overwrite: Create function that modifies text elements in a vector...

In NMsim: Seamless 'Nonmem' Simulation Platform

Create function that modifies text elements in a vector Namely used to feed functions to modify control streams using 'NMsim()' arguments such as 'modify'. Those functions are often onveniently passed a function. 'add' and 'overwrite' are simple shortcuts to creating such functions. Make sure to see examples.

Description

Create function that modifies text elements in a vector Namely used to feed functions to modify control streams using 'NMsim()' arguments such as 'modify'. Those functions are often onveniently passed a function. 'add' and 'overwrite' are simple shortcuts to creating such functions. Make sure to see examples.

Usage

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.

Value

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"))
