How to use make.names() function In R Language
We can do this by using make.names() function.
Syntax: make.names(colnames(dataframe))
Where, dataframe is the input dataframe
Example: R program to replace dataframe column names using make.names
R
# create a dataframe with 4 columns and 3 rowsdata = data.frame("web technologies" = c("php","html","js"), "backend tech" = c("sql","oracle","mongodb"), "middle ware technology" = c("java",".net","python"), check.names = FALSE) # replace blank by using make.names print( make.names(colnames(data))) |
Output:
[1] “web.technologies” “backend..tech” “middle.ware.technology”
Replace Spaces in Column Names in R DataFrame
In this article, we will replace spaces in column names of a dataframe in R Programming Language.
Let’s create a Dataframe with 4 columns with 3 rows:
R
# create a dataframe with 4 columns and 3 rowsdata = data.frame("web technologies" = c("php","html","js"), "backend tech" = c("sql","oracle","mongodb"), "middle ware technology" = c("java",".net","python"))# displaydata |
Output:
In the above example, we can see that there are blank spaces in column names, so we will replace that blank spaces
