Hi Duncan,

There is no way to have pattern be a regular expression and replacement

Backslash is the only special character in replacement. If you need a

I noticed this issue in stringr::str_replace, but it also affects sub()
in base R.
If the pattern in a call to one of these needs to be a regular
expression, then backslashes in the replacement text are treated specially.
For example,
gsub("a|b", "\\", "abcdef")
gives "def", not "def"

1) manipulate wpi_def_nic2004 and wpi_def_nic2008 first so that the data are
compatible, then join them.
2) The full_join statement should explicitly state the columns to join by.

I was trying to splice two wholesale price index deflators series which

to 2012), and another is called wpi_def_nic2008(from 2012 to 2019). I am
trying to create a single series such that the base year prices are
