Convert txt file to dataframe in R

[vinayprakash808]

is there a way to convert txt file data into Dataframe in R

For example, I have a df.txt file in my project folder

df.csv

"a", "e", "b", "c" ,"d", "f"
a 1, e 1, b1 ,c1 ,d1, f1
"a", "e", "b" ,"c" ,"d" ,"f"
a1, e1, sdf, c1 ,d1, f1
"a" ,"e" ,"b", "c", "d" ,"f"
a1 ,e1, sdf, sdf,d1 ,f1
"a", "e", "b" ,"c" ,"d", "f", "z"
a2, e1 ,b1, c1, d1, f1, z1

Expected output

     a    e    b    c    d    f    z   ### column names

    a 1  e 1  b1   c1   d1   f1   NA
    a1   e1   sdf  c1   d1   f1   NA
    a1   e1   sdf  sdf  d1   f1   NA
    a2   e1   b1   c1   d1   f1   z1

library(tidyverse)

df<-read_delim("df.csv",delim=",",quote = "")

names(df)<-str_remove_all(names(df),'"')

names(df)<-str_remove_all(names(df),' ')

df%>%
  filter(row_number()%%2==1)
# 
# # A tibble: 4 x 6
# a     e      b      c      d     f    
# <chr> <chr>  <chr>  <chr>  <chr> <chr>
# 1 "a 1" " e 1" " b1 " "c1 "  "d1"  " f1"
# 2 "a1"  " e1"  " sdf" " c1 " "d1"  " f1"
# 3 "a1 " "e1"   " sdf" " sdf" "d1 " "f1" 
# 4 "a2"  " e1 " "b1"   " c1"  " d1" " f1"

Thanks. But there is another column called Z
