Add column to tibble in R - getting 'Error in is.data.frame(.data) : argument ".data"-CodePudding

Hi I have the below code for the purpose of adding a column called 'Area' with value 'Cambridge' for each row of a table. I'm then looking to select 3 columns and place the 'Area' column as the first column.

    TableOutput <- TableOutput %>%
  add_column(Area = "Cambridge") %>%
  select(Area, age, rollingRate) %>%
  relocate(Area, .before = age)

I get the below error, can anyone advise please? Thank you.

Error in is.data.frame(.data) : argument ".data" is missing, with no default

CodePudding user response：

It is just an issue with sign which is probably copying the code directly from the console. The code should be without the

iris %>%
    add_column(Area = "Cambridge")

Error in is.data.frame(.data) : argument ".data" is missing, with no default

Now, check with

iris %>%
    add_column(Area = "Cambridge")

-output
