check_text function

Check Text For Potential Problems

Uncleaned text may result in errors, warnings, and incorrect results in subsequent analysis. check_text checks text for potential problems and suggests possible fixes. Potential text anomalies that are detected include: factors, missing ending punctuation, empty cells, double punctuation, non-space after comma, no alphabetic characters, non-ascii, missing value, and potentially misspelled words.

check_text(text.var, file = NULL)

Arguments

• text.var: The text variable.
• file: A connection, or a character string naming the file to print to. If NULL prints to the console. Note that this is assigned as an attribute and passed to print.

Returns

Returns a list with the following potential text faults reports:

• non_character- Text that is non-character.
• missing_ending_punctuation- Text with no endmark at the end of the string.
• empty- Text that contains an empty element (i.e., "").
• double_punctuation- Text that contains two qdap punctuation marks in the same string.
• non_space_after_comma- Text that contains commas with no space after them.
• no_alpha- Text that contains string elements with no alphabetic characters.
• non_ascii- Text that contains non-ASCII characters.
• missing_value- Text that contains missing values (i.e., NA).
• containing_escaped- Text that contains escaped (see ?Quotes).
• containing_digits- Text that contains digits.
• indicating_incomplete- Text that contains endmarks that are indicative of incomplete/trailing sentences (e.g., ...).
• potentially_misspelled- Text that contains potentially misspelled words.

Note

The output is a list but prints as a pretty formatted output with potential problem elements, the accompanying text, and possible suggestions to fix the text.
