$width
[1] 80
says what the width of your console is. Columns beyond this get wrapped
gently (not each row by itself) - it can be set different values if you
choose - try:
ow <- options("width")
options(width=40)
options("width")
ttbar
options(ow)
options("width")
So this is just the print function for data.frame objects doing its unsung
job. A very useful function for looking at things when they don't seem to
be what you think is str(), which concisely says what the structure of an
object is, so str(ttbar) should tell you that it is a data frame of 10
variables and 2 observations.
