R Studio currently has version 0.99.442 out for download. I highly recommend upgrading to the latest version since there has been a lot of new functionality added. Here’s a few snapshots of some of the new features:
There’s built-in debugging icons within R scripts to the left of the line number. For this feature to work properly your script has to be saved (e.g., test.R).
When I hover my mouse over the error I see the message “unexpected token ‘)’ “, which is letting me know I have an extra closed parenthesis. Sweet!
There’s built-in auto-fill for some of the parameters you may be adding to a function. In the image below I’m starting to add ‘xlim’ to specify the x-axis limits of my plot. My full coding might be something like “xlim = c(0, 6)”. Click the image below for a bigger picture so you can read the dialog box.
In the image below, I’m calling the function lm (for linear regression), but I have a comma without another argument. When I hover the mouse over the yellow triangle exclamation point the built-in debugging says there’s a “missing argument to function call”. This Is AWESOME!!!
These are just a few of the new features in R Studio. Get out there and check it out!!!
