Create a vector of interaction terms for linear and logistic regression

Create a vector of interaction terms for linear and logistic regression

iterms(vars, nway = 2, sep = ":")

Arguments

vars

Labels to use

nway

2-way (2) or 3-way (3) interaction labels to create

sep

Separator to use between variable names (e.g., :)

Value

Character vector of interaction term labels

Examples

paste0("var", 1:3) %>% iterms(2)
#> [1] "var1:var2" "var1:var3" "var2:var3"
paste0("var", 1:3) %>% iterms(3)
#> [1] "var1:var2"      "var1:var3"      "var2:var3"      "var1:var2:var3"
paste0("var", 1:3) %>% iterms(2, sep = ".")
#> [1] "var1.var2" "var1.var3" "var2.var3"
