may question addressed , answered in so, couldn't able find out. i'm computing cumulative sum conditions on large data frame. @ below example data=data.frame("catg"=c("a","a","a","a","a","b","b","b","c","c","c","d","d","d","d","d","d","d","d","e","e","f"),"val"=c(67,42,12,32,28,1,11,9,38,61,75,99,22,44,89,99,51,34,82,99,74,42)) res=null uniqcatg=unique(data$catg) for(i in 1:length(uniqcatg)) res=c(res, cumsum(data[data$catg==uniqcatg[i],"val"])) data$res=res data is there smart way without loops? (like apply functions) or plyr::ddply ... require( plyr ) ddply( data , "catg" , transform , res = cumsum(val) ) # catg val res #1 67 67 #2 42 109 #3 12 121 #4 32 153 #5 28 181 #6...
