"Error in kmeans(na.omit(reduced_data_numeric, 5)) : 'centers' must be a number or a matrix" message when attempting to knit an Rmd as a HTML

I am presented with an error message when trying to knit an Rmd script. I have tried to drop any NA's from the data being used for lines 363-364 but this did not work. It is annoying because the k-means has been run and I have been able to plot using some simple code, but for some reason it won't knit. This was the original code that worked:

KM <- kmeans(reduced_data_numeric, 5)

Here is the Code I am trying to use in order for it to knit:

KM <- kmeans(na.omit(reduced_data_numeric, 5))

Here is the message shown in 'output' section when trying to render the HTML knit:

Quitting from lines 363-364 (Movies-Analysis.Rmd) 
Error in kmeans(na.omit(reduced_data_numeric, 5)) : 
  'centers' must be a number or a matrix
Calls: <Anonymous> ... withVisible -> eval_with_user_handlers -> eval -> eval -> kmeans
Solution

  • You've included the number of centers as an argument for na.omit rather than kmeans.

    Note where the parenthesis are at the end of this line and where the 5 is:

    KM <- kmeans(na.omit(reduced_data_numeric), 5)
