Creating models for each group in dataframe column in R
I would like to create a naiveBayes model per group of values of column TN.
Here is the code:
library(party)
airq <- subset(airquality, !is.na(Ozone))
ct <- ctree(Ozone ~ ., data = airq, controls = ctree_control(maxsurrogate = 3))
airq$TN<-factor (ct@where)
Here is an example:
> tail (airq)
Ozone Solar.R Wind Temp Month Day TN
1 7 49 10.3 69 9 24 2
2 14 20 16.6 63 9 25 5
3 30 193 6.9 70 9 26 3
4 14 191 14.3 75 9 28 2
5 18 131 8.0 76 9 29 5
6 20 223 11.5 68 9 30 3
I want to build a NaiveBayes model per value:
model[i] <- naiveBayes(Ozone ~ ., data = dat[i])
dat[1] will contain lines 1 and 4 (TN=2) for creating first model,dat[2] contains lines 2 and 5 for (TN=5) for the second model, dat[3] contains lines 3 and for third model (TN=3).
So finally, I'll be able to sum it up: for each unique group values in TN I'll have its model.
Like this:
TN_val model Based on Source_Lines
1 2 model[1] 1,4
2 5 model[2] 2,5
3 3 model[3] 3,6

Hi @LAP, Thanks. How can I get the relevant value of TN per the model?

The name of the list element will be equal to the value of the TN for each model in the list. So if you'd usemymodels <- lapply(split(airq, airq$TN), function(x) naiveBayes(Ozone ~ ., data = x)),names(mymodels)[1]would display the TN value of the first model.

Thanks again @LAP. One more question: I have an additional of airq dataframe (for testing). I would like to run (predict) the mymodels on the new data per line per TN value. How can I do it?
