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. > dataEXCEL dataEXCEL dfEXCEL <- as.data. > dataSPSS dataSPSS dataStata dataStata dataSAS install.packages(“readxl”) : TRUE if R should convert variables with value labels into R factors with those levels.to.ame: TRUE if R should treat loaded data as a data frame.> dataRDS dataSPACE dataSPACE dataTAB dataCOMMA dataFW install.packages(“foreign”) The command > ls() can be used to print out all of the objects currently loaded into R. The names given to these objects when they were originally saved will be given to them when they are loaded. When R calls load(), all of the R objects saved in the file are loaded into R. Notice that the result of this function is not assigned to an object name. Setting the working directory can eliminate path confusion. When specifying the pathname, R reads forward slashes, whereas Windows reads backward slashes.
