In my project folder, there is a csv file with 3 columns. (A, B and C) There is a dataframe (df) in my R console with same columns. Is there a way to cbind df to csv?

Here column A and B is same

For example

#csv file
A  B     C
1  Ca   trww
2  gf   dfsd
3  gh   fgdfg

df
A  B     C
1  Ca   new_trww
2  gf   new_dfsd
3  gh   new_fgdfg

new csv file should be

A  B     C          C1
1  Ca   trww      new_trww
2  gf   dfsd      new_dfsd
3  gh   fgdfg     new_fgdfg

do a merge, `merge(csv_file, df, by = c("A", "B"))` – Maël May 09 '22 at 08:32
here we have to read the csv file first right? Can we not write it to csv without reading it? – manu p May 09 '22 at 08:41
Yes, read the csv first and assign it to object `csv_file` – Maël May 09 '22 at 08:42
