> library (faraway)
> data (pima)
> pima
> summary (pima)
好像省略 data (pima) 那一步也不影响后面其他命令啊，confused 中 | s*****n

As from R version 2.0.0 all the datasets supplied with R are available
directly by name. However, many packages still use the earlier convention in
which data was also used to load datasets into R, for example
data(infert)
and this can still be used with the standard packages (as in this example).
In most cases this will load an R object of the same name. However, in a few
cases it loads several objects, so see the on-line help for the object to
see what to ex | i******a
