I have the following object setClass("buyer", representation( reqstock="numeric", buyout="numeric"), )
nBuy <- 5 #Set buyer parameters here buylist <- list() for (i in 1:nBuy){ buylist[[i]] <- new("buyer") buylist[[i]]@reqstock <- sample(c(50:200),1) } and want to count the number of objects in buylist that have reqstock greater than 100. Something like this if it was a vector: length(which(buylist[[]]@reqstock > 100)) How could I do this please and where could I find more information about manipulating slots? When I try to search for this I just keep finding info on ls() and similar functions.
