I am scrapping data from a website, and in this context, data tidying gets kind of hard.
what I have right now is a string of numbers that go into a sequence, let's say
a<-c(1,2,3,1,2,3,4,5,1,2,3,4)
The first value that I'm looking for is 3, the second one is 5, and the third one will be 4. So basically, I want to go through the sequence 1:5 and choose the highest value, to have the final output as
a<-c(3,4,5)
I thought about choosing the maximum values, such as
a<-sort(a, decreasing = T)
a<-a[1:3]
But this won't count, cause the final product is:
[1] 5 4 4
where the small values are discriminated. Any ideas if this could be possible?
sort(unlist(lapply(split(a, cumsum(c(1, diff(a)) != 1)), max), use.names = FALSE))
#[1] 3 4 5
