The Error in nchar(x): ‘nchar()’ requires a character vector occurs when you are trying to use the nchar() function on a non-character object, such as a numeric or logical vector.
To fix the error, ensure that the object you are passing to the “nchar()” function is a “character vector”.
If the object is not already a character vector, you can use the as.character() function to convert it to a character vector before applying the nchar() function.
Understanding the data type of the object you are working with is crucial in avoiding such type-related errors.
Reproduce the error
factor_var <- factor(c("apple", "banana", "cherry"))
factor_chars <- nchar(factor_var)
print(factor_chars)
Output
Error in nchar(factor_var) : 'nchar()' requires a character vector
Execution halted
How to fix it
factor_var <- factor(c("apple", "banana", "cherry"))
factor_chars <- nchar(as.character(factor_var))
print(factor_chars)
Output
