First row as column names in a list of data frames(2)

Question

I want to rename the columns of every data frame in my list of data frames with the first row.

I tried the code from this question First row as column names in a list of data frames but it returns first_row_name=rows_number /c(date=3)/

dflist1 <- lapply(dflist, function(x){
  names(x) <- x[1,]
  x <- x[-1,]
  return(x)
})

What does the first row look like? Could you paste some sample data? Are there any weird characters in the first row? — Sven, Jul 09 '19 at 14:16
`x[-1,]` likely comes back as a data frame--subsetting a data frame gets you another data frame. You need to turn it into a vector to supply it to `names` — camille, Jul 09 '19 at 14:41

The issue is because the columns were factor. So, we unlist and convert to character class

names(x) <- as.character(unlist(x[1,]))
