This function changes multiple colnames of a df there is a range match option

1 2	df.name.change(df, original_names, new_names, range_match = F, fixed = F, invert = F)

`df`	a data.frame
`original_names`	a colname/ an array of colnames you want to change
`new_names`	a target colname/ an array of target colnames, must match the number of names in original_names
`range_match`	just like in Excel match(,,1), default is False
`fixed:`	only applicable if range_match = T, used in grep, please see grep for purpose
`invert:`	only applicable if range_match = T, used in grep, please see grep for purpose, essentially making original_names columns you do not want to change name

range_match True test data set
df <- flat_data
original_names <- c("households", "Installed")
new_names <- c("TV.households","Installed.base")
range_match = T
range_match False test data set
df <- mtcars
original_names <- c("mpg","disp","wt")
new_names <- c("test1","test2","test3")
range_match = F
