findDynGenes: find genes expressed dynamically
In pcahan1/epoch: Dynamic GRN reconstruction from single cell RNA-Seq data

uses slingshot approach

findDynGenes(
  expDat,
  sampTab,
  path = NULL,
  group_column = "dpt_groups",
  pseudotime_column = "pseudotime",
  method = "gam",
  expRaw = NULL
)

`expDat`	properly normalized expression matrix
`sampTab`	sample table that includes pseudotime, rownames = cell_name, and a group column
`path`	vector of group names to include
`group_column`	column name in sampTab annotating groups in the path
`pseudotime_column`	column name in sampTab annotating pseudotime or latent time
`method`	method to find dynamic genes. Defaults to "gam", if "tradeseq", must provide expRaw
`expRaw`	raw expression matrix, required if method="tradeseq"
