[R] cleanup/replacing a value on condition of another value

[Dr Eberhard W Lisse]

Thanks.

Your method

    mutate(
       cases = ifelse(
          country == 'Namibia'
             & type == 'confirmed'
             & date == '2021-10-23'
             & cases == 357,
          NA,
          cases
       )
    )

works, as does Rui's

    mutate(
       cases = replace(
          cases,
          which(country == 'Namibia'
             & type == 'confirmed'
             & date == '2021-10-23'
             & cases == 357),
          NA
       )
    )

Thank you both, again.
