Hi Kwesi,
Even without the data, it seems clear that you want something like a
rolling mean. Here is a simple function that will apply a function
like "mean" to successive bits of a vector of numbers:

collapse_values<-function(x,span,FUN="mean",na.rm=FALSE) {
 for(i in 1:length(newx))

 [1]  2  3  4  5  6  7  8  9 10 11
