I'm interested in calling a special function from a namespace without the need to load the package. For instance, as described on R-bloggers, the package
"%notin%" <- function(x, table) !(match(x, table, nomatch = 0) > 0)
1:10 mefa4::`%notin%` 7:10
Error: unexpected symbol in "1:10 mefa4"
In addition: Warning message:
package ‘sp’ was built under R version 3.3.2
mefa4::`%notin%` c(7:10, 1:10)
Error: unexpected symbol in "mefa4::'%notin%' c"
