Also learned how to use a select() function from the dplyr package. The example includes removing columns by name, index, from the list based on conditions e.t.c. In this article, you have learned different ways to remove a single column/variable and several columns/variables in the R data frame. Nevertheless, reticulate allows you the flexibility of having both R and Python together without leaving RStudio. The package authors suggest using a Python editor for Python-only projects. The following is a complete example of how to remove a single column/variable or several columns/variables from the R DataFrame (ame) The RStudio IDE is a set of integrated tools designed to help you be more productive with R and Python. There are different ways to use Python in RStudio’s IDE, including sourcing Python scripts, that can be found in the reticulate documentation. If a column is not found, it returns a warning.ġ. Similarly, use -ends_with() to remove variables that end with a text, the following examples remove name and price columns as they end with the letter e.įinally, use the one_of() function to check if the column exists and then remove it from the data frame only when exists. The following example removes the column chapters as it starts with character c. In terms of data analysis and data science, either approach works. Contrast this to the LinearRegression class in Python, and the sample method on Dataframes. As we saw from functions like lm, predict, and others, R lets functions do most of the work. Use -starts_with() to ignore columns that start with a text. R is more functional, Python is more object-oriented. This function also takes a list of values to check contains. The following example removes the column chapters as it contains text apt. Use -contains() to ignore columns that contain text. The same function can also be used to remove variables by name range. This pipe can be used to write multiple operations that you can read left-to-right. For example, x %>% f(y) converted into f(x, y) so the result from left-hand side is then “piped” into the right-hand side.
