Problem in Fitting model equation in "nls" function
Dear R users,
I am struggling to fit expo-linear equation to my data using "nls" function. I am always getting error message as i highlighted below in yellow color:
### Theexpo-linear equation which i am interested to fit my data:
response_variable = (c/r)*log(1+exp(r*(Day-tt))), where "Day" is time-variable
## my response variable
rl <- c(2,1.5,1.8,2,2,2.5,2.6,1.5,2.4,1.7,2.3,2.4,2.2,2.6,
2.8,2,2.5,1.8,2.4,2.4,2.3,2.6,3,2,2.6,1.8...
