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!
