r - How to rename backticked contained column names in dplyr -

i have following tibble:

library(tidyverse) df <- structure(list(`input paired-end (star)` = c(9394981, 100), `multi-mapped pair (star)` = c(1493691,  400), `uniquely mapped paired-end (star)` = c(6826405, 200),      `unmapped pair (star-appx)` = c(1074885, 300)), class = c("tbl_df",  "tbl", "data.frame"), row.names = 1:2, .names = c("input paired-end (star)",  "multi-mapped pair (star)", "uniquely mapped paired-end (star)",  "unmapped pair (star-appx)")) 

that looks this:

# tibble: 2 × 4   `input paired-end (star)` `multi-mapped pair (star)` `uniquely mapped paired-end (star)` `unmapped pair (star-appx)` *                     <dbl>                      <dbl>                               <dbl>                       <dbl> 1                   9394981                    1493691                             6826405                     1074885 2                       100                        400                                 200                         300 

how can rename column too:

foo        bar    qux     gop 9394981 6826405 1074885 1493691  100     200      300      400 

an easy option setnames can incorporated chain

library(dplyr) df %>%      setnames(., c('foo', 'bar', 'qux', 'gop'))
