Problem loading Manipulating Data with dplyr module in the Getting and Cleaning Data course

[DaphniaDoc]

I have tried to install in swirl and from my hard drive and I get the same error message: Attempting to load lesson dependencies...

| Package ‘dplyr’ loaded correctly!

Error in yaml.load(readLines(con, warn = readLines.warn), error.label = error.label, : (C:/Users/daniellec/OneDrive - Lacerta Therapeutics, Inc/Documents/R/R-4.1.2/library/swirl/Courses/Getting_and_Cleaning_Data/Manipulating_Data_with_dplyr/lesson.yaml) Scanner error: while scanning a tag at line 205, column 9 did not find expected whitespace or line break at line 205, column 19

I hit the same error. Here is how I got around it.

Execute the step in the instructions 'install_from_swirl("Getting and Cleaning Data")'.

Then edit the file lesson.yaml. Replace lines 203 thru 205 with the following. (My version of lesson.yaml is attached as lessonbn.yaml.txt.) lessonbn.yaml.txt

  CorrectAnswer: '!is.na(c(3, 5, NA, 10))'
  AnswerTests: omnitest('!is.na(c(3, 5, NA, 10))')
  Hint: \!is.na(c(3, 5, NA, 10)) will negate the previous command, thus telling us what is NOT NA.

You will notice that line 203 has the example in single quote marks and in line 205 the bang (!) is escaped with a backslash (\).

Save the file and continue with the rest of the instructions.

You might have to start swirl() more than once to get past the function deprecation message. This tells me the lesson needs to be edited to work with R Studio 4.1.2.

Thank you very much! That works well!

This was a great helps, thanks!
