plot_sedFlow: plot_sedFlow. Create plots of sediment vs. discharge for...

In USGS-R/sedReview: A package and shiny GUI for review of discrete water-quality sediment records and box coefficient exploration of data stored in the USGS NWIS system

Description

Function to output scatterplots of sediment parameter vs. discharge. Output is list of plots or write to PDF.

Usage

plot_sedFlow(
  x,
  log.P80154 = FALSE,
  log.P70331 = FALSE,
  log.P80225 = FALSE,
  log.P00530 = FALSE,
  log.Q = FALSE,
  siteSelect = NULL,
  PDFout = NULL
)

Arguments

x	A dataframe output from get_localNWIS
log.P80154	Logical, if TRUE, SSC y axis will be log10. Default is FALSE.
log.P70331	Logical, if TRUE, sand/silt break y axis will be log10. Default is FALSE.
log.P80225	Logical, if TRUE, bedload y axis will be log10. Default is FALSE.
log.P00530	Logical, if TRUE, TSS y axis will be log10. Default is FALSE
log.Q	Logical, if TRUE, flow x axis will be log10 for all parameters present. Default is FALSE.
siteSelect	Character, site number to create plots for if x contains multiple sites. Default is NULL.
PDFout	Character. File or full path name of file for plots. If NULL, the default, a list of the plots will be returned in R instead.

Details

Scatterplots of SSC (P80154), sand/silt break (P70331), bedload (P80225), TSS (P00530) vs. flow (all discharge reported or converted to cfs). Not all parameters need to be present in x for plots to be created (eg. if only SSC present than only SSC vs. flow plot returned)

If PDFout is not specified, than a list of the plots is returned. Plots (if applicable) are specified above. See example for more details.

Value

If PDFout = NULL, list containing ggplot elements. If PDFout specified, a PDF document containing the plots.

Examples

data("exampleData",package="sedReview")
x <- exampleData
sedFlow <- plot_sedFlow(exampleData, siteSelect = "06934500")
## Not run: 
# view plot in Rstudio
sedFlow$SSC

# output to file on D drive
plot_sedFlow(exampleData, siteSelect = "06934500", PDFout = "D:/flow.pdf")

## End(Not run)
