I need to load an excel spreadsheet file to Rstudio in my research. But I have no idea how to do it. Please solve this problem of mine, and advice me.
There are many packages in RStudio to load excel files. Such as: XLConnect, gdata, xlsx package, Readxl package.
You can use these packages mentioned above, and you can also read_excel function in the readxl package. It does not rely on Java.
