Hi,

I need to fit a piecewise linear regression.

x = c(6.25,6.25,12.50,12.50,18.75,25.00,25.00,25.00,31.25,31.25,37.50,37.50,50.00,50.00,62.50,62.50,75.00,75.00,75.00,100.00,100.00) y = c(0.328,0.395,0.321,0.239,0.282,0.230,0.273,0.347,0.211,0.210,0.259,0.186,0.301,0.270,0.252,0.247,0.277,0.229,0.225,0.168,0.202)

there are two change points. so the fitted curve should look like

\
 \ /\
  \/ \

       \
        \

How do I do this in R ?

Thank you,
Abhyuday
