Hi,

I need to find a equation which can be used to describe this data. I'm not sure on how to obtain the equation using R (i am beginner in this). First I plotted a graph and found my input data is not linear so i checked for non-linear model.I performed Power and polynomial function and got very similar R-square values. I am not sure how to interpret the results and get the best fit model (equation) to this data. Can anyone please help in this. My input data is given below:

• genomes(x) genes(y)
• 153621 26752
• 151621 26986
• 159621 26065
• 101621 35259
• 21621 78756
• 155621 26503
• 121621 31358
• 141621 28308
• 81621 40520
• 157621 26282
• 160621 25963
• 61621 47846
• 161621 25868

Thanks in advance !!
