Just to verify for you that this is where the file is located, while R is running, let’s go ahead and go look in our Mac. 5:31 Skip to 5 minutes and 31 seconds Inside my finder, if I click on my downloads, I’ll see 2008.csv, and, if I wanna see the full path of that file, I can hold on the command and click on the name of the folder at the top.
Aug 10, 2020 The version of macOS offered by macOS Recovery might vary in some cases: If macOS Sierra 10.12.4 or later has never been installed on this Mac, Option-Command-R installs the macOS that came with your Mac, or the closest version still available. And Shift-Option-Command-R isn't available. If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery might.
Feb 26, 2018 To update RStudio, go to the RStudio website and download the latest version for Mac. Once it’s downloaded, drag it into Applications folder (that’s how it is at the time of this posting) and allow it to replace your existing RStudio version. That’s pretty much all you need to do. To be double sure you can click on Help - Check for.
In this case, R-Studio for Mac can scan the hard disk trying to find previously existing partitions and recover files from found partitions. From hard disk with bad sectors. R-Studio for Mac can first copy the entire disk or its part into an image file and then process the image file. This is especially useful when new bad sectors are. Shut down your Mac, turn it on while holding down Command+R. Your Mac will boot into the recovery partition. If you’re using an older Mac (from 2010 or earlier), there’s a chance that you can’t use Recovery Mode. On those devices, hold “Option” while turning your computer on, then select the recovery partition instead.
Another way of importing data interactively into R is to use the Clipboard to copy and paste data. To import data from the Clipboard, use the readClipboard() function. For example, select cells B2:B4 in the periodic table spreadsheet, press Ctrl+C to copy those cells to the Clipboard, and then use the following R code:
As you can see, this approach works very well for vector data (in other words, a single column or row of data). But things get just a little bit more complicated when you want to import tabular data to R.
To copy and paste tabular data from a spreadsheet, first select a range in your sheets (for example, cells B1:D5). Then use the readClipboard() function and see what happens:
This rather unintelligible result looks like complete gibberish. If you look a little bit closer, though, you’ll notice that R has inserted lots of “t” elements into the results. The “t” is the R way of indicating a tab character — in other words, a tab separator between elements of data.

The backslash in “t” is called an escape sequence.
The very powerful read.table() function imports tabular data into R. You can customize the behavior of read.table() by changing its many arguments. Pay special attention to the following arguments:
file: The name of the file to import. To use the Clipboard, specify file = “clipboard”.
sep: The separator between data elements. In the case of Microsoft Excel spreadsheet data copied from the Clipboard, the separator is a tab, indicated by “t”.
header: This argument indicates whether the Clipboard data includes a header in the first row (that is, column names). Whether you specify TRUE or FALSE depends on the range of data that you copied.
stringsAsFactors: If TRUE, this argument converts strings to factors. It’s FALSE by default.
Although R offers some interactive facilities to work with data and the Clipboard, it’s almost certainly less than ideal for large amounts of data. If you want to import large data files from spreadsheets, you’ll be better off using CSV files.
