Hi,
I am trying to make a sequence and am using a for loop for this. I want to
start off with an initial value ie S[0]=0 then use the loop to create other
values. This is what I have so far but I just keep getting error messages.
#To calculate the culmulative sums:
s<-rep(0,207) #as this is the length of the
vector I know I will have
s<-as.vector(s)
s[0]<-0
for (i in 1:length(lambs)) # where lambs is a vector of
length 207 consisting of temperature
values
{
s[i]<-s[i-1]-mean(lambs)
}
I continually get the error message:
Error in s[i] <- s[i - 1] - mean(lambs) : replacement has length zero
When I merely use s[i]<-i-mean(lambs) it works so there is obviously
something wrong with the s[i-1] but i cant see what. All I want is for each
S[i] to be the previous value for S - the mean!
