Dear list, Say I have some quantile operation like this
data.frame(ID=rep(1:10,each=10),CONC=runif(100)) -> test lapply(c('mean','sd','quantile'), function(x) aggregate(test['CONC'],by=test['ID'],FUN=x)) -> temp The output temp is a list of three elements. I would like to merge the three elements into one data frame. The first two elements (the mean and sd output) are easy to handle that I just need to update the column names. The problem is the third element. Although it looks like a data frame in dimension of 10 by 6 but really is just 10 by 2. How do I coerce the third element in 10 by 6? Thanks a lot.
