hi ,everyone,
I have a script shown as below:
> bj2=bjerrdata$tyerr[bjyearnum[2]+1:bjyearnum[3]]
> length(bj2)
[1] 448
while
> b=bjyearnum[3]
> a=bjyearnum[2]+1
> bj1=bjerrdata$tyerr[a:b]
> length(bj1)
[1] 169
it is different with bj2 and bj1 . and the array bjyearnum is
[1] 0 279 448 633 1021 1365 1813 2237 2839 3314 3798 4157 12
why bj1 is 169 while bj2 is 448 ?
how to let bj2 is also array with the length 169 ?
thank you .
