[R] Problem with unlist

[Luis Felipe Parra]

Hello I want to unlist the attached element getting only the first element
in each element of the list. The last element of the list looks as this:

[[5065]]
[[5065]]$Pluv3Meses
[1] 274.4
[[5065]]$PluvMesesMedio
[1] 378.2667
[[5065]]$Pluv2UltimosMeses
[1] 23.33333

So I would like to get for each element of the list the element called
Pluv3Meses. The whole list has 5065 elements but when I try to unlist it I
am getting 5081 elements I don't know why:

> length(unlist(sapply(SumaPluvi,"[",1)))
[1] 5081

Does anybody know what can be happening?

Thank You
