Hi all,
Here is my df and I want to make an averaged model of my variables based on
Time like the following:
$ Protocol : Factor w/ 48 levels "DP FS QTSE SAG",..: 2 3 43 42
$ Time : num 182 185 189 234 186 ...
$ Systemtype : Factor w/ 2 levels "Aera XJ","AERA XQ": 1 1 1
$ ADJ : Factor w/ 2 levels "auto","manu": 1 1
$ BR : int 384 384 384 384 512 384
$ TF : int 10 10 13 7 7 5 5
I split my df into quartiles for time,
df$quant=findInterval(df$Time, quantile(df$Time), rightmost.closed=TRUE)
by the column df$quant I see quartiles 1 to 4 for time, next I want to create a
new column for example for BR and if df$quant==1 then put mean of first
quartile of BR in that,if df$quant==2 put mean of second quartile of BR in that
and so on. I do the same for every numeric variable. Does anyone know how to
that?
Thanks for any help!
Elahe
