Once they save them on their local computer, they have been able to import them into R. ![]() In rare cases, I have had to email data sets to students as.XLSX file, and then import it as an XLSX file into RStudio (third option on the Import dataset drop down menu). Another option is to download the data file as an.Some of these download problems are solved by downloading using Chrome as your browser instead of Safari. When downloading a data set to a Mac, sometimes the extension for the data file gets changed to. Students using Macs sometimes have difficulties that vary with the age and type of computer they are using.CSV files using a PC is generally not a problem, although occasionally there are problems if one is using Chrome as their browser. Note that this R command uses an uppercase "V", although most commands use lower case. You can also review it using the "View()" command in R, e.g., View(framstudy) and then hitting the "Run" button in the upper left window. You can review the data set at any time by clicking on the tab with its name in the upper left window or by clicking on the data set name in the upper right window. The data set is also now listed in the window at the upper right and indicates that it has 49 observations and 6 variables. Notice also that R has created a tab just below the main menu with the title for the data set (framstudy in this case). When the data is imported, R should show the data in the upper left window of the R Studio, and you can scroll right and left and up and down to check the data set for errors. Then click on the "Import" button at the bottom of this window. All of the PH717 data sets have headings, so make sure "Yes" is selected.

Then, to view the data set in the upper left window, you can use the command View(fram), noting that this particular commaned uses an uppercase "V", although most are lowercase. Once you double click on the data file to select it, it will import the data set and give it the nickname "fram" in this case, a nickname that I chose just to allow less typing when referring to the data set. If you click on the highlighted selection on the taskbar, it will open the dialog box in the previous image, and you can browse to locate and select the data file. Note that the window may not fully open, but might appear on your taskbar at the bottom of your screen if you are using a PC (see the brown highlghted selection on my taskbar in the image below.

The older method for importing data sets in to use the read.csv(file.choose()) command. If the data set is posted on a website, first save it to your local computer and then import it. data <- read.table(file = "my_file.Data sets that are saved on your local computer can be imported into R. You can read it with the following code if you want to also display the header (column names). ![]() Sep = "", # Separator of the columns of the fileĭec = ".") # Character used to separate decimals of the numbers in the fileĬonsider, for instance, that yo have a TXT file called my_file.txt and you have put it in your R working directory. Header = FALSE, # Whether to display the header (TRUE) or not (FALSE) ![]() read.table(file, # TXT data file indicated as string or full path to the file This basic syntax affects to almost all TXT data files. In the following subsections we will explain two more ( skip and skipNul) if needed, but in case you want to know all the arguments you can find them in the read.table function documentation or calling ?read.table. Importing TXT into R rarely needs more arguments than specified. You can read a TXT file in R with the read.table function.
