I tried to run the "Manipulating data with dplyr" course and the following happened-
| Please choose a course, or type 0 to exit swirl.
1: Getting and Cleaning Data
2: R Programming
3: Take me to the swirl course repository!
Selection: 1
| Please choose a lesson, or type 0 to return to course menu.
1: Manipulating Data with dplyr
2: Grouping and Chaining with dplyr
3: Tidying Data with tidyr
4: Dates and Times with lubridate
Selection: 1
| Attempting to load lesson dependencies...
| This lesson requires the ‘dplyr’ package. Would you like me to install it for you
| now?
1: Yes
2: No
Selection: 1
| Trying to install package ‘dplyr’ now...
package ‘dplyr’ successfully unpacked and MD5 sums checked
| Could not install package ‘dplyr’!
| | 0%Error in seq.default(0, 1, length.out = nrow(e$les)) :
argument 'length.out' must be of length 1
| Leaving swirl now. Type swirl() to resume.
Although I have the dplyr package installed already but in any case "| Leaving swirl now. Type swirl() to resume.", this is what I get I don't understand the meaning of this error message..
I want to complete this course. Any help will be appreciated. Thanks!
