## For the singer dataset
library(lattice)
data(singer)

## Get data ready (recode to two factors)
singer$female = factor(with(singer, grepl("S",voice.part) | grepl("A",voice.part)))
singer$high = factor(with(singer, grepl("S",voice.part) | grepl("T",voice.part)))

## We will test the hypothesis that the main effect
## of "high voice" is such that high voiced singers are shorter

### Data

t = 2
N = 20
rscale = sqrt(2)/2


### Begin utility functions

posterior = Vectorize(function(delta, t, N1, N2 = NULL, rscale = sqrt(2)/2, log = FALSE){

richarddmorey

set.seed(123) # make reproducible
M = 10000 # Number of posterior samples

N = 20
# sample the IV
x = rnorm(N, 10, 5)
# regression model for DVs
y = 100 + 3*x + rnorm(N,0,10)

## Delete missing data (3 in each)

### Utility functions

# Do a single t test simulation
# report the p value
ttest.sim = function(n, func, true.mean = 0, alpha = 0.05){
  x = func(n) - true.mean
  t.test(x)$p.value
}

# Do a sequence of M t tests, report significance

getSpookyNums = function(M){
  s = tempfile() # to ensure no caching
  my.url = paste0("http://richarddmorey.org/spooky.php?n=",M,"&",s) 
  as.numeric(readLines(my.url))
}


x = getSpookyNums(10)
