Question

我发现这个问题与我的相似，但我需要知道一种方法，用数学条件做同样的事情，例如小于或等于或等于或等于（＆lt; =，＆gt; =，＆gt;或＆LT;）

Subsetting a dataframe in R by multiple conditions

关于如何做到这一点的任何想法？

这是我的data.frame

的输入

我希望以一种方式过滤数据框，如果变量“GENProm”＆lt; 0.5和“matricula”> 10，那么我将保留这些观察结果（只是一个随机的例子）。

Answer 1

temp是原始数据集，temp.1是子集化后的数据集。

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

Answer 2

只需将表达式与&（AND）或|（OR）

连接起来

使用subset

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

或者，more safely, [

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

子集具有多于1个条件的data.frames
