Read Snapshot files

Reads files from a vector of files and/or folders into a list of dataframes.

Usage

read_snapshot_files(input, except, basepath, verbose = TRUE, logger = NA)

Arguments

input

a character vector of valid paths: can be files and/or folders

except

files to ignore (optional): all paths for (a part of) which match the exact expression in except will be ignored.

basepath

the part of the path that should be ignored when copying final files (i.e. absolute path inside one's comupter that should not be copied in final file.)

verbose

Should messages be displayed when reading a folder/file?

logger

a log4r logger object if you want logging (can be created with create_logger), else NA.

Value

A named list of dataframes. Each element of the list is a dataframe with the contents of a file read from the files list given in input. The names of the list are the file names from the root of input: If the element from input is a file, it is a filename. If the element from input is a folder, it is the relative path from basepath to the file.

Details

The files are assumed to be comma or semicolon-separated CSV. If the filename is MAD_S2_full_report_0-50__agreement_corrected_fin.csv, the function only reads the first 26 columns as this file has empty columns.

Examples

if (FALSE) {
read_snapshot_files("path/to/datafolder/DHP", 
                    basepath = "path/to/datafolder", 
                    except = "DHP/DHP+OVE_same_file/*")
}
