Applying dplyr's rename to all columns while using pipe operator

Question

I\'m working with an imported data set that corresponds to the extract below:

set.seed(1)
dta <- data.frame(\"This is Column One\" = runif(n = 10),
               


        

Answer 1

Set column names with the pipe like so:

iris %>% `colnames<-`(c("newcol1", "newcol2", "newcol3", "newcol4", "newcol5"))

Which returns

    newcol1 newcol2 newcol3 newcol4    newcol5
1       5.1     3.5     1.4     0.2     setosa
2       4.9     3.0     1.4     0.2     setosa
3       4.7     3.2     1.3     0.2     setosa
