[R] Changepoints estimation in a data series

Dear All,

I'm trying to find changepoints in a data series  which only consist of  11 measurements of altitude(x) and temperature(y), respectively, in which the data are as followed:

y = 16.3, 16.2, 16.1, 15.6, 14.2, 10, 8.2,  8.0, 7.5, 7.3, 7.2
x = 1,  2,  5, 10, 15, 20, 25, 30, 40, 50, 60

From the above series, i reckon there is more than one changepoint and  presuming there is a package in R which might enable the estimation on such changepoints.

Could someone please advice me on this matter by using R?

Cheers,
FMH
