- Опубликовано: 14 июл 2024
- Importing data from a CSV-file into R can be easily achieved with a couple of lines of code.
In this tutorial I'll show the read.csv() and read.csv2-function and its functionality to import data from .csv into an R data frame. I'll also show how to only import a certain sheet and within only a certain range of data as well as other helpful arguments like deleting whitespace, setting NA values and so forth.
