Ammonium (NH_4) concentration (mg/L) in precipitation measured at Olympic National Park, Hoh Ranger Station (WA14), weekly or every other week from January 6, 2009 through December 20, 2011.
A data frame with 102 observations on the following 6 variables.
Start of collection period. Date on which the sample bucket was installed on the collector.
End of collection period. Date on which the sample bucket was removed from the collector.
a numeric vector indicating the cumulative week number starting from January 1, 2009.
a character vector of the original NH_4 concentrations reported either as the observed value or less than some detection limit. For values reported as less than a detection limit, the value reported is the actual limit of detection or, in the case of a diluted sample, the product of the detection limit value and the dilution factor.
a numeric vector of NH_4 concentrations with non-detects coded to their detection limit.
a logical vector indicating which observations are censored.
