我发现这个问题与我的相似,但我需要知道一种方法来处理数学条件,例如小于或等于或大于或等于(<=、>=、> 或 <)。

通过多个条件对 R 中的数据框进行子集化

关于如何做到这一点的任何想法?

这是我的 data.frame 的输入

我想以某种方式过滤数据框,如果变量“GENProm”<0.5 和“matricula”>10,那么我将保留这些观察结果(只是一个随机示例)。

temp是原始数据集,temp.1是子集后的数据集。

temp.1 <- temp[temp[,"GENProm"]<0.5 & temp[,"matricula"]>10,]

只需用&(AND) 或|(OR)连接表达式

使用subset

 subset(DF, GENProm < 0.5 & matricula > 10)

或者,更安全的是,[

DF[DF[['GENProm']] < 0.5 & DF[['matricula']] > 10, ]
