iaaR (indoor air analysis in R) is just a grouping of different functions that generally littered my R scripts. They have been combined into a package to allow me to help neaten scripts and provide others with the utilities combined herein.
Upon installing this package and attaching, tidyverse will additionally be installed and attached (if not already). This package can be used without tidyverse, but certain functions like confidence_interval work efficiently using pipelines within dplyr, and so to allow for this flexibility tidyverse is installed and attached as standard. This can be opted out of when attaching iaaR.

Sample analysis
- Calculate instrument limits (LOD/LOQ) with
instrument_limits - Detect noise regions with
detect_noise(intended for use on chromatographic data to remove peaks, but can also be flipped to isolate peaks)

Practical applications
- Calculate the pressure drop in horizontal or vertical pipes for both turbulent or laminar flow with
pressure_drop - Convert volumetric flow rate of a fluid in a pipe to mean velocity with
f2v
- Calculate the pressure drop in horizontal or vertical pipes for both turbulent or laminar flow with
You can install the development version of this package from GitHub using the devtools package:
