Getting data into R

Tidying data in R

Getting the data in

We will need to teach people to install the googlesheets library for importing data from Google Sheets.

• Import from Google Sheets
• Import from .csv and/or .xls

Testing the data is what was expected

• head(), tail()
• stem()
• summary()

Improvers

I'm going to use the above link to focus a 20 minute tutorial on 3 common mistakes:

1. Column headers are values, not variable names
2. Multiple variables are stored in one column
3. Variables are stored in both rows and columns

There are 2 other instances of untidy data, but I won't delve too much into it.

I've already written a little powerpoint presentation that I have presented to the SHOs regarding tidy data so it'll be an extension of that.

Column headers are values, not variable names

• Example with Income and Religion table

Multiple variables are stored in one column

Variables are stored in both rows and columns
