R语言中拆分字符列行时遇到separate_rows函数不适用于character类对象的报错咨询

Hey there! Let's get that lyric-splitting code working properly. The error you're seeing (no applicable method for 'separate_rows' applied to an object of class "character") happens because separate_rows() (from the tidyr package) expects a data frame as its first input, not a single character vector like Albums$lyric.

The Correct Approach #

Instead of passing just the lyric column directly, feed the entire Albums data frame into separate_rows(), and specify the column name you want to split as the second argument. This way, the function will keep all your other metadata (like album names, track titles, etc.) intact while splitting each lyric line into individual words:

# Load required packages if you haven't already
library(dplyr)
library(tidyr)

# Split lyric rows into individual words, keeping all other columns
Albums_with_individual_words <- Albums %>%
  separate_rows(lyric, sep = " ")

Quick Optional Enhancement #

If you want to clean up the words (removing punctuation, converting to lowercase for easier analysis later), you can add a mutate() step right after:

Albums_cleaned_words <- Albums %>%
  separate_rows(lyric, sep = " ") %>%
  # Remove punctuation and convert to lowercase
  mutate(lyric = tolower(gsub("[[:punct:]]", "", lyric)))

This will give you a tidy data frame where each row is a single word from the lyrics, paired with all the original album/track information from your Albums data frame.
