Hello, can anybody tell me a easy way to change the mode of an "aggregate list" to "numeric"? I found a solution but I looks cruel.
Thank's Felix PS: In the past you have asked what I am doing. I have to evaluate measures of two gauges of our university. The aim is to get an answer which one is better. > mode(MEAN) [1] "list" > mode(MEASURE) [1] "numeric" MEAN <- aggregate(INPUT[,3], by=list(INPUT[,2],INPUT[,1]), FUN=mean) MODE <- matrix(c(MEAN[,2],MEAN[,1],MEAN[,3]), ncol=3, byrow=FALSE ) x <- MODE[,1] -1 y <- (MODE[,2] -1) / 10 MEASURE <- matrix(c(MODE[,2],MODE[,1],MODE[,3]), ncol=3, byrow=FALSE ) ______________________________________________ [email protected] 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.
