Setting a formula for GLM as a sum of columns in R

r

Solution

If you need `outcome ~ var1 + var2 + ... + varN`, then try this:

# Name of the outcome column
f1 <- colnames(train)[100]

# Other columns seperated by "+"
f2 <- paste(colnames(train)[1:99], collapse = "+")

#glm
model <- glm(formula = as.formula(paste(f1, f2, sep = "~")),
             data = train,
             family = "binomial")

Problem

I am trying to set the formula for `GLM` as the ensemble of columns in `train` - `train$1:99`: ``` model <- glm(train$100 ~ train$1:99, data = train, family = "binomial") ``` Can't figure to find the right way to do it in R...
