This is my first here on the forum basically I am really embarrass to ask this question as it should be very easy but I cannot find anything relating to it on the internet.
Attach picture show an excel file which I have imported to R Studio and it had column names which was actually dates on excel but upon importing it on R Studio the dates changed to numbers which R is considering as character as they are column names, Can anyone help changing these numbers back to dates.
Now I know to change the number its a pretty simple code: as.Date(x,origin=189....)
but I want to apply it on column names which I found so far pretty hard thing to do.
Please any help will be appreciated.
