Sigmoidal Plots"

The following plots are generated from applying a sigmoidal fit to the data. An iterative method is used to fit the model, if the solution doesn't converge for a protein, a linear model is applied instead.

Concentrations Used in the model: r params$concentr

Figure ? Top - Bottom plot

if(params$sigmodin != 'sigmoid'){
     plot.new()
      legend('topleft', c("Linear fit applied, no sigmoidal plots available"),bty = 'n')
