Hi,
I'm using R to treat a table (with a lot of missing values) with Rulefit.
The matter is when I use the command
rfmod. Actually, I don't know how to deal with the error message. I
don't
know were "true" or "false" is missing.
Someone can help me?
Thanks
The following part is the script I used with the error at the end.
platform = "windows"
rfhome = "C:/Rulefit"
source("C:/Rulefit/rulefit.r")
install.packages("akima", lib=rfhome)
library(akima, lib.loc=rfhome)
save.image("C:/Rulefit/init_rulefit.RData")
setwd("C:/Rulefit")
load("C:/Rulefit/init_rulefit.RData")
library(akima, lib.loc=rfhome)
satisf1<-read.table("rulefit satisf
preop.txt",header=TRUE,dec=".",na.strings="?")
tt<-dim(satisf1)
ref<- array(1, dim=c(tt[1],tt[2]-1))
resp<- array(1, dim=c(tt[1],1))
for ( i in 1 : tt[1]) {
resp[i,1]=satisf1[i,tt[2]]
for (j in 1 : (tt[2]-1)) {
ref[i,j]=satisf1[i,j]
}
}
erreur_pred<-array(1, dim=c(tt[1],1))
rfmod = rulefit (ref,resp,rfmode="class")
