In ceas: Cellular Energetics Analysis Software

Get mean and confidence intervals from energetics mixed-effects models

Description

Runs linear mixed-effects models on the ATP measure columns from get_energetics with replicates as the random-effect. Estimates mean and confidence intervals for ATP production from glycolysis and OXPHOS at points defined in partition_data

Usage

energetics_lme_summary(atp_col, energetics, conf_int, ci_method)

Arguments

atp_col	The column name of the ATP measure - one of "ATP_basal_resp", "ATP_max_resp", "ATP_basal_glyc", "ATP_max_glyc"
energetics	a data.table of Seahorse OCR and ECAR rates (from get_energetics)
conf_int	The confidence interval percentage. Should be between 0 and 1
ci_method	The method used to compute confidence intervals for the mixed-effects model: "Wald", "profile", or "boot" passed to lme4::confint.merMod().

Value

a data.table with mean and the confidence interval bounds by experimental group

Examples

rep_list <- system.file("extdata", package = "ceas") |>
  list.files(pattern = "*.xlsx", full.names = TRUE)
seahorse_rates <- read_data(rep_list, sheet = 2)
partitioned_data <- partition_data(seahorse_rates)
energetics <- get_energetics(
  partitioned_data,
  ph = 7.4,
  pka = 6.093,
  buffer = 0.1
)
# Only for one column. For the full energetics table run
# `get_energetics_summary` with `model = "mixed"`.
energetics_lme_summary(
  "ATP_max_resp",
  energetics,
  conf_int = 0.95,
  ci_method = "Wald"
)
