I am trying to build a regression model with lm(...). My dataset has lots of features( >50). I do not want to write my code as:
lm(output ~ feature1 + feature2 + feature3 + ... + feature70)
I was wondering what is the short hand notation to write this code?
You can use
.as described in the help page forformula. The.stands for “all columns not otherwise in the formula”.lm(output ~ ., data = myData).Alternatively, construct the formula manually with
paste. This example is from theas.formula()help page:You can then insert this object into regression function:
lm(fmla, data = myData).
