How to use colnames In R Language
By using this function we can get column names. We have to iterate through for loop to get all the column names.
Syntax:
for (iterator in colnames(dataframe)){
print(iterator )
}
where
- dataframe is the input dataframe
- iterator is a variable is used to iterate the elements
Example:
R
# create dataframe with 4 columnsdata = data.frame(column1=c(23, 45), column2=c(50, 39), column3=c(33, 45), column4=c(11, 39))# displayprint(data)# display column namesfor (i in colnames(data)){ print(i)} |
Output:
