我有一些代码,我希望能够将它组合成一个大表。这可能吗?
cbind(sum(michelson[michelson$Expt==1,]$Speed),
mean(michelson[michelson$Expt==1,]$Speed),
max(michelson[michelson$Expt==1,]$Speed))
cbind(sum(michelson[michelson$Expt==2,]$Speed),
mean(michelson[michelson$Expt==2,]$Speed),
max(michelson[michelson$Expt==2,]$Speed))
cbind(sum(michelson[michelson$Expt==3,]$Speed),
mean(michelson[michelson$Expt==3,]$Speed),
max(michelson[michelson$Expt==3,]$Speed))
cbind(sum(michelson[michelson$Expt==4,]$Speed),
mean(michelson[michelson$Expt==4,]$Speed),
max(michelson[michelson$Expt==4,]$Speed))
cbind(sum(michelson[michelson$Expt==5,]$Speed),
mean(michelson[michelson$Expt==5,]$Speed),
max(michelson[michelson$Expt==5,]$Speed))
我很感谢一些专家的帮助!感谢

解释你想要实现的目标将有助于某人回答而不是只粘贴代码......从我的代码中可以理解,ddply似乎是正确的选择,正如@Henrik所指出的
