I would like to remove a loop to speed up my code.
I want to remove a loop which references the last row.
In general I want to a remove a loop which looks something like this:
for 2 to number of rows in a matrix do{
if indextrow-1 is < currentIndexRow then do something.
}
My R code:
for (i in 2:length(tUnitsort$Hour)){
ifelse(tUnitsort[i,4]>=tUnitsort[i-1,4],(tempMC
=tUnitsort[i,7]),tempMC ) #col. 4 = BlockNumber; note tests to see if the
offers have change to the next set of blocks.
ifelse(tUnitsort[i,4]>=tUnitsort[i-1,4],(tempAC
=tUnitsort[i,7]-(tUnitsort[i,8]-tUnitsort[i,9])),tempAC )
tUnitsort$MC[i] <- tempMC
tUnitsort$AC[i] <- tempAC
tUnitsort$PercentofMC[i] <- tUnitsort$Size[i]/tempMC
tUnitsort$PercentofAC[i] <- tUnitsort$AvailableMW[i]/tempAC
}
