r - How to access (index) a name/column by its name? -



r - How to access (index) a name/column by its name? -

let's assume have

x <- 1:3 names(x) <- c("has", "some", "names")

and want rename 1 of these names, some good. if know index, can this:

names(x)[2] <- "good"

what i'm trying find out how access name "some" name. intuitively:

names(x)["some"] <- "good"

but not work, since names(x) not have "names" (i.e. left hand side null). tried set "names" of names(x):

names(names(x)) <- names(x)

which gives no error, names(x) still not have "names" => still no access text possible... question is: how can set "names of names"?

note: i'm asking educational purposes improve understand how indexing strings works. there ways accomplish without setting "names of names", maybe this:

x <- ifelse(names(x) == "some", "good", names(x))

r indexing
