R GUIs
To find out the version of all R packages used, which is useful to refer to in publications
Installing packages
Sometimes a package is needed that is not part of the R installation. It is easy to install it, and all its dependencies.
Lines
Often a model will show a difference between the two levels of a factor. R makes it easy to illustrate the difference graphically.
Symbols lines and colours
Here is some code to quickly access what the colour, line and shape numbers produce.
Subset data
It is easy to create a subset of a data.frame with the subset command in R.
Sort data frame
Ordering a data frame by a particular column can be quicker than doing it in excel, if the data frame is large.
Save a plot
It is useful to save R graphics with code, so the file creation and naming can be automated.
