Area weighted average of wind speed gridded data

Question

I have wind speed gridded data at a particular longitude and latitude. I want to calculate an area-weighted average of wind speed in R. I'm using package "ClimProjDiagsin" for area weighted average. Also, some code related to the area weighted average was given.

data <- 1:(2 * 3 * 4 * 5)

dim(data) <- c(lon = 2, lat = 3, time = 4, model = 5)

lat <- c(1, 10, 20)

lon <- c(1, 10)

a <- WeightedMean(data = data, lon = lon, lat = lat, region = NULL, 
                 mask = NULL, londim = 1, latdim = 2)

str(a)

But here I do not understand what the time and model are representing.

Here is my data sample with longitude and latitude:

data <- c(3.632576,  3.226389, 5.810934, 4.473232, 3.239784)

lat = 5

lon = 79.59

My question is how do I use my data sample in the above code to calculate an area weighted average of wind speed gridded data.

Thanks
