Conditional cumulative sum
Dear List,
I'll appreciate your help on this. I'm trying to create a variable as in
"cumsum_y.cond1" below, which should compute the cumulative sum of "y"
conditional on the value of cond==1.
set.seed(1)
d <- data.frame(y= sample(c(0,1), 10, replace= T),
cond= sample(c(0,1), 10, replace= T))
y cond cumsum_y.cond1
1 0 0 0
2 0 0

R-Help
I am trying to create a frequency distribution and I am a bit confused.
Here are the commands I have entered:
> data <- read.csv(file="40609_sortedfinal.csv",head=TRUE,sep=",")
> NumberOfActionsByStatus = data$STATUS
> NumberOfActionsByUser = data$ETS_LOGIN
> NumberOfBidOffer = data$BID_OFFER
> NumberOfActionsByUser.freq = table(NumberOfActionsByUser)
