Hi all, I have a very large binary vector, I wish to calculate the number of 1's over sliding windows. this is my very slow function slide<-function(seq,window){ n<-length(seq)-window tot<-c() tot[1]<-sum(seq[1:window]) for (i in 2:n) { tot[i]<- tot[i-1]-seq[i-1]+seq[i] } return(tot) } this works well for for reasonably sized vectors. Does

Dear all, I have the following data frame: > raw.count Var1 Freq 1 AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA 707 2 AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAC 14 3 AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAT 3 But why when printint it using 'cat', it doesn't print the desired string "AAA" ? > cat(raw.count$Var1,

Hello All, I have had considerable bad luck with attempting the following with for loops. Here is the problem: # Suppose we have a data.frame with the following data, which can be considered a type of edgelist (for those with networks backgrounds): # # V1 V2 # 1 A # 1 A # 1 B # 2 A # 3 C # 3 A # 3 C # 3 B # # I want the output of the function to produce a matrix, such that #each factor of
