Error in editor(file = file, title = title)

[TGeurts]

I'm currently following the swirl course "Regression Models". In the middel of my course I get the error

Error in editor(file = file, title = title) : 
  argument "name" is missing, with no default

Leaving swirl now. Type swirl() to resume.

I've done several other modules without any problem. I am using RStudio Version 0.99.893 under Windows 7 (64-bit) Professional and R version 3.2.4 Revised (2016-03-16 r70336) "Very secure dishes".
I have uninstall all lessons, removed the swirl package. reinstalled the swirl package, installed the course. Problem persists.

Point in the course I get the problem:

|========================================================                                                        |  50%

| Now extract the slope from fit$coef and put it in the variable ols.slope; the slope is the second element in the
| fit$coef vector, fit$coef[2].

> ols.slope <-fit$coef[2]

| You're the best!

  |============================================================                                                    |  53%

| Now we'll show you some R code which generates the left and right sides of this equation.  Take a moment to look it
| over. We've formed two 6-long vectors of variations, one for the slope and one for the intercept. Then we have two
| "for" loops to generate the two sides of the equation.

Error in editor(file = file, title = title) : 
  argument "name" is missing, with no default

Any ideas how to fix this?

Thanks,
Ton.

Thanks for the link to the solution, Sean.

Before you start swirl in RStudio, try entering options(editor = "internal"). Please let me know if that improves your situation.

It works for me as well.

Thanks,
Ton
