- Received an e-mail issue from Kurt Hornik on 19 August 2023 regarding the use of “@docType package” which is no longer valid. Replaced the iemisc.R file with iemisc-package.R to reflect the requested change.
- Added the
`chem.databases`

package to Imports to replace`CHNOSZ`

which has been removed from Imports - Added
`printr`

to Suggests to allow the printing of help functions in the vignettes & added`tibble`

and`lintr`

to Suggests - Modified the Help section on the README again & Added the additional available function to the README

- Revised the air_stripper function to search for the CAS Number in
the atsdr_tsca_ld50_a data set of the
`chem.databases`

package. Also revised the package to obtain the molecular formulas and average mass from the chem_wiki data set of the`chem.databases`

package - Added the “%inorder%” function to return character vectors in a given sequence
- Added the c_composite_CN function for connected impervious areas
- Added the uc_composite_CN function for unconnected impervious areas
- Replaced the T for temperature variable with Temp for temperature in
all functions after doing a
`lintr`

check on the package to attempt to locate an error causing the references not to be valid in the Manningtrap function - Added an additional contributor for the “%inorder%” function
- Created the Sound Frequencies & Nikola Tesla’s 3-6-9 Theory vignette and modified all other vignettes. The most significant revisions were made in the Comparing Other Hydraulic Software Output to iemisc’s Manningtrap for Critical Conditions & Construction Measurement Examples vignettes

- Modified the Help section and the package introduction on the README
- Revised the non-standard evaluation of library calls to standard evaluation calls in the README and in all functions

- Added the notchin function (Negate chin from
`data.table`

and Negate in from`base`

R) to determine which character or numeric vectors are not in a set of character or numeric vectors - Added the surface_area (for calculating the linear surface area) & rain_garden_driveway (for sizing a rain garden based on driveway surface areas) functions
- Removed
`qdapTools`

from Imports as Prof Brian Ripley sent an e-mail that`qdapTools`

is scheduled for archival on 6 May 2023 due to failing the CRAN checks. The lookupQT (lookup in`qdapTools`

) and lookup_helperQT (lookup_helper in`qdapTools`

) functions have been added to the package to avoid`iemisc`

from being archived on that date too. The existing functions have been modified to use lookupQT instead of lookup.

- CRAN update to move from archived back to active state

`octave`

to`octave eval = FALSE`

in vignettes where GNU Octave was called to avoid the CRAN ERROR message on certain systems where GNU Octave was not present - Added a check in the frac_to_numeric function to issue an error message when the length of n > 1 exists to correct the failed tests on some systems
- Added both author and encoding fields to the various functions where those 2 items were missing [f2, f3, f4, f5, f6, f7, f8, kin_visc_water, lat_long2utm, Manningcircy, Manningtrap_critical, Re2, Re3, Re4]
- Added more assert_that clauses to both the weighted_CN and weighted_C functions
