I didn't really know what to post as the topic subject, but I have a vector, for instance (2,2,4,6,2,4,4,6,8,6) and I want to create another vector which is just numbers from 1 to 4 since there are only 4 unique numbers in my vector, so for instance 2 would be 1, 4 would be 2, 6 would be 3, and 8 would be 4, so my new vector would be (1,1,2,3,1,2,2,3,4,3). The vector I have has longer

Hi, I have a vector of time in days t<-1:48. I have observations and the day they were recorded. I also have a vector, S which takes different values depending on which day the observation was recorded. For example if on day 1 all in vector S get a value of 46/48, on day 2 get 42/48, day 3 38/48, decreasing by 4/48 each time until day 12 gets the value 2/48. Then for any day greater than 12

Hi all, I have a problem with getting my code to do what I want! This is the code I have: create.means.one.size<-function(nsample,var,nboot){ mat.x<-matrix(0,nrow=nboot,ncol=nsample) for(i in 1:nboot){ mat.x[i,]<-sample(var,nsample,replace=T) } mean.mat<-rep(0,nboot) for(i in 1:nboot){ mean.mat[i]<-mean(mat.x[i,]) } sd.mean<-sd(mean.mat) return(mean.mat) } where
