# Rename column by name: change "beta" to "two"
names(d)[names(d)=="beta"] <- "two"
d
#> alpha two gamma
#> 1 1 4 7
#> 2 2 5 8
#> 3 3 6 9
# You can also rename by position, but this is a bit dangerous if your data
# can change in the future. If there is a change in the number or positions of
# columns, then this can result in wrong data.
# Rename by index in names vector: change third item, "gamma", to "three"
names(d)[3] <- "three"
d
#> alpha two three
#> 1 1 4 7
#> 2 2 5 8
#> 3 3 6 9
