r - Write a dataframe to csv file with value of NA as blank

There is a dataframe named cnbd, for example:

cnbd = data.frame(1,2,3,NA,NA,5)

Thus the expression:

dim(cnbd)[1]

give 1.

I want to write a dataframe like cnbd to a csv with:

write(file = filename, cnbd, append = TRUE)

The problem comes:

  1. The values of csv file show cnbd with 6 rows not 1 row as 1,2,3,NA,NA,5.
  2. I need output cnbd show as 1,2,3,,,5 in csv file, no NAs.

Try this:

write.table(df, "cnbd.csv",
            na = "",
            row.names = FALSE,
            col.names = FALSE,
            append = TRUE,
            sep = ",")
