To get the list of column names of dataframe in R we use functions like names() and colnames(). In this section we will be looking on how to get the list of column names in the dataframe with an example
Let’s first create the dataframe.
df1=data.frame(State=c('Arizona','Georgia', 'Newyork','Indiana','seattle','washington','Texas'),
code=c('AZ','GA','NY','IN','ST','WT','TX'),
Score=c(62,47,55,74,31,77,85))
df1
So the dataframe will be
Get the List of column names in R (Method 1):
Get the list of column names using the function colnames()
# method 1 colnames(df1)
Result:
[1] “State” “state_code” “Score”
Get the List of column names in R (Method 2):
Get the list of column names using the function names()
# method 2 names(df1)
Result:
[1] “State” “state_code” “Score”
