[R] exponential day

Hi, Please, how can I determine parameters from exponential equation Example one: y = a*exp(-b*x); how do I determine �a� and �b�, as well as R-square from data sets. And also fitting y = a*exp(-b*x) into the data sets Assuming data sets A = (0,2,4,6,8,10) B = (1,0.8,0.6,0.4,0.2,0.1) Thanks Fra
