Analysis of Variance (ANOVA)
Description
ANOVA_app()
function opens an interactive and user friendly Shiny application that enables users to perform Analysis of Variance (ANOVA) for multi-trait experimental data based on the Randomized Block Design (RBD) by uploading an Excel file.
Usage
ANOVA_app()
Details
The application is designed to perform ANOVA for datasets based on the Randomized Block Design (RBD).
Users can upload an Excel file (.xlsx or .xls) containing data for multiple traits. After uploading the file, users need to click the "Analyze" button.
Results are presented in a tabular format showing sources of variation, their respective degrees of freedom (Df), and the Mean Sum of Squares for each trait. Significance is also indicated.
The output table is downloadable in CSV format.
Value
Opens a user-friendly interactive shiny application for performing ANOVA on experimental data.
Data Format
The uploaded Excel file should be formatted as follows:
First column: Replication
Second column: Genotypes
Subsequent columns: Trait values (e.g., DBH, PH, FW, SW, KW, OC)
Trait names should be concise. Example:
DBH : Diameter at Breast Height
PH : Plant Height
FW : Fruit Weight
SW : Seed Weight
KW : Kernel Weight
OC : Oil Content
Note: The uploaded file name should not contain spaces. For example, use Sample_Data.xlsx
instead of Sample Data.xlsx
.
An example Excel file is available for download using the Download Example Data
button within the application.
The example dataset includes:
170 genotypes
3 replications for each genotype
6 traits: DBH, PH, FW, SW, KW, OC
