It always helps to say how the suggestion did not work. Jim's
function had a typo in it - was that the problem? Or did you not
change the call to ddply to use that function. Here is something
that might "work" for you:
library(plyr)
data <- data.frame(groupColumn=rep(1:5,1:5), col1=2^(0:14))
myIqr <- function(x) {
paste(round(quantile(x,0.25),0),round(quantile(x,0.75),0),sep="-")
}
ddply(data, ~groupColumn, summarise, col1_myIqr=myIqr(col1),
col1_IQR=stats::IQR(col1))
# groupColumn col1_myIqr col1_IQR
#1 1 1-1 0
#2 2 2-4 1
#3 3 12-24 12
#4 4 112-320 208
#5 5 2048-8192 6144
The important point is that
paste(round(quantile(x,0.25),0),round(quantile(x,0.75),0),sep="-")
is not a function, it is an expression. ddplyr wants functions.
