Hitters {vcd} | R Documentation |
This data set is deduced from the Baseball
fielding data set:
fielding performance basically includes the numbers of Errors, Putouts and Assists
made by each player. In order to reduce the number of observations, the
data has been compressed by calculating the mean number of errors,
putouts and assists for each team and for only 6 positions (1B, 2B, 3B, C,
OF, SS and UT). In addition, each of these three variables has been
scaled to a common range by dividing each variable by the maximum of the variable.
