sample()R语言中的函数根据函数调用中提供的参数创建随机样本。它接受一个向量或一个正整数作为函数参数中的对象。 用法: sample(x, size, replace) 参数: x:表示向量或正整数或 DataFrame size:表示要采集的样本大小 replace:表示逻辑值。如果为 TRUE,样本可能有多个相同的值 要了解更多可选参数,请在控制台中使...

sample_n()R语言中的函数用于从 DataFrame 中随机抽取样本。 用法:sample_n(x, n) 参数: x:数据帧 n:要选择的项目的大小/数量 范例1: # R program to collect sample data# from a data frame# Loading librarylibrary(dplyr)# Create a data framed <- data.frame( name = c("Abhi","Bhavesh","C...
Gene expression matrices were processed using Seurat 4.0 in R-programming language. Our cumulative RGC dataset includes six collections (Exp0 was Unlabeled, Exp1-5 were CMO-labeled). The data was curated by a series of QC filters resulting in a total RGC number of 41,782 cells. For QC, ...
