Once the IF triggers in the following program, it just won't turn off:

#Here are the function code and test data needed to run the program: F1=function(size,data, gmean, samps){ stat=0 start=0 end=0 for (i in 1:samps){ end=end+size[i] term=mean(data[start:end]) stat= stat +abs(term-gmean) start=end+1 } list(stat=stat) }
samps = 4 size = c(4,4,3,5)
data = rnorm(16, 2*rbinom(16,1, .4))
data = data +c(2,2,2,2, 0,0,0,0, 0,0,0, 0,0,0,0,0)
gmean = mean(data)
stat0=F1(size,data,gmean,samps)
stat0 is a list, so the comparison in the "if" statement should be
if(stat0$stat <= statp$stat)
Also, you should be more clear about the statement, "it just won't turn off...". I have no idea what that means.
