Plot a time series of parameters in a swmpr object

Usage

## S3 method for class 'swmpr'
plot(x, type = "l", ...)

## S3 method for class 'swmpr'
lines(x, ...)

x	input swmpr object
type	chr string for type of plot, default 'l'. See plot.

The swmpr method for plotting is a convenience function for plotting a univariate time series. Conventional plotting methods also work well since swmpr objects are also data frames. See the examples for use with different methods.

## get data
data(apadbwq)
swmp1 <- apadbwq

## subset
dat <- subset(swmp1, select = 'do_mgl', 
 subset = c('2013-07-01 00:00', '2013-07-31 00:00'))

## plot using swmpr method, note default line plot
plot(dat)

## plot using formula method
plot(do_mgl ~ datetimestamp, dat)

## plot using default, add lines
plot(dat, type = 'n')
lines(dat, col = 'red')
