For each row return the column name of the largest value
...make examples using sample reproducible):
DF <- data.frame(V1=c(2,8,1),V2=c(7,3,5),V3=c(9,6,4))
colnames(DF)[apply(DF,1,which.max)]
[1] "V3" "V1" "V2"
A faster solution than using apply might be max.col:
colnames(DF)[max.col(DF,ties.method="first")]
#[1] "V3" "V1" "V2"

An alternative solution that mimics the behavior of this function and would be more appropriate for inclusion within a function body:
new.data <- data[ which( data$V1 > 2 | data$V2 < 4) , ]

ai2starter46有什么优缺点，，还有什么地方是可以优化的
优点是它是最终的兜底方案，对于学生教学场景，功能测试要求不高、或不想受游戏App干扰、或商业模拟器安装不了，推荐使用AI2Starter模拟器。
