Raw
makeURL.R

makeURL <-
# Given a named list of key/values, concatenate to make a URL. The
# value of the entry with key 'main' is treated as the HTML page.
function(pieces) {
m <- which(names(pieces) == 'main')
keys.values <- paste(names(pieces[-m]), pieces[-m], collapse='&', sep='=')
return(paste(pieces[[m]], keys.values, sep='?'))
}
