前提:接着上述R脚本输出的seed结果来选择应该使用哪个seed比较合理,上个R脚本名字:
“5utr_计算ABD中Ge1和Lt1的个数和均值以及按照TE个数小的进行随机100次抽样.R”
1.输入数据:“5utr-5d做ABD中有RG4和没有RG4的TE之间的T检验.csv”
2.代码:“5utr_5d_ABD中有RG4和无RG4的TE之间的T检验函数+保存符合要求的seed+保存符合要求的数据框+绘制boxplot.R”
setwd("E:\\R\\Rscripts\\5UTR_extended_TE")

# 读取数据
data <- read.csv("5utr-5d做ABD中有RG4和没有RG4的TE之间的T检验.csv", na.strings = "#N/A")
