Not sure what I'm doing wrong. Can't seem to get loess values. It
looks like
loess is returning the same values as the input.
j <-loess(x1$total~as.numeric(index(x1)
plot(x1$total,type='l', ylab='M coms/y global',xlab='')
lines(loess(total~as.numeric(index(x1)),x1))
The plot statement works fine
No errors with the "lines" statement
But I don't get a smoothed value on the graph. From what I can
tell, the
reason is that loess smoothed values are the same as x1$total. In
other
words, x1$total -j$y = 0
What am I missing ?
