[R] Boxplots with similar number of classes....

I have four boxplots, stacked on top of one another (vertically). There are five classes that the continuous variable is set against. The problem I have is the data for the second boxplot only contains values for four of the five classes. I would like to include the space in this graph so there i

Re: [R] Non-linear regression

Agreed, it would be simple to propose the relationship, however the regression is necessary to model the data properly. Unfortunately a simple decay based on those two points does not have the proper shape necessary. This is due to an extreme amount of zero inflation with this fisheries data. On

[R] Non-linear regression

So I have a data set I would like to model using a non-linear method. I know it should be an exponential decay. However I know what the first derivative of the equation should be at two points, x=0 and x=100. Is there anyway to establish this when inputing the model or how would one go about this
