glmmSeq

This R package is designed to model gene expression with a general linear mixed model (glmm). This allows us to include random effects as well as fixed effects. For the purpose of the package we use the glmer function from the lme4 package which fits a glmm.

This package focuses in particular on changes in genes expression between different response or treatment groups over time.

Loading the package

From CRAN

install.packages("glmmSeq")

From Github

devtools::install_github("KatrionaGoldmann/glmmSeq")

Locally

You can also download the source directory and load the functions individually:

functions = list.files("./R", full.names = TRUE)
invisible(lapply(functions, source))

But you will need to load in the additional libraries then:

# Install CRAN packages
invisible(lapply(c("MASS", "car", "ggplot2", "ggpubr", "lme4", 
                     "methods", "parallel", "plotly", "stats", 
                     "gghalves"),
                 function(p){
                   if(! p %in% rownames(installed.packages())) {
                     install.packages(p)
                   }
                   library(p, character.only=TRUE)
                 }))

# Install BioConductor packages
if (!requireNamespace("BiocManager", quietly = TRUE))
  install.packages("BiocManager")
invisible(lapply(c("qvalue"), function(p){
  if(! p %in% rownames(installed.packages())) BiocManager::install(p)
  library(p, character.only=TRUE)
}))

Example script
