Statistical Inference>Unable to resume Power lesson #390

Open freyreeste opened 6 years ago

freyreeste commented 6 years ago

I need to resume the lesson but it seems that my session was closed with some error because now it leaves swirl atomatically. Quote "

Would you like to continue with one of these lessons?

1: Regression Models Introduction to Multivariable Regression 2: Statistical Inference Power 3: No. Let me start something new.

Selection: 2

| Package ‘reshape2’ loaded correctly!

| Package ‘ggplot2’ loaded correctly!

Error in z * sigma : non-numeric argument to binary operator

| Leaving swirl now. Type swirl() to resume."

Is there a way to solve this without lossing my lessons progress?
