checkFrequenciesFile | R Documentation |
Loads a frequency database file and compares it against mixture data to check for common errors.
checkFrequenciesFile(filename, mix)
filename |
Path of the frequency 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 data frame 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 occurred but could be fixed or that do not prevent
the execution of the program.
error
List of strings describing the errors that occurred that made it impossible to return a valid data frame.
If this list is not empty, then the data frame item will be NULL

# note: the mixture data frame is passed as an argument
# if the previous check failed, the program should not continue
# with the frequencies file check
freqfile <- system.file('extdata','frequencies22Markers.txt',package='relMix')
freqs <- checkFrequenciesFile(freqfile, mix$df)
