exceed

Description

Determines if water data contains observations that exceed a upper and/or lower assessment points.

Usage

exceed(
  object,
  parkcode = NA,
  sitecode = NA,
  charname = NA,
  category = NA,
  points = "both",
  lower = NA,
  upper = NA,
  all = F,
  catsum = F,
  ...
)

Arguments

`object`	One of a `Characteristic` object, a `Site` object, a `Park` object or a list of such objects.
`parkcode`	One or more parkcodes, in quotes. If `object` is a `Park` object or a `list` of `Park` objects, then the `parkcode` argument can be used to select which sites should be used.
`sitecode`	One or more sitecodes, in quotes. If `object` is a `Park` object or a `list` of `Park` or `Site` objects, then the `sitcode` argument can be used to select which sites should be used.
`charname`	Name of one or more characteristics, in quotes. Only those characteristics will be returned.
`category`	One or more categories of characteristics, in quotes. Only those categories of characteristics will be returned.
`points`	What assessment points to use when determining if there are exceedances. There are three options "lower" Only assess the data against the lower reference point "upper" Only assess the data against the upper reference point "both" The default. Assess the data against both reference points
`lower, upper`	The lower and uppers assessment points. Either a number specified by the user, or if `NA`, the default, the assessment point is determined by the `LowerPoint` and `UpperPoint` slots in the `Characteristic` objects.
`all`	Logical, defaults to `FALSE`. Not used when `object` is a `data.frame`. If `all` is `FALSE` characteristics without upper or lower references points will not be included in the results. If `all` is `TRUE` such characteristics will be included.
`catsum`	Logical, defaults to `False`. When true summarizes by category rather than a characteristic. Not used if `object` is a `data.frame`
`...`	Additional commands passed to `getWData` for filtering or subsetting the data.
