Hi,
I have a vector of start positions, and another vector of stop positions,
eg start<-c(1,20,50)
stop<-c(7,25,53)
Is there a quick way to create a sequence from these vectors?
new<-c(1,2,3,4,5,6,7,20,21,22,23,24,25,50,51,52,53)
the way Im doing it at the moment is
pos<-seq(start[1],stop[1])
for (i in 2:length(start)){
new<-seq(start[i],stop[i])
pos<-c(pos,new)
}
This works on small data, but its very inefficient on large vectors, and
is taking forever!
Anybody no a better way?
many thanks,
Chris
