Hi, I do not know how to resolve this, but want to flag it for someone who might.
In lesson 9 (ggplot2_pt2), there is a question that states the following:
| Notice that by doing this, ggplot simply ignored the outlier point at
| (50,100). There's a break in the line which isn't very noticeable. Now
| recall that at the beginning of the lesson we mentioned 7 components
| of a ggplot plot, one of which was a coordinate system. This is a
| situation where using a coordinate system would be helpful. Instead of
| adding ylim(-3,3) to the expression g+geom_line(), add a call to the
| function coord_cartesian with the argument ylim set equal to c(-3,3).
The correct answer results in the following error:
Error in obj_is_vector(limits) : could not find function "obj_is_vector"
Importantly, the skip() function fails to work at this section of the lesson, resulting in a loop that the user cannot get out of.
Could not reproduce the error, however, on another computer.
