Usage

weight.plot(fit.object, group.names)

# NOT RUN {
data("WQSdata")
group_list <- list(c("X1", "X2", "X3"), c("X4", "X7"), c("X5", "X6", "X9", "X8"))
chem_groups <- c("PCBs", "Metals", "Insecticides")
x.s <- make.x.s(WQSdata, 3, group_list)
X <- make.X(WQSdata, 3, group_list)
Y <- WQSdata$y
results <- gwqs.fit(y = Y, x = X, x.s = x.s, B=1, func = "continuous")
weight.plot(results, chem_groups)
