Header=TRUE specifies that the data includes a header and sep=”,” specifies that the values in data are separated by commas. The above code reads the file airquality.csv into a data frame airquality. In this case, data is in the form of a CSV file named airquality.csv which can be downloaded from here airquality = read.csv('airquality.csv',header=TRUE, sep=",") Now, load the file with the help of the read command. Setwd(path of the folder where the file is located) In case of an External data source (CSV, Excel, text, HTML file etc.), simply set the folder containing the data as the working directory with the setwd() command.To load the built-in dataset into the R type the following command in the console: data(airquality) Ozone(mean parts per billion), Solar.R(Solar Radiation), Wind(Average wind speed), Temp(maximum daily temperature in Fahrenheit), Month(month of observation) and Day(Day of the month) This dataset consists of more than 100 observations on 6 variables i.e. We shall be using one such dataset called the air quality dataset, which pertains to the daily air quality measurements in New York from May to September 1973. Built-in datasets refer to the datasets already provided within R.> 1 1 > ‘hello World’ hello world Loading in the Dataĭatasets can either be built-in or can be loaded from external sources in R.
