Example 2: Rename a Column in a data.table Without Indexing the Column In this section, I’ll demonstrate how to change the name of a column without indexing it. Sometimes, our dataset consists of many columns and we may not be sure which is the number of the column that we want to ...
我有一个实体,它有一个ID字段: @Id @Column(name = "`U##ID_VOIE`") @GeneratedValue(generator = "VOIE_SEQ") private String id; 该类还定义了序列生成器: @SequenceGenerator(name = "VOIE_SEQ", sequenceName = "VOIE_SEQ") Oracle模式具有所需的序列。一切正常。 我们还有测试,它使用内存...

FoldChange(FC,姑且翻译为差异倍数),相同基因在不同样本组(可以是疾病组与正常组,也可以是这里的两个Clusters)中平均表达量差异倍数,是A/B的倍数关系。 常见的差异倍数是将上述平均表达量的倍数关系进行取log2(FC)。 根据对数图像可以发现,当x趋近于0时,y趋近于-∞,因此看到的最终差异倍数往往是log2[(A+1)...

网友给出代码,天了撸,他竟然继续提问,如果要用GO Description而不是Term,该怎么搞,这就是简单的merge而已啊,网友给出的是dplyr的代码,告诉他用left_join。 让我们再翻出来gogadget.gmt函数: gogadget.gmt function(x, genes, genome, id, fetch.cats=c("GO:CC","GO:BP","GO:MF"), file = "cytoscape...
最近遇到如何在boxplot基础上展示两组数据的FoldChange的问题,最后通过结合热图的方式解决了该问题。 加载R包 library(dplyr)library(tibble)library(data.table)library(ggpubr)library(cowplot) 导入数据 phen<-read.csv("phenotype.csv")dat<-read.table("data.txt",header=T,row.names=1,sep="\t") ...
