Hi Berend,

Thank you for your information. However, I am still not clear on the Rpmt
function please elaborate more about

- What is the purpose of Rpmt function? Why do you subtract
pmt(xrate,x,xpv) from xpmt? / What is the meaning of xpmt ?

- And what is the purpose of doing Rpmt(xpv/xpmt/2,xrate=irate, xpmt=xpmt,
xpv=xpv) and Rpmt(xpv/xpmt*2,xrate=irate, xpmt=xpmt, xpv=xpv) ?

Thank you,
Prakasit
