Arguments

f_rast

Population density of the grid a farm plant resides. This is filled from bottom to top, then left to right.

b_rast

Population density of the grid a backyard plant resides. This is filled from bottom to top, then left to right.

farm_pos_cat

A data frame of the intial conditon:

ro

The row at which the cell containing a farm lies in

co

The column at which the cell containing a farm lies in

cat

The category that the cell/farm belongs to

vis_int

Revisit interval

tim_lst_pos

Time of last positive

nb_round

Number of round of revisit

sweep

Decide whether to carry out the sweep over the farm: 0->no and 1->yes

vis_int_per_cat

A data frame of the visiting intervale for the alternative strategy:

cat

The category that the cell/farm belongs to

vis_int

Revisit interval

param

Indicating a data frame containing a vector of parameters including:

epsion

beta_0

Baseline or average transmission rate. See func_time_beta

beta_1

Amplitude of the seasonality. See func_time_beta

alpha1,alpha2

mu_lat,var_lat

mean and variance of the latent period. See E_to_I for details.

t0

Time at which the primary source became active

.

omega

Period of the forcing. See func_time_beta

gama

The mean proportion of short range dispersal events.

.

pop_grid

Population density of the grid a case resides. This is filled from bottom to top, then left to right.

grid_size

Grid resolution //@inheritParams circle_line_intersections

age_level

Vectors of age level and the propportion of each age group respectively. See details.

age_dist

Vectors of age level and the propportion of each age group respectively. See details.

m_start

The size of initial cases. Default is 1.

t_b

Time representing the end of the baseline programme or the start of the alternative programme

t_max

Final observation time.

t_intervention

Start of the intervention if any.

t_obs

End of the observation time.

EI_model

Take integer values to specify the type of model used for the latent period. See E_to_I

kern_model

Take integer values to specify the type of dispersal kernel used. See Samp_dis

rad

Sweep radius

sweep_prop

A two element vector represention the proportion of plantation to consider for the sweep

back_p

A two element vector represention thes Backyard assessment proportion within sweep radius:

rate_det

Detection rate.

1st element

Detection rate for the grower

2nd element

Detection rate for the expert

int_det

Three elements vector representing the revisit intervals:

nb_in_b

The number of initial plants infected in category B farms

nb

The scaling factor of backyards

leav

The number of leaves to consider as a measurement for removal: 3 for expert to have a 100 detection
