View source: R/nlfitGramm.R

Description

Plot, draw regression line and confidence interval, and show regression equation, R-square and P-value. The function includes the following models in the latest version: "line2P" (formula as: y=a*x+b), "line3P" (y=a*x^2+b*x+c), "log2P" (y=a*ln(x)+b), "exp2P" (y=a*exp(b*x)),"exp3P" (y=a*exp(b*x)+c), "power2P" (y=a*x^b), "power3P" (y=a*x^b+c), and "S" (y=a/(1+exp((x-b)/c))). Of each correlation pairs the figure who has the highest R-square among these models will be saved in a "pdf" file at working dirctory.
