daily_frequency_table: Daily frequency table

In USGS-R/HASP: Hydrologic AnalySis Package

Daily frequency table

Description

Calculates the historical max, mean, minimum, and number of available points for each day of the year

Usage

daily_frequency_table(
  gw_level_dv,
  gwl_data,
  parameter_cd = NA,
  date_col = NA,
  value_col = NA,
  approved_col = NA,
  stat_cd = NA
)

Arguments

gw_level_dv	data frame, daily groundwater level data from readNWISdv
gwl_data	data frame returned from dataRetrieval::readNWISgwl, or data frame with mandatory columns lev_dt (representing date), lev_age_cd (representing approval code), and a column representing the measured value (either lev_va, sl_lev_va, or value).
parameter_cd	If data in gw_level_dv comes from NWIS, the parameter_cd can be used to define the value_col. If the data doesn't come directly from NWIS services, this can be set to NA,and this argument will be ignored.
date_col	the heading of the date column. The default is NA, which the code will try to get the column name automatically.
value_col	name of value column. The default is NA, which the code will try to get the column name automatically.
approved_col	name of column to get provisional/approved status.
stat_cd	If data in gw_level_dv comes from NWIS, the stat_cd can be used to help define the value_col.

Value

a data frame giving the max, mean, min, and number of available days of data for each day of the year.

Examples

# site <- "263819081585801"
p_code_dv <- "62610"
statCd <- "00001"
# gw_level_dv <- dataRetrieval::readNWISdv(site, p_code_dv, statCd = statCd)
gw_level_dv <- L2701_example_data$Daily
daily_frequency_table(gw_level_dv,
                      NULL,
                      parameter_cd = "62610")

gwl_data <- L2701_example_data$Discrete
daily_frequency_table(gw_level_dv,
                      gwl_data,
                      parameter_cd = "62610")
