cbind a dynamic column name from a string in R

Question

I want to cbind a column to the data frame with the column name dynamically assigned from a string

y_attribute = \"Survived\"
cbind(test_data, y_attribute =         


        

Answer 1

You don't actually need cbind to add a new column. Any of these will work:

test_data[, y_attribute] = NA # data frame row,column syntax
test_data[y_attribute] = NA   # list syntax (would work for multiple columns at once)
test_data[[y_attribute]] = NA # list single item syntax (single column only)

New columns are added after the existing columns, just like cbind.
