[R] grouping and counting in dataframe
hi all, i have a little problem, i have some code writen, but it is to slow... i have a dataframe with a column of time series and a grouping column, really there is no metter if in the first col what kind of data is, it can be a random number like this x<-rnorm(10) gr<-c(1,3,1,2,2,4,2,3,3,3) x<-cbind(x,gr) now i have to look for every row i , for this group, how much from the x[,1] is in a range from x[1,i] such x[1,i] (+/-) k (k is a another number) thanks in advance -- View this message in context: http://r.789695.n4.nabble.com/grouping-and-counting-in-dataframe-tp3325476p3325476.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] group by in data.frame
hi guys, many many thanks for all the solutions! :-D they are working great! i have another "little" question: i would like to save these groups in a new column with serial number like the solution from David, but wit integer values: 1,2,3... i do this allready but with my 1. solution and there is to much temp-data, that i dont realy nead ... if you have any idea, that'll be really great! thanks a lot ! -- View this message in context: http://r.789695.n4.nabble.com/group-by-in-data-frame-tp3324240p3325199.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] group by in data.frame
Yeah, you are right i want to post an short example what i want to do .. and in the meantime i solved the problem ... but here is: i have something like this dataframe: c1<-c(1,2,3,2,2,3,1,2,2,2) c2<-c(5,6,7,7,5,7,5,7,6,6) c3<-rnorm(10) x<-cbind(c1,c2,c3) > x c1 c2 c3 [1,] 1 5 0.08279036 [2,] 2 6 0.59135988 [3,] 3 7 1.45520468 [4,] 2 7 -1.70094640 [5,] 2 5 0.13065228 [6,] 3 7 -1.12080980 [7,] 1 5 0.42779354 [8,] 2 7 -1.53111972 [9,] 2 6 0.29299987 [10,] 2 6 -0.01602095 #whith aggregate i receive this: >aggregate(x[,3],list(x[,1],x[,2]),mean) Group.1 Group.2 x 1 1 5 0.2552920 2 2 5 0.1306523 3 2 6 0.2894463 4 2 7 -1.6160331 5 3 7 0.1671974 and the problem was that i was grouping by 2 columns, so i couldn't copy the result to x. the solution was i made another column with paste(x[,1],x[,2],sep="_") and then i used the solution from this link: http://tolstoy.newcastle.edu.au/R/help/06/07/30184.html so i solved my problem Ivan, many thanks for your support and quik responses! :) -- View this message in context: http://r.789695.n4.nabble.com/group-by-in-data-frame-tp3324240p3324608.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] group by in data.frame
Hi Ivan, thanks for your replay! but the problem is there that the dataframe has 2 rows and ca. 2000 groups, but i dont have the column with the groupnames, because the groups are depending on 2 onother columns ... any other idea or i didnt understand waht are you posted ... :( -- View this message in context: http://r.789695.n4.nabble.com/group-by-in-data-frame-tp3324240p3324327.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
