hec_two: Query 2d Model Results
In FlowWest/hecr: An R interface to HecRas model outputs

Description Usage Arguments Details Examples

hec_two allows you query a time series from a hec-ras model result using one or more coordinates and an optional time stamp.

1	hec_two(hc, xy, ts_type = "Water Surface", time_stamp = NULL)

`hc`	an hdf file read in with the hec_file() function
`xy`	a coordinate or set of coordinates either in a dataframe or matrix structure. See details below for more information.
`ts_type`	the time series to extract
`time_stamp`	return only values with this timestamp

You can supply coordinates in as a matrix. The matrix must have two columns, the first corresponding to the x the second to y. You can supply a dataframe with two columns, the first for x and the second for y.

## Not run: 
## first read in file
f <- hec_file("examples/ArdenwoodCreek.p50.hdf")

## water surface time series at the coordinate 4567654.0, 2167453.0
ws <- hec_two(f, xy=c(4567654.0, 2167453.0), "Water Surface")

## water surface time series at multiple coordinates
coords <- c(4567654.0, 2167453.0, 3456124.0, 7856124.0)
ws <- hec_two(f, xy=coords, "Water Surface")

## water surface for a fixed timestamp, useful when querying for large amounts of coordinates. 
ws <- hec_two(f, xy=c(4567654.0, 2167453.0), "Water Surface", timestamp="2005-09-12 00:00:00")
