Take a dataframe containing a column describing sample IDs (col_sample)
Filter on col_sample %in% samples_to_show.
Add any missing samples_to_show not present DF as levels of col_sample.
This way, when plotting we can use scale_x_discrete(drop=FALSE) to display all the samples we care about
Arguments
- data
dataframe with a column describing sample IDs (data.frame)
- col_samples
name of column in
datacontaining sample IDs (character)- samples_to_show
the samples we want to show in plots. These samples should be the only ones represented in data.frame content, and any missing ones will be added as factor levels (character)
