[R] deleting column from data frame

[Marianne Promberger]

Hi Knut,

> test <- data.frame("X"=c(1:4),"Y"=c(5:8),"Z"=c(8:11))
> test <- test[,-2]
> 
> Is there a way to specify the col name  "Y" to delete instead the number?


test[,colnames(test)!="Y"] 

test[,!colnames(test)%in%"Y"] 

test[,-grep("Y",colnames(test))]
