I must be going about my idea really backwards. I have functions like so:
Nasa_PART_Bounds <- rbind(Nasa_PART_Bounds, c("Nasa_PART_B1"))
Nasa_PART_B1 <- function(l,u) {
l[["Nasa_PART_B1", "CYCLOMATIC_COMPLEXITY"]] <- 8
u[["Nasa_PART_B1", "CYCLOMATIC_COMPLEXITY"]] <- 60
l[["Nasa_PART_B1", "LOC_TOTAL"]] <- 73
}
Where I add the function names of each "bounds" function to a list,
which later on get called with two variables.
dispatch2 <- function(f, x, y) {
eval(call(f, x, y))
}
for (i in bounds) {
bb <- eval(substitute(foo[,1], list(foo=as.name(i))))
rr <- lapply(bb, dispatch2, lb, ub)
}
However, I don't know how to do this in a better "R" way. I think my C and
pearl experience is showing through... :(
