Multiple unions

Question

I am trying to do unions on several lists (these are actually GRanges objects not integer lists but the priciple is the same), basically one big union.

x<         


        

Answer 1

ok this works but I am curious why sapply seems to have its own scope

x<-sort(sample(1:20, 9))
y<-sort(sample(10:30, 9))
z<-sort(sample(20:40, 9))
mylists<-c("x","y","z")
emptyList<-vector()
for(f in mylists){emptyList<-union(emptyList,get(f))}
