Creating formula using very long strings in R

Question

I\'m in a situation where I have a vector full of column names for a really large data frame.

Let\'s assume: x = c(\"Name\", \"address\", \"Gender\", ......, \

Answer 1

You may try reformulate

 reformulate(setdiff(x, 'class'), response='class')
 #class ~ Name + address + Gender

where 'x' is

  x <- c("Name", "address", "Gender", 'class')

If R keywords are in the 'x', you can do

   reformulate('.', response='class')
   #class ~ .
