This module reads datasets from several input files, merges them and writes the resulting dataset to outfile.
Usage
cdo_merge(ifiles, skip_same_time = NULL, names = NULL, ofile = NULL)
cdo_mergetime(ifiles, skip_same_time = NULL, names = NULL, ofile = NULL)Arguments
- ifiles
Character vector with the path to the input files.
- skip_same_time
BOOL - Skips all consecutive timesteps with a double entry of the same timestamp.
- names
STRING - Fill missing variable names with missing values (union) or use the intersection (intersect).
- ofile
String with the path to the output file.
Value
Operators that output one or more files return a character vector to the output files.
Operators that output an indefinite number of files return a string with the basename of the files.
Operatos that don't return filenames return a character vector with the string output.
Details
merge Merge datasets with different fields
Merges time series of different fields from several input datasets. The number
of fields per timestep written to outfile is the sum of the field numbers
per timestep in all input datasets. The time series on all input datasets are
required to have different fields and the same number of timesteps.
The fields in each different input file either have to be different variables
or different levels of the same variable. A mixture of different variables on
different levels in different input files is not allowed.
mergetime Merge datasets sorted by date and time
Merges all timesteps of all input files sorted by date and time.
All input files need to have the same structure with the same variables on
different timesteps. After this operation every input timestep is in outfile
and all timesteps are sorted by date and time.
