overwrite function

Create function that modifies text elements in a vector

overwrite(..., fixed = TRUE)

Arguments

• ...: Passed to gsub()
• fixed: This is passed to gsub(), but overwrite()'s default behavior is the opposite of the one of gsub(). Default is FALSE which means that strings that are exactly matched will be replaced. This is useful because strings like THETA(1) contains special characters. Use fixed=FALSE to use regular expressions. Also, see other arguments accepted by gsub() for advanced features.

Returns

A function that runs gsub to character vectors

Examples

myfun <- overwrite("b","d")
myfun(c("a","b","c","abc"))
## regular expressions
myfun2 <- overwrite("b.*","d",fixed=FALSE)
myfun2(c("a","b","c","abc"))
