Reads one or more variables from a NetCDF file and returns a named list of data.frames (one per variable). Each data.frame contains the coordinate columns (e.g., lon/lat/time) plus a single value column (optionally renamed).
Usage
read_netcdf(
nc_path,
var = NULL,
var_name = NULL,
keep_leap_day = TRUE,
drop_all_na = TRUE,
spatial_ref = "spatial_ref",
signif_digits = NULL,
verbose = FALSE
)Arguments
- nc_path
Character. Path to NetCDF file.
- var
Character vector or NULL. Variables to read. If NULL, reads all non-coordinate variables (and excludes `spatial_ref` if present).
- var_name
NULL, or named character vector. - If named: names are original variable names and values are new names. Renaming applies to output list names and the value-column name.
- keep_leap_day
Logical. If FALSE and time is convertible to Date, removes Feb 29 rows.
- drop_all_na
Logical. If TRUE, drop variables whose values are all NA after applying _FillValue/missing_value handling.
- spatial_ref
Character. Name of a spatial reference variable to ignore when auto-selecting variables (common in CF/CRS-encoded files).
- signif_digits
Integer or NULL. If provided, rounds numeric values via signif(x, signif_digits).
- verbose
Logical. If TRUE, prints basic progress messages.
