This package contains functions that import, manage, or manipulate hydrologic data and functions that apply specialized transformations used in hydrologic analyses amd modeling. A listing of the functions and their description is in the following table.

Function	Description
%cn%	Identify character strings that contain the specified pattern.
anomalies	Break down time-series data into long- and short-term deviations (anomalies)
	and the high-frequency variation.
as.timeDay	Convert data to objects of class "timeDay."
baseDay	Computes the "base" day of the year, a reference value that can be used to
	group days for the computation of summary statistics.
boxCox	Apply a Box-Cox power transformation.
coalesce	Merge a matrix or list of vectors selecting the first non-missing value.
conc.meq	A list containing necessary information for the function conc2meq.
conc2meq	Convert concentration in milligrams per liter to milli-equivalents per liter.
daysInMonth	The number of days in a month.
dectime	Convert dates and times to decimal time in years.
dectime2Date	Convert decimal time in years to an object of class "Date."
dlpearsonIII	The density of the log-Pearson Type III distribution.
dms2dd	Convert data in degrees, minutes, and seconds to decimal degrees.
dpearsonIII	The density of the Pearson Type III distribution.
eventLen	Compute the length or duration of an event.
eventNum	Compute the number of an event, identified by a TRUE value in a sequence.
eventSeq	Compute the sequence number within an event.
eventSeries	Create regular time-series data from recorded events.
exportCSV	Export a data frame to a comma-separated values file.
exportRDB	Export data to an ASCII relational-database file.
fillMissing	Interpolate missing values in a regular time-series of data.
fourier	Compute the Fourier series decomposition from date data.
group2row	Unstack data oriented in columns to rows of data.
hyperbolic	Apply a hyperbolic transformation.
hysteresis	Compute a basis for estimating hysteresis effect in some variable related to
	the argument x.
IboxCox	Apply the inverse Box-Cox power transformation.
Ihyperbolic	Apply the inverse hyperbolic transformation.
importCSV	Import a data frame from a comma-separated values file.
importRDB	Import a data frame from an ASCII relational-database file.
index.coalesce	Return the index column number instead of the values for the first non-missing value.
isCharLike	Determine whether the data be treated like character data.
IsCurve	Apply the inverse s-curve transformation.
isDateLike	Deterimne whether the data can be treated like date data.
isGroupLike	Determine whether the data can be treated like grouping data.
isNumberLike	Determine whether the data can be treated as numeric data.
makeMeta	Create a template meta file for a comma-separated values file.
mergeNearest	Merge two datasets by the nearest date and time.
mergeQ	Merge flow data with water-quality data.
miss2na	Convert a coded missing value to NA.
more	Display the contents of an object by pages.
movingAve	Compute the moving average in regular time-series data.
movingDiff	Compute the moving difference in regular time-series data.
na2miss	Convert NA to a coded missing value.
peaks	Compute the indices of peaks in time-series data.
pick	Select a value based on the value of a logical, integer, or character reference value.
plpearsonIII	Compute the cumulative probability of the log-Pearson Type III distribution.
ppearsonIII	Compute the cumulative probability of the Pearson Type III distribution.
qlpearsonIII	Compute the quantile of the log-Pearson Type III distribution.
qpearsonIII	Compute the quantile of the Pearson Type III distribution.
quadratic	Compute a basis for an orthogonal second-order polynomial.
readList	Import data arranged on lines into a list.
recode	Recode distinct values.
regularSeries	Put data collected at arbitrary times into a regular time series.
rlpearsonIII	Compute the random variates of the log-Pearson Type III distribution.
rpearsonIII	Compute the random variates of the Pearson Type III distribution.
sCurve	Apply the s-curve transformation.
scaleRng	Scale data to a specified range.
screenData	Screen data for missing values or gaps.
seasons	Create seasonal categories from dates.
seqCollapse	Collapse a sequence of integers to a compact character string.
setFileType	Support function to manage file suffixes.
setTZ	Set the time zone information for dates and times.
shiftData	Shift time-series data forward or backward.
sumComposition	Compute the percentages of data within a matrix.
timeDay	Various methods for manipulating time-of-day data, including conversion to and
	from character, addition, and others.
untable	Expand a 2-dimensional table into the raw values.
waterYear	Compute the water year of date data. The water year ends on September 30 of the year.
whichRowCol	Identify the row and column indexes for TRUE values in a logical matrix.
