Examples

reg <- makeExperimentRegistry("BatchExample", seed=123, file.dir=tempfile())
addProblem(reg, "p1", static=1)
addProblem(reg, "p2", static=2)
addAlgorithm(reg, id="a1",
  fun=function(static, dynamic, alpha) c(y=static*alpha))
addAlgorithm(reg, id="a2",
  fun=function(static, dynamic, alpha, beta) c(y=static*alpha+beta))
ad1 <- makeDesign("a1", exhaustive=list(alpha=1:2))
ad2 <- makeDesign("a2", exhaustive=list(alpha=1:2, beta=5:6))
addExperiments(reg, algo.designs=list(ad1, ad2), repls=2)
submitJobs(reg)
data <- reduceResultsExperiments(reg)
library(plyr)
ddply(data, getResultVars(data, "group"), summarise, mean_y = mean(y))
