The R block enables you to use R language programs in a Workflow. To use the R block, you must have a R interpreter installed and configured.
The following demonstrates how the R block can be used to restrict an input lib_books.csv dataset (which contains observations that describe a range of books available from a lending library) to only show authors.
Output_1 <- data.frame(Author=Input_1$Author)
A green execution status is displayed in the Output port of the R block and the new Working Dataset. The dataset contains only the Author column from all observations in the input lib_books.csv dataset.
