Edit Question
Title
Body
I have a corpus: txt = "a patterned layer within a microelectronic pattern." I would like to replace the term "pattern" exactly by "form", I try to write a code: txt_replaced = gsub("pattern","form",txt) However, the responsed corpus in txt_replaced is: "a formed layer within a microelectronic form." As you can see, the term "patterned" is wrongly replaced by "formed" because parts of characteristics in "patterned" matched to "pattern". I would like to query that if I can replace the string exactly using gsub()? That is, only the term with exactly match should be replaced. I thirst for a responsed as below: "a patterned layer within a microelectronic form." Many thanks!
