R scripts for analyzing Edar and Xedar gene expression data in mouse and rat tail development
This repository contains R scripts for analyzing gene expression data from the study "Differential Expression of Edar and Xedar During Mouse and Rat Tail Appendage Development".
The scripts perform statistical analyses of Edar and Xedar gene expression data, including:
- Data quality control and normalization
- Two-way ANOVA with post-hoc tests
- Correlation analysis
- Polynomial regression modeling
- Data visualization
The following R packages are required:
- stats
- ggplot2
- car
- nlme
##Install using:
"install.packages(c("stats", "ggplot2", "car", "nlme"))"
##Input Data Format
The scripts expect a CSV file named "edar_xedar_expression.csv" with the following columns:
day: developmental day (numeric)
species: mouse or rat (factor)
edar: Edar expression value (numeric)
xedar: Xedar expression value (numeric)
actin: β-actin expression value (numeric)
##Example
day,species,edar,xedar,actin
11,mouse,55.81,1176.26,1.02
12,rat,90.44,1833.53,0.98
##Usage
Place your data file in the working directory
Run the analysis:
source("expression_analysis.R")
##Output
The script generates:
Statistical test results (saved in analysis_results.RData)
Expression pattern plots (saved as PDF)
R-squared values for polynomial models
ANOVA results and correlation coefficients
