The previously solution missed out on a cool R trick for swapping items. As R is 1-indexed, we have made some minor adjustments to the given pseudo-code. Otherwise, we have aimed to be faithful to it.
<lang rsplus>cocktailSort <- function(A)
{
repeat
{
swapped <- FALSE
for(i in
{
if(A[i] > A[i + 1])
{
A[c(i, i + 1)] <- A[c(i + 1, i)]#The cool trick mentioned above.
swapped <- TRUE
}
}
if(!swapped) break
swapped <- FALSE
for(i in (length(A)-1):1)
{
if(A[i] > A[i + 1])
{
A[c(i, i + 1)] <- A[c(i + 1, i)]
swapped <- TRUE
}
}
