowed).

resize

Logical. If TRUE tries set_extent() where possible.

strict

Logical. If TRUE stop on first error else warn and continue.

ts_cols

Character(2). Column names for TS (default time/value).

scalar_strategy

"error"|"first"|"collapse".

collapse_sep

Separator for collapse.

ts_dtype

Either an H5T object or one of "double","float","integer","logical".

verbose

Logical.

Value

Invisibly, written paths.
