Answer 1

您可以通过以下代码了解...

### Data generte.....
sample.no<-seq(1,14)
dates<-c("1976-04-17","1976-07-02","1976-09-19","1976-12-15","1977-02-18",
"1977-04-30","1977-06-24")

catch<-matrix(rbinom(25,20,0.5),5,5)
colnames(catch)<-c(10,20,30,40,50)


### Including within list named 'Yourdata'
Yourdata<-list(sample.no,dates,catch)
names(Yourdata)<-c("sample.no","dates","catch")
Yourdata

输出：

$sample.no
 [1]  1  2  3  4  5  6  7  8  9 10 11 12 13 14

$dates
[1] "1976-04-17" "1976-07-02" "1976-09-19" "1976-12-15" "1977-02-18"
[6] "1977-04-30" "1977-06-24"

$catch
     10 20 30 40 50
[1,] 11  8 11  8  9
[2,] 10 11 12  8  9
[3,]  9  8  8  8  9
[4,] 12 12 11 10 11
[5,] 11 10  9  9 15
