How to split readLines output into text array R

Question

I am using readLines to read the first 4 lines of csv files to determine what the headers are so I can concatenate files with similar headers. readLines produces difficult output that looks like this (this is only the first line as an example):

output <- readLines(one_min_file, n = 4)

[1] "\"TOA5\",\"Shelton 2SW\",\"CR1000\",\"62704\",\"CR1000.Std.27\",\"CPU:0044-20201101.CR1\",\"35516\",\"OneMinute\""

How do I parse this into a text array or something that looks like this, or the same array that this produces?

c('TOA5','Shelton 2SW','CR1000','62704','CR1000.Std.27','CPU:0044-20201101.CR1','35516','OneMinute')


EDIT:
dput(readLines(one_min_files[h1], n = 1))
"\"TOA5\",\"Shelton 2SW\",\"CR1000\",\"62704\",\"CR1000.Std.27\",\"CPU:0044-20201101.CR1\",\"35516\",\"OneMinute\""

Answer 1

Try removing double quotes and splitting by ,:

(output <- c("\"TOA5\",\"Shelton 2SW\",\"CR1000\",\"62704\",\"CR1000.Std.27\",\"CPU:0044-20201101.CR1\",\"35516\",\"OneMinute\""))
#> [1] "\"TOA5\",\"Shelton 2SW\",\"CR1000\",\"62704\",\"CR1000.Std.27\",\"CPU:0044-20201101.CR1\",\"35516\",\"OneMinute\""

gsub('"', '', output, fixed = TRUE) |> strsplit(",") |> unlist()
#> [1] "TOA5"                  "Shelton 2SW"           "CR1000"               
#> [4] "62704"                 "CR1000.Std.27"         "CPU:0044-20201101.CR1"
#> [7] "35516"                 "OneMinute"

Or parse the line with read.csv():

read.csv(text = output, header = FALSE)[1,] |> unlist() |> unname()
#> [1] "TOA5"                  "Shelton 2SW"           "CR1000"               
#> [4] "62704"                 "CR1000.Std.27"         "CPU:0044-20201101.CR1"
#> [7] "35516"                 "OneMinute"
