Wish list for improvements

This page logs some things for which the developers have identified as future wishes to add|improve|implement in the MetaboQC package.

1. Implement a ppca(), probabilistic PCA analysis as currently we are imputing missingness in metabolite data as median estimates - for the purposes of the PCA only.
2. Integration of the iPVs package to identify principal variables and a list of "independent" features.
3. Allow user to enter a list of samples that should be excluded from the start (would allow subsets of the data to be processed and also for samples that are known to be poor quality or replicates to be excluded). BUT, would need to consider if any of the steps in the pipeline would be invalidated by only having a subset of the experimental batch.
4. Convert pipeline to tidyverse format.
