R rename data frame columns
Raw
gistfile1.r
d <- data.frame(alpha=1:3, beta=4:6, gamma=7:9)
# alpha beta gamma
# 1 4 7
# 2 5 8
# 3 6 9
names(d)
# "alpha" "beta" "gamma"
The simplest way is to use rename() from the plyr package:
rename(d, c("beta"="two", "gamma"="three"))
# alpha two three
# 1 4 7
# 2 5 8
# 3 6 9
