pg2DNAbin: Convert SQL Query Result to DNAbin
In heibl/megaptera: MEGAPhylogeny Techniques in R

Convert a data frame as returned by dbGetQuery to an object of class DNAbin, possibly with confidence scores.

1	pg2DNAbin(pg, label, confid.scores, col.confid = 0, row.confid = 0)

`pg`	A data frame as returned by `dbGetQuery`.
`label`	A vector of mode `"character"` giving the attributes for constructing the sequences labels, e.g. `"taxon"`, `"acc"`, or both.
`confid.scores`	A vector of mode `"character"` specifying if and how confidence scores will be returned. Use `"ignore"` to omit confidence scores. Other options are `"all"`, `"row.means"`, and `"col.means"`. Confidence scores are returned as an attribute and can be accessed by `attr(obj, "cs")`.
`col.confid`	A real number in the interval `[0, 1]` giving the confidence threshold for alignment columns (i.e. nucletide positions); only rows (i.e. taxa, sequences) or columns scoring equal or greater to `min.confid` will be selected.
`row.confid`	A real number in the interval `[0, 1]` giving the confidence threshold for alignment rows (i.e. taxa, sequences); only rows scoring equal or greater to `min.confid` will be selected.
