Save a vector of model objects

[eitan lifshits]

Hi,

Is there a general way of keeping multiple similar models objects in a vector (like in C#)?

This, to be also applied for predictions as well.

Something like 

for(i in 1:100) {

data.bs = bootstrap(data)

ModelsVector[i] = Model (Response~., data.bs,...)

}

Thanks

list?

You mean list of lists?

Can i use the function pred.model?

Can you give an example?

You can use any R object to replace lm1 (the lm object).

list_of_models <- vector("list", 100) 

​for (i in 1:100){

lm1 <- lm(y ~ x, subset = sample( ...whatever... ) )

list_of_models[i] <- lm1

}​

Then, you can use sapply to create lists based on the lm object):

list_of_models %>% sapply(function(x) x$fitted )

or 

list_of_models %>% sapply(function(x) predict(x) )

[[equivalent to sapply(list_of_models, function(x) predict(x) )]]

Thanks!

Just needed to add 

list_of_models[[i]] <- lm1

list?
