If you used sub() to replace the string, then use gsub() function instead of sub() with the same syntax to replace all occurrences of the character string in the field.

Like below,

gsub("old string","new string",vector)

Ex: To replace Apple instead of apple in a list

list = list("apple","Orange","Banana")

gsub("apple","Apple",list)
