R package that contains Irucka Embry’s miscellaneous USGS functions (processing .exp and .psf files, statistical error functions, “+” dyadic operator for use with NA, creating ADAPS and QW spreadsheet files, calculating saturated enthalpy, etc.). Irucka created these functions while a Cherokee Nation Technology Solutions (CNTS) United States Geological Survey (USGS) Contractor and/or USGS employee.

Installation from CRAN



With credit due to the matlab package, for a complete list of functions and the package DESCRIPTION file, use:

library(help = "ie2misc")



# 1) Calculate the mean-absolute deviation (MAD)
set.seed(1003) # makes the example reproducible

obs1 <- rnorm(1003) # observed

# Using the default value of na.rm = FALSE
# using a matrix of the numeric vector obs1
mat1 <- matrix(data = obs1, nrow = length(obs1), ncol = 1, byrow = FALSE,
dimnames = list(c(rep("", length(obs1))), "Observed"))


# 2) Compute the index of agreement (dr)
set.seed(300) # makes the example reproducible
obs <- rnorm(300) # observed
pre <- rnorm(300) # predicted

# Using the default value of na.rm = FALSE
# using a matrix of the numeric vectors pre and obs
mat <- matrix(data = c(obs, pre), nrow = length(pre), ncol = 2, byrow = FALSE,
dimnames = list(c(rep("", length(pre))), c("Predicted", "Observed")))

dr(mat[, 2], mat[, 1])

# 3) Produce a saturated enthalpy table and direct the output to the console

sat_enthalpy2(elevation = 1810, tbegin = 28, tend = 80, tincrement = 0.1,
output = "console")
# elevation = 120 feet, tbegin = 32 degrees F, tend = 100 degrees F,
# tincrement = 0.1 degrees F

# 4) Create an .xlsx spreadsheet for each of the following water-quality data
# sets (follow the file dialog):

file1 <- ""
file2 <- "&site_no=03584500&referred_module=sw&period=&begin_date=1904-07-01"
file3 <- "&end_date=2016-06-22"
file4 <- paste0(file1, file2, file3) # used to truncate the file name

# Suspended sediment concentration, milligrams per liter (Mean)

file5 <- ""
file6 <- "&site_no=03584500&referred_module=sw&period=&begin_date=1904-07-01"
file7 <- "&end_date=2016-06-22"
file8 <- paste0(file5, file6, file7) # used to truncate the file name

# Suspended sediment discharge, tons per day (Mean)
