Error in xj[i] : invalid subscript type 'list'

Question

I tried to split the data(bank) into training data and test data. But I somehow got an error below.How can I solve this problem?

train = bank[1:100, ]
test =         


        

Answer 1

If you set the training data like:

data[1: 100,]

Then in lm() function you use the argument:

data = bank[train,]

Alternatively you can set train like:

seq(1: 100)

as a sequence of indices, you need to use in the

lm(): data = bank, subset = train
