Tips and Tricks - for R and Excel

On this page you can find tips, tricks and hints for using both R and Excel. At the end of each tip there are links forwards and backwards as appropriate. There is also an index of R tips and an index of Excel tips.

For most analytical purposes the combination of Excel and R is unbeatable! Excel is great as a data management tool and for preparing data for analysis. You can also use it to get an overview of your data or to make simple (and not so simple) graphs. R is an analytical "swiss army knife" and can carry out a mind-boggling array of analytical routines as well as producing great graphics.

Add comments to objects

All R objects have attributes – one of these can be a comment. You can set or view the comment attribute of an object using the comment() command. For example:

> x <- c(2, 3, 5, 4, 3, 6)
> comment(x)

> comment(x) <- "A simple numeric variable"

> comment(x)
[1] "A simple numeric variable"

Use the comment to remind you what the object is – it is easy to forget later.
