Ejemplo 1: r renombrar columnas
# 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
Ejemplo 2: R renombrar columna edf individual
colnames(trSamp)[2] <- "newname2"
Ejemplo 3: r renombrar columnas
library(plyr)
rename(d, c("beta"="two", "gamma"="three"))
#> alpha two three
#> 1 1 4 7
#> 2 2 5 8
#> 3 3 6 9
Ejemplo 4: cambiar el nombre de la columna en r

rename(
sepal_length = Sepal.Length,
sepal_width = Sepal.Width
)
Ejemplo 5: cambiar el nombre de la columna en r
# df = dataframe
# old.var.name = The name you don't like anymore
# new.var.name = The name you want to get
names(df)[names(df) == 'old.var.name'] <- 'new.var.name'
