[R] Problem with unlist
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] 23.3 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?

Re: [R] Problem with unlist
My guess is that some of the Pluv3Meses elements have more than one value. Have you checked your data to see if this is the case?
