T_frequency: A function characterizes frequency of stream thermal regime

In tsangyp/StreamThermal: Calculating metrics that characterize stream thermal regime

Description

This function summarize metrics of stream thermal frequency.

Usage

T_frequency(sitedata, cT = 16, TlengthPortion = 2/3, SeasonSp = c(3, 4,
  5), SeasonSu = c(6, 7, 8), SeasonFa = c(9, 10, 11), SeasonWi = c(12, 1,
  2))

Arguments

sitedata	stream monitoring site data in SiteID, Date(in as.Date format), MaxT, MinT, MeanT.
cT	critical temperature of interest, default = 16 (Celsius)
TlengthPortion	portion of length that required for calculating metric summaries, defaulty=2/3
SeasonSp	define spring season, default as March, April, and May, c(3,4,5)
SeasonSu	define summer season, default as June, July, August, c(6,7,8)
SeasonFa	define fall season, default as September, October, November, c(9,10,11)
SeasonWi	define winter season, default as December, Januray, February, c(12,1,2)

Examples

install.packages("dataRetrieval")
library(dataRetrieval)
ExUSGSStreamTemp<-readNWISdv("01382310","00010","2011-01-01","2011-12-31",c("00001","00002","00003"))
sitedata<-subset(ExUSGSStreamTemp, select=c("site_no","Date","X_00010_00001","X_00010_00002","X_00010_00003"))
names(sitedata)<-c("siteID","Date","MaxT","MinT","MeanT")
T_frequency(sitedata)
