Excel 问题中的日、月、年格式

Question

As part of my data analysis project in R this semester, I need to make a boxplot for the THY stock. I have a csv file that contains everything that I need to work with, however, I can't figure out why I can't tidy this up a little nicer in Excel before importing to R. I've tried the basic wrangling/tidying stuff that I learned this semester, but I am at a loss.

This is what I'm trying to accomplish:

I managed to build the Day, Month, and Year columns very easily using =DAY(A2) , =MONTH(A2) , and =YEAR(A2) commands.

However, with the new csv file I downloaded from Yahoo Finance, I get this:

I used the same commands, =DAY(A2) and I can't figure out what I'm doing wrong. Can someone please tell me what I'm doing wrong?

Answer 1

Without your excel file I can't be certain, but I'm pretty sure you have a formatting issue.

Change the format of column B to 'General'.
