fline |
sf data.frame NHD Flowlines with comid, pathlength, lengthkm, hydroseq, levelpathi, rpuid, vpuid, and arbolatesu (dnhydroseq is required if tocomid is not provided). |
vpu |
character e.g. "01" |
include_null_rpuid |
logical default TRUE. Note that there are some flowlines that may have a NULL rpuid but be included in the vector processing unit. |

data.frame containing subset network
Examples
source(system.file("extdata/sample_data.R", package = "nhdplusTools"))
