rename columns in r code example
Example 1: r rename columns
# 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
Example 2: how to change column names in r
colnames(dataset) <- c('name1','name2',..)
Example 3: R rename singl edf column
colnames(trSamp)[2] <- "newname2"
Example 4: rename column in r
my_data %>%
rename(
sepal_length = Sepal.Length,
sepal_width = Sepal.Width
)
Example 5: rename column in 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'
Example 6: rename columns based on a variable in r
df <- rename(df, new_name = old_name) #For renaming dataframe column
tbl <- rename(tbl, new_name = old_name) #For renaming tibble column
tbl <- tbl %>% rename(new_name = old_name) #For renaming tibble column using dplyrpipe
#operator
