Visualize values of parameters

Plot the parameters that have the greatest variance in the experiments of a model.

plot_params(exp)

Arguments

exp	An object of class experiment.

Value

Returns a vector of the variables with highest variances.

Details

From the list of all parameters of the experiments that do vary (i.e. not null) the one (up to 3) with the biggest variance are ploted in 3D, 2D and 1D.

Examples

df <-   data.frame(S0 = c(900, 800, 500), # this is a data frame of 3 lines
                  I0 = c(100, 200, 500),
                  R0 = 0,
                  beta = c(1.4, 1.5, 1.6),
                  gamma = .15,
                  S = c(1, 2, 3),
                  I = c(2, 4, 6),
                  R = c(10, 20, 30),
                  nbiter = 1000,
