[R] Removing a space from a string

[cpoiw@rt m@iii@g oii chemo@org@uk]

This RegEx would do it I think:  \s(?=.*\s\d*\.)

Looks for space - \s
Before any strings followed by space, numbers, period

text <- "STR ING 01.  Remainder of the string"

stringr::str_replace_all(text, "\\s(?=.*\\s\\d*\\.)", "")

Should do it I think!
