If your field separator is for example “|”, it’s possible use the general function read.table() with additional arguments:Ĭoursera - Online Courses and Specialization Data science. In this case, the data frame columns corresponding to string in your text file will be character.įor example: my_data <- lim(file.choose(), If you don’t want your text data to be converted as factors, add stringsAsFactor = FALSE in lim(), read.csv() and read.table() functions. 
If your data contains column with text, R may assume that columns as a factors or grouping variables (e.g.: “good”, “good”, “bad”, “bad”, “bad”). If you use the R code above in RStudio, you will be asked to choose a file.
It’s also possible to choose a file interactively using the function file.choose(), which I recommend if you’re a beginner in R programming:. To know your current working directory, type the function getwd() in R console. The above R code, assumes that the file “mtcars.txt” or “mtcars.csv” is in your current working directory.
