这里list1只有两个元素 - " name"和" age",每个元素中都有两个值,现在我想在每个元素中添加新值,

list1<-list(name=c("bob","john"),age=c(15,17))
list1
$name
[1] "bob"  "john"

$age
[1] 15 17
list1[[1]][3]<-"herry"
list1[[2]][3]<-17
list1
$name
[1] "bob"   "john"  "herry"

$age
[1] 15 17 17

有更简单的方法吗？

如何将结果写入t.test文件？

> x  
[1] 12.2 10.8 12.0 11.8 11.9 12.4 11.3 12.2 12.0 12.3  
> t.test(x)

One Sample t-test  

data:  x   
t = 76.2395, df = 9, p-value = 5.814e-14  
alternative hypothesis: true mean is not equal to 0   
95 percent confidence interval:  
 11.5372 12.2428   
sample estimates:  
mean of x   
11.89   

> write(t.test(x),file="test")
