![]() ![]() ![]() If you save it in a variable called my_file, you will be able to access the variables or the data you want. If you just execute the previous code you will print the data frame but it will not be stored in memory, since you have not assigned it to any variable. ![]() In order to load a CSV file in R with the default arguments, you can pass the file as string to the corresponding function. The following table summarizes the three main default arguments: Function As you may find datasets with both characteristics, you can use the corresponding function instead of changing the parameters of the arguments. In the second case, in order to create CSV files the semicolon is needed if some numbers are decimals. You can also set a new working directory using the setwd () function. You can check which directory the R workspace is pointing to using the getwd () function. The read.csv () function is used to read the CSV file available in your current working directory. You may have noticed that the only difference between the functions are the separator of the values and the decimal separator, due to in some countries they use commas as decimal separator. To read a CSV file in R, use the read.csv () function. Read.csv2(file, header = TRUE, sep = " ", quote = "\"", dec = ",",įill = TRUE, comment.char = "", encoding = "unknown". # Semicolon as separator and comma as decimal point by default Header = TRUE, # Whether to read the header or notįill = TRUE, # Whether to fill blacks or notĬomment.char = "", # Character of the comments or empty stringĮncoding = "unknown", # Encoding of the file Read.csv(file, # File name or full path of the file # Comma as separator and dot as decimal point by default For additional details remember to type ?read.csv or ?read.csv2. You can see the basic syntax of the functions with the most common arguments in the following code block. In this section you will learn how to import a CSV file in R with the read.csv and read.csv2 functions. ![]()
