Example code used for multi-study meta-analysis

These R codes were used to merge counts tables for IDEP1 analysis

R code ```

#Load libraries

library(tidyverse)

library(data.table)

#Set working directory setwd("New_Plant_Matrix")

URLs<-c("https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-120_rna_seq_Normalized_Counts.csv?version17", "https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-38_rna_seq_Normalized_Counts.csv?version12", "https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-37_rna_seq_Normalized_Counts.csv?version11", "https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-321_rna_seq_Normalized_Counts.csv?version4", "https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-218_rna_seq_Normalized_Counts.csv?version10")

destFiles<-c("https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-120_rna_seq_Normalized_Counts.csv?version17", "https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-38_rna_seq_Normalized_Counts.csv?version12", "https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-37_rna_seq_Normalized_Counts.csv?version11", "https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-321_rna_seq_Normalized_Counts.csv?version4", "https://genelab-data.ndc.nasa.gov/genelab/static/media/dataset/GLDS-218_rna_seq_Normalized_Counts.csv?version10")

#Download files from URLs and save them to destination files

for (i in 1:length(URLs)){ download.file(URLs[i], destFiles[i]) }

PlantMetaMatrix <- read_csv("destFiles") ```
