I have two different character vectors in R, that I want to combine to use for column names:
groups <- c("Group A", "Group B")
label <- c("Time","Min","Mean","Max")
When I try using paste I get the result:
> paste(groups,label)
[1] "Group A Time" "Group B Min" "Group A Mean" "Group B Max"
Is there a simple function or setting that can paste these together to get the following output?
[1] "Group A Time" "Group A Min" "Group A Mean" "Group A Max" "Group B Time"
[6] "Group B Min" "Group B Mean" "Group B Max"
Probably outer
helps your work. Try this:
> c(t(outer(groups, label, paste)))
[1] "Group A Time" "Group A Min" "Group A Mean" "Group A Max" "Group B Time" "Group B Min"
[7] "Group B Mean" "Group B Max"
outer
外(组,标签,FUN =粘贴)
既然它是两个元素数组,我会这样做
c(paste(groups[1],label),paste(groups[2],label))
