order_cols_q takes in a data frame and places the columns specified by first at the front and those by last at the end. If one of first or last are left as NA, they will be ignored.

1	order_cols_q(df, first = NA, last = NA)

`df`	a data frame
`first, last`	character vectors or NA

All ellements of first and last must be in the column names of df and not be NA. first and last may not overlap.

df with its columns reordered

order_cols now uses nonstandard evaluation.

# We'll demonstrate reorder here
library("dplyr")
df = data.frame(a = 1:4,
                b = letters[4:7],
                c = rnorm(n = 4),
                d = rchisq(n = 4, df = 3),
                e = c("Salty", "Sweet", "Subtle", "Sweaty"))
order_cols(df, first = "d", last = c("a","e"))

order_cols(df, last = c("c", "a"))


df 
  filter(a <3) 
  order_cols(c("c","d"))
