checkFrequenciesFile: Load and check a frequency file
In relMix: Relationship Inference for DNA Mixtures

Description Usage Arguments Details Value Author(s) See Also Examples

Loads a frequency database file and compares it against mixture data to check for common errors.

1	checkFrequenciesFile(filename, mix)

`filename`	Path of the frecuency database file
`mix`	Data frame with mixture data. See relMix vignette for description of the format

The mixture data is used to perform more advanced checks, such as to make sure all alleles present in the mixture file have an entry in the frequency database. If warnings are found, the function attempts to fix them and explains what it has done in the warning messages. If an error is found, checking stops and a NULL dataframe is returned. The error is described in the error messages.

A list containing

df Data frame with frequencies
warning List of strings describing the errors that ocurred but could be fixed or that do not prevent the execution of the program.
error List of strings describing the errors that ocurred that made it imposible to return a valid data frame. If this list is not empty, then the dataframe item will be NULL

# if the previous check failed, the program should not continue
# with the frequencies file check
