Here are some alternatives:

1) setNames

setNames(data.frame(1:11), "colname")

2) names<-

"names<-"(data.frame(1:10), "colname")

2a) names(...)<-

DF <- data.frame(1:11)
names(DF) <- "colname"

3) structure This one mucks with the internal structure and is not really recommended but has been added since it is possible to do.

structure(data.frame(1:11), .Names = "colname")

4) dimnames

as.data.frame(matrix(1:11, dimnames = list(NULL, "colname")))
