20151112 - R Basics

Using R & R Studio

Before Using R Studio - Data formatting
  • Use CSV files
  • Organize data in columns
  • If data in rows -> transpose in spreadsheet to columns
  • Deal with outliers in spreadsheet before R
  • Use column headers (no spaces in header labels)
  • Leave empty data cells empty; don't use "NA"
  • Spreadsheet to CSV -> Save As... (only saves current sheet)
  • Import into R Studio - Don't forget to press "yes" radio button next to Heading

Examples - Basic Histogram
>plot(test$Species, type = "h")
  • plot = command to plot data
  • test = file name
  • $Species = column in file
  • "h" = specifies plot type - in this case histogram; if no type is specified, R will try to automatically generate the correct plot type.

Need internal R help?
Use: ?<command> (Replace <command> with the command you need help with. For example: ?plot

Shapiro-Wilk normality test - This evaluates whether or not a dataset is normally distributed. A low p-value for this indicates a non-normally distributed dataset.
  • shapiro.test = command
  • rppnew = file name to work on
