Data into R

There are three options to get data into R:

Enter manually (for small data sets)

Import spreadsheet (CSV, or Excel files)

Open RDA files (R data files; for data already processed in R)

It is best to have no spaces in variable names as otherwise the whole name . In a spreadsheet, the variable names are stored in the first row. If the variable name contains a space, this space will be converted to a full stop “.”. However, it is generally preferable not to use spaces in variable names and adhere to conventions such as:

camelCase

PascalCase

snake_case
