Practice Programming Assignment: swirl Lesson 7: Matrices and Data Frames

[bayniyazov0518]

Since we have six columns (including patient names), we'll need to first create a vector containing one element for each column. Create a character vector called cnames that contains the following values (in order) -- "patient", "age", "weight", "bp", "rating", "test".

Hi, i think this is the correct answer:

cnames <- c("patient", "age", "weight", "bp", "rating", "test") # create the character vector with the names

colnames(my_data) <- cnames # assign the cnames vector to the data frame you created earlier

my_ data # see the results

I hope this helps :)

(i am a beginner following the steps. this worked for me, i hope it's okay)
