“Calculate MIMS dissolved gas concentrations without getting a headache.”
mimsy is a data analysis package that transforms raw MIMS (Membrane Inlet Mass Spectrometer) signal data into dissolved gas concentration readings using standard solubility equations. mimsy is designed to be simple and accessible for non-R users.
Click on the Get started tab above to read through the detailed how-to guide.
# Load data into R
data <- read.csv(file = "data.csv", header = TRUE, stringsAsFactors = FALSE)
# Run the mimsy function
results <- mimsy(data, baromet.press = 977.2, units = "hPa")
# Save the results
mimsy.save(results, file = "results.xlsx") # To Excel file
save(results, file = "results.RData") # To RData file
# Done! :)# Pull package from github using devtools
library(devtools)
install_github("michelleckelly/mimsy", dependencies = "Depends")
# Load package into your R environment
